    At are solar shingles and how do they work?

    Solar shingles are basically solar cells that convert the sun’s radiation into usable electricity, but also, they work as the roofing material for your home. These roofing solar cells are commonly shaped into shingles or tiles which are seamlessly arranged to provide structural support for the house roof and other types of buildings.

    Using solar shingles allows you to have a roof that achieves two functions: generate clean energy and give your home, office or any other of your buildings, an aesthetic look.

    Composition/Structure

    Solar shingles or tiles are made of solar cells that are commonly manufactured using semiconductor materials, such as monocrystalline silicon and copper-indium-gallium selenide. The cells are assembled in bands or strips to form the shingle or tile shape.

    In addition, since solar shingles are quite thin, this allows them to have greater flexibility and be lightweight.

    How do solar shingles work?

    Solar shingles or tiles perform as roofing material for your home. The main idea is to combine the solar cells with the roof sheathing rather than mounting solar modules on top of the shingles.

    Solar shingle’s basic principle works just the same as with conventional solar panels. In other words, the PV cells absorb sunlight in order to produce a flow of free electrons, which results in generating an electrical current that can power electrical equipment. The difference between solar shingles and solar panels is mainly their construction.

    Why should you choose solar shingle technology?

    In order to help you analyze whether choosing solar shingles for your photovoltaic system is the right option, we summarize and list the pros and cons of having them:

    Pros

    • Perfect solution for those cases in which a roof replacement is required.
    • Elegant and sleek design provides a futuristic look to your roof.
    • No obstructions from solar panels will be visible on the roof.
    • No external wiring that could be exposed to damage and cause potential hazards.
    • No weak spots on the roof from roof penetrations as with conventional solar systems.

    Cons

    • Higher upfront costs and lower return of investment (ROI) than conventional rooftop solar panels (unless roof is to be replaced).
    • Solar shingles generally have less energy efficiency than standard solar modules.
    • Few companies perform solar shingle installation.

    What is the average cost of solar shingle technologies?

    The amount of money you are going to pay for installing solar shingles in your roof is going to depend on your energy usage, the conditions, and age of your roof, the solar shingle manufacturer, and other factors.

    However, the cost of going with solar shingles can go anywhere from 20,000 to 70,000 whereas Tesla’s solar roof is generally located in the high-end scenario.

    Reviews of the best solar shingle brands

    Tesla’s Solar Roof

    Elon Musk presented the Solar Roof back in 2016. Since then, the product has gained huge popularity across the U.S. and other countries.

    It’s clear that the Solar Roof provides a futuristic and sleek look for homes and other types of buildings. Although, the Solar Roof is quite an expensive product and still not as efficient as conventional solar panels.

    Tesla’s Solar Roof consists of a rooftop built with solar shingles that contain solar cells. There are two types of shingles used in the final product design: the active ones, those which produce electricity, and the inactive ones, which just act as a roofing material. Let’s take a look at the pros and cons of using the Solar Roof.

    Advantages

    • Aesthetics: Solar Roof offers 4 different styles of tile. All have a modern and distinguished looking design.
    • Durability: It is claimed to be resistant to hail, wind, and fire, as well as to mechanical forces. Solar Roof is backed by ANSI standard tests.
    • Warranty: Offers a 25-year tile and power and weatherization warranty.
    • Renowned brand: Who is not excited to have a product of a brand like Tesla? Claimed to be one of the leaders of a zero-carbon emissions future.

    Disadvantages

    • High upfront Cost: Compared to building a new roof or replacing an existing one plus adding a regular solar system mounted on the rooftop, it can be 2 to 3 times more expensive to buy the solar roof of Tesla. Depending on the complexity of your roof, you could end up paying a total of somewhere between 40,000 to 70,000 to install the solar shingles.
    • Low ROI: Depending on many factors like your energy usage habits, the size of the system, your location, and others, the solar roof may have a very low payback in a 25-year lifetime compared to conventional solar systems. In some cases, it could simply be not economically viable.

    Considering the previous facts, it would be interesting to look for possible alternatives to buy and install solar shingles. Let’s check out some of them.

    CertainTeed Solar Shingles

    Another important brand that has been leading the roofing technology in the US for a long time is CertainTeed. It offers two different product alternatives related to solar shingles.

    Design Choices

    • Apollo Shingle ll: This design has solar shingles that can be installed in a new or existing asphalt shingle roof. The result is a combination of regular asphalt shingles and active solar shingles.
    • Apollo Tile ll: This product offers a more integrated design by using tiles that are embedded to a new or an existing concrete tile roof.

    Performance

    In both Apollo Shingle II and Apollo Tile ll systems, 14 high-efficiency monocrystalline silicon solar cells are used in every tile/shingle with a power rating of 70 watts per piece. The conversion efficiency of the shingles and the tiles are 17.2% and 17.8% respectively. In addition, both have an operating temperature that can go anywhere between.40˚C and 90˚C.

    Both systems are relatively easy to install, they are placed directly into the roof sheathing using standard deck screws, just as conventional asphalt and concrete tiles are installed.

    Their weight is much less than conventional tiles at three pounds per square foot. over, they are long-lasting withstanding up to 250 pounds per square foot. Also, they are waterproof and can resist high wind velocities of 140mph.

    Aesthetics

    Apollo II provides all-black solar shingles which look like suitable solar stripes or bands placed over the roof.

    On the other hand, Apollo Tile II matches the profile of flat concrete tiles. These tiles look like black solar laminate with a custom-colored frame that can complement a wide variety of earth-toned concrete tile colors.

    Cost

    The cost might change depending on your energy requirements, the difficulty of installation, your roof inclination, and roof age. However, some estimations are shown in the following table.

    ProductCost per watt

    These figures are estimated and subject to changes depending on the specifics of the project, which can elevate the costs by 25%.

    Warranty

    CertainTeed offers a 25-year limited power warranty claimed to be all-encompassing. The coverage includes 25 years on installation workmanship, PV cells, microinverters, and mounting system. Also, comprises 12 years on optimized inverters, 10 years on wind, and 5 years on data monitoring hardware.

    Suntegra Solar Shingles

    Another important player in the solar roofing industry is Suntegra, which claims to give a 2-in-1 roof and solar solution by providing solar cells that generate electricity and a roofing material that protects your home or building. It gives installers a cutting-edge way to integrate solar directly into the sloped roof of a house, commercial building, or carport.

    Additionally, Suntegra products are regarded to be constructed with 50% fewer materials than conventional rack-mounted PV systems and thus, they might be an alternative to adjust efficiently to your budget.

    Available Options

    • Suntegra shingles: Like the Apollo ll system, Suntegra also includes a solar shingles that are placed on a new or existing roof composed by asphalt shingles.
    • Suntegra tiles: Similar to the Apollo tile design, this system integrates to the existing concrete tiles that are inserted in combination with inactive concrete tiles. They can also be used when a new roof is to be built.

    Performance

    The solar shingles of Suntegra offer 3 different models with a range of power output between 105W and 114W. All of them use 24 monocrystalline cells per piece, capable of achieving an electrical efficiency from 15.9% to 17.2%.

    On the other hand, Suntegra tiles have lower efficiency than the shingles, ranging from 13.9% to 15.1%. Also, the tiles have 16 monocrystalline cells per piece.

    Both tiles and shingles have a maximum wind rating of 130mph and a maximum static load rating of 112 pounds per square foot or 5,400Pa. In addition, the temperature operating range is the same as the Certainteed product (between.40˚C and 90˚C).

    Aesthetics

    Both Suntegra shingles and tiles offer a low-profile, all-black, and pleasing-looking. They are characterized for being a discrete installation, almost hidden and barely noticeable from the ground level, which makes them an elegant design for any home or building.

    Price

    Just as we did with the CertainTeed shingles and tiles, estimations on the cost are shown in the table below, which are subjected to variations depending on the conditions of your roof, energy requirements, and location.

    ProductCost per watt

    Warranty

    For both shingles and tiles, Suntegra offers a 10-year product warranty and a 25-year power output warranty.

    Forward Solar Shingles

    In the few recent years, Forward startup company has had significant growth in the solar shingles market. Forward offers an engineered integration of the roof and the solar cells by the means of state-of-the-art technology and a unique aesthetic that matches the classical U.S. home.

    They offer their star product called Forward Metal Solar Roof, claimed to be a cost-effective and efficient solution that harvests a great amount of clean energy while it gives a sleek and futuristic appearance using shining metal standing seam type of roof. The system comes in 8 different possible colors to cover all requirements.

    It has a non-solar portions cost of 9.75 per square foot and a 3.75 per watt cost related to the solar parts, which are quite competitive compared to the previous brands mentioned. Also, it has a weatherization warranty of 30 years.

    The product is claimed to achieve an energy density of 19 watts per square foot while having an excellent thermal performance by the means of a passive ventilation system, which optimizes the heat dissipation and the airflow between shingles and your roof deck.

    Additionally, this design is claimed to be reliable, robust, long-lasting, and can withstand powerful mechanical forces. The most interesting fact about Forward is that they are probably the only valuable brand available that offers a solar-roof integrated solution based on metal standing seam roof type, making it perfect not only for homes but also for garages, barns, and other industrial types of roofs.

    Luma Solar Shingles

    Luma Solar is another important interesting solar shingle company that has been gaining momentum for many years in the US. It’s recognized by having solar shingles products with a high rate of electrical efficiency while also having a futuristic, seamless, and luxurious looking. Luma offers results in your house that have combinations between active and inactive solar shingles.

    The price changes depending on the conditions, roof complexity, energy requirements, and others. However, estimations set the average cost of the solar shingles of Luma at 4.5 per watt and could go up to 38 per square foot.

    Additionally, it offers a 25-year limited power warranty at 80% and a 5-year limited product warranty.

    Performance

    Luma Solar Roof claims to have solar shingles with an incredible conversion efficiency of 22,1%, which is even higher than standard solar panels. It uses 16 monocrystalline 80W cells per shingle.

    It handles a temperature operation range between.40˚C to 85˚C, having a great thermal and airflow management that maintains excellent levels of energy yields.

    Additionally, every shingle weighs 19.8 lbs., and they are designed to withstand mechanical forces of 2,400 Pa for static wind loading and 5,400 for static load snow loading.

    Aesthetics

    Luma offers a distinguished good looking for your house, not only because of its futuristic appearance but also because of the Matte black finish, which gives a sleek line.

    Are these “solar shingle technologies” right for you?

    All the products mentioned above will provide an extraordinary aesthetic view for your home. Not to mention that some of them will offer the functionality of performing as the roofing material and act as the structural support by the means of Building Integrated Photovoltaics (BIPV).

    Replacing roof or just adding solar?

    If you are only looking for a solar PV system, installing solar shingles in the roof of your home can be an interesting alternative to go with if your requirements are more focused on aesthetical objectives than on cost-effective and efficient goals. From an economical point of view, it is still hard for solar shingles to compete with conventional solar panel systems.

    However, in cases where changing your roof is necessary, solar shingles may present themselves as a more economically viable choice that combines both approaches into one for a cost similar to a solar panel system plus roof installation. In some other cases, replacing your roof may not be what you need, but the structural engineer may require you to replace the roof to make the solar panel installation feasible. If you find yourself in a situation like that, you may want to reconsider going with a solar shingle installation.

    New Home?

    Another situation where solar roof shingles can definitely be a great choice is for new houses. Choosing solar shingles since the construction process can drastically reduce the cost impact, increase your ROI, and ease the installation process.

    Compare Quotes!

    In any case, if you are interested in solar shingles, it is advisable for you to get a quote for your roof-specific layout and compare it with other conventional solar panel systems plus roofing installation quotes. This will allow you to find out which approach would best suit your needs. However, keep in mind that in the end, the house will always look better with solar shingles, which is a plus to consider for the value of your property.

    Shingled solar panels: A must-consider solar shingle alternative

    Finally, shingled solar panels are an innovative technology which is carrying out a wide range of advanced features in terms of solar energy optimization.

    They should not be confused with solar shingles, which are part of BIPV, whereas solar shingled panels are more similar to standard solar panels but with cells that are cut into several strips that are subsequently connected to form modules by the means of an electrically conductive adhesive (ECA).

    Major developments on this technology have taken place in the residential sector so far. Solar shingled panels are a promising technology that is much less expensive and more efficient technology than solar shingles.

    Final Thoughts

    We have examined multiple solar shingle products and brands with the objective to show you some of the best brands available in the market today. We learned that a solar roof shingle investment is a solution that must balance aesthetics and functionality where the new shingles of your roof will actually be generating electricity.

    However, we also learned that the decision to install it must be balanced with the costs for such type of project since they can be considerable depending on the house. New houses or cases where a roof replacement is required due to structural stability reasons, are probably the best ones for solar shingle installations. In these cases, the economics can definitely be balanced with the benefits of a high-end finish.

    Solar shingles still have a long way to go and with the variety of products available for multiple roof types that go from shingles, concrete standard tiles, and even metal standing seam, there are plenty of choices that you can consider to start generating clean energy and potentially improve the look for your house. comment

    Five solar roof shingles that aren’t from Tesla

    105 with In November 2016, Tesla CEO Elon Musk gathered a collection of investors, fans, and journalists at the Universal Studios backlot in Los Angeles, California, and revealed his vision of a solar roof—that is, tiles with solar cells integrated into them so that they look just like regular roofing tiles, except they produce power.

    Further Reading

    At the time, SolarCity and Tesla officials said that solar roof installation would begin in summer 2017. Initially, Tesla employees were the only customers, until Tesla reportedly started installing solar roofs for reservation holders in January. Eventually, that seemed to stall, too. Reports indicated that, as of May 31, only 12 solar roof systems had been installed, all in Northern California. In an August shareholder call, Musk said that solar roof installations were finally ramping up, with several hundred solar roofs being installed. The company later contacted Ars to clarify that this number included homes that were scheduled for installation, not homes that were actively having a solar roof installed. Tesla has said that it’s taking time to verify the safety of these solar roofs to make sure they’ll work for decades rather than a dozen years. In the company’s Q2 shareholder letter, Tesla wrote, We are steadily ramping Solar Roof production in Buffalo and are also continuing to iterate on the product design and production process, learning from our early factory production and field installations. We have deployed Solar Roof on additional homes in Q2 and are gaining valuable feedback from each new installation. The letter added that Tesla plans to ramp up more toward the end of 2018, so if you’re on the reservation list, you might get lucky soon. But if you’re not on the reservation list, you might want to know how you can get a solar roof without waiting on Tesla. The car company didn’t invent solar tiles—they existed as rare specialty products produced by a couple of lesser-known solar companies. In the years since, some of those companies have stopped producing or talking about solar tiles, while others have stepped into the game. So, as of October 2018, here are five solar shingle makers you might bet on to replace your old asphalt roof faster than Tesla can.

    Certainteed’s Apollo II

    CertainTeed’s Apollo II solar shingles are all active, so the aesthetic is a low-profile solar panel installation, rather than the is-it-a-roof-or-a-solar-roof aesthetic that Tesla has been going for.

    Beyond installing a rectangular solar roof area, CertainTeed can also install individual tiles. The company says its solar roofing systems are certified for the maximum fire and wind ratings as roofing systems. The Systems are also certified for safety and performance, as solar systems.

    CertainTeed is an old company with a new name; it was originally (in 1904) General Roofing Manufacturing Company. Now, CertainTeed is a subsidiary of building product company Saint-Gobain, and it specializes not just in roofing but in siding, fence, decking, railing, trim, insulation, gypsum, and ceilings, according to the company website.

    One advantage that CertainTeed has on its competitors is that its Apollo II solar shingles have been available for about five years now, and it’s possible to buy said shingles through an installer. Each shingle or tile contains 14 high-efficiency monocrystalline silicon solar cells that provide a power rating of 60 watts per solar shingle, CertainTeed says.

    In an email to Ars, Chris Fisher, manager of Solar Product Development Marketing for CertainTeed, said installation costs depend on the installer. (EnergySage says that, according to solar installation data, the cost is approximately 4.90/Watt, compared to 3.14/Watt for an average rack-mounted system and 6.40 for an estimated Tesla installation).

    Fisher said that his company’s solar shingles are four- to seven-percent less efficient than traditional rack-mounted solar panels because without air circulation under the shingles, the solar cells have to be able to work at higher temperatures (this is common to most solar shingles).

    Luma Solar

    Luma Solar has also been installing solar roofs for years, and it has roofs in more than 20 US states as well as a few in Canada and the Caribbean, according to the company’s chief advisor Marty Aquino.

    Aquino said that the price of Luma’s solar roof varies by the complexity of the system. If a customer just wants a portion of their roof solarized, then it costs about 4.50 per Watt, although an edge-to-edge custom solar system can run up to 38 per square foot. Custom roofs take into account the customer’s future energy use, their roof’s sun exposure, and the customer’s overall budget.

    Luma also advertises a higher efficiency rate for its solar shingles. The company says that because its patented shingle design allows for airflow underneath the shingle, its system has a 21-percent solar-to-electricity conversion efficiency, which is high even for rack-mounted panels. Aquino added that, because of the smaller shingle profile, our Solar Shingles will generally ‘turn on’ earlier in the day (at about one-half to almost one-third the power needed as compared with conventional solar panels at an average of 18 to 24 volts per panel to ‘turn on’).

    Luma generally seeks local installers to put in an installation, but it’s capable of doing an installation itself, as well.

    Suntegra

    SunTegra didn’t return our request for comment, and the last press release it posted on its website is dated November 2017, so we worried that SunTegra may have gone out of business. However, a solar installation company called Sunrise Solar Solutions in New York has been installing SunTegra solar shingles since June 2018.

    Further Reading

    In a phone conversation with Ars, Sunrise Solar COO Rand Manasse confirmed that his company just recently started installing SunTegra solar shingles. Manasse couldn’t confirm a price per square foot, because he said it depended on the project. But the COO added that installing SunTegra’s solar shingles generally makes economic sense for people who both need a new roof and want solar panels.

    In its recent press release, Sunrise Solar stated that it had already installed 55, 105-watt SunTegra shingles on a home in Connecticut one year ago, presumably as a pilot project.

    SunTegra’s website says its solar shingles are lightweight and use 50-percent less wiring than rack-mounted solar panels.

    RGS’ Powerhouse 3.0

    Like the Apollo II shingles, these stand out on a roof if the surrounding tiles aren‘t the same color.

    Powerhouse solar shingles were developed by The Dow Chemical Company, which installed early versions of the shingles on approximately 1,000 houses starting in 2011. RGS Energy came on the scene later, becoming the exclusive manufacturer of Powerhouse shingles as well as the warranty servicer for existing homes with the shingles.

    Currently, the company isn’t offering any older shingles for purchase because it’s ramping up to start selling Powerhouse 3.0 shingles to local roofers. (Ultimately, its customers will be homebuilders and roofers; homeowners will have to buy through one of these.) Justin Chinn, RGS’ director of sales and marketing, wrote that as of the end of September, the company had secured 111 million in written reservations from local roofers. The company is still in the process of certifying its shingles for roof installation, and it expects reservations to increase after all necessary certifications have been acquired.

    Like the Apollo shingles, the Powerhouse shingles are literally the roof (they’re not pasted flush against asphalt shingles below), and RGS expects that a Powerhouse-shingle-plus-asphalt-roof system will run 4.15 per square foot, including installation.

    Powerhouse says its 60-Watt shingles will have an energy conversion efficiency factor of 17.1 percent, which is on par with many rack-mounted solar panels today.

    Sunflare

    A Sunflare press release notes that Each cell has a by-pass diode—that means only the cell that is shaded becomes inactive in a shadow.

    Sunflare has patents pending on its snap-together electrical connectors, presumably to make cell installation and replacement easier.

    Sunflare’s solar shingles are still in the concept stage. The company released images of its concept in September, looking for feedback from roofers and residential solar installers, according to Elizabeth Sanderson, Sunflare’s chief marketing officer.

    Sanderson told Ars that the company expects its solar shingles to be ready in 18 to 24 months, and no cost-per-square-foot had been determined yet. Like Tesla’s system, Sunflare’s shingles will be a mix of active and inactive tiles. Sanderson told Ars that it hopes to obtain certification in the US first, then in Europe and Australia.

    Efficiency testing has not yet been done, so Sunflare said it couldn’t share any efficiency details at this time.

    Solar shingles convert sunlight into electricity, allowing homeowners to shrink their energy bills while reducing their carbon footprint. Solar shingles cost an average of 55,000, falling within a typical range of 35,000 to 75,000.

    Solar shingles are innovative roofing materials that let homeowners generate their own electricity, which offers a variety of benefits. Solar shingles can increase property values, reduce carbon emissions, and save homeowners money on energy bills.

    According to Angi, installing solar shingles has an average installation cost range of 35,000 to 75,000 and a national average of 55,000. When a homeowner is considering investing in a solar energy system such as solar shingles, factors that can push installation costs in one direction or another include roof size, shingle materials, permits, and household wattage requirements. Tax credits may be available that can turn an expensive installation into a much more affordable investment.

    This guide will cover the different factors that impact solar shingles cost, the benefits of choosing solar shingles, the most important questions for a homeowner to ask a contractor, and the best tips on how homeowners can save money on materials and installation.

    Factors in Calculating Solar Shingles Cost

    Solar shingles cost can vary based on several factors, including the roof’s size and pitch as well as the shingles’ brand and material. Permits and labor costs can also influence the final installation price. While the national average installation price is 55,000, this can differ locally based on local regulations and pricing. Homeowners considering solar-powered shingles will want to familiarize themselves with the following factors.

    Roof Size

    Roof size is one of the most influential factors when it comes to estimating the cost of solar shingles. Solar shingles can be priced by square footage, typically ranging from 21 to 25 per square foot.

    However, it’s important for homeowners to note that a home’s square footage isn’t necessarily the square footage of the roof. A roof’s pitch or layout can add additional square footage. Homeowners also need to know that an entire roof does not have to include solar shingles.

    Generally, a larger home will have a larger roof and higher energy needs, resulting in higher solar shingle costs. But a smaller roof can cost just as much or even more, especially if it has complex shapes or multiple peaks.

    Homeowners can use the length and width of their roof to calculate their square footage. However, a solar contractor can estimate more accurately by considering all size-related factors.

    Roof Pitch

    When estimating the potential cost of installing a solar roof using shingles, homeowners will want to keep roof pitch in mind. Roof pitch refers to the angle or slope of a roof and can vary from house to house based on the home’s style and the local climate. For example, homes built in areas with a lot of snow often have steeper roofs.

    Homeowners can expect solar shingles to cost more to install on a home with a steeper roof pitch than one with a flatter roof pitch. A steeper pitch can make installation more difficult and time-consuming, and contractors tend to charge accordingly.

    If a roof pitch exceeds the typical 6:12 ratio, homeowners can expect to pay between 5 percent and 25 percent more on installation costs.

    Shingle Brand

    Unlike solar panels, shingles aren’t very common as they are still a relatively new option. There are several brands of solar roof shingles, all with their own unique pros and cons. Differences in manufacturing, materials, and reputation also result in unique price points for each brand.

    For example, more established brands with better customer reviews may charge higher for their shingles than up-and-coming brands. Additionally, some manufacturers offer additional features or warranties that can lead to higher prices. Some of the best solar companies include:

    • Tesla: Tesla shingles are made from quartz and are known for their sleek appearance.
    • CertainTeed: CertainTeed shingles are made from high-efficiency monocrystalline silicon and are easy to install.
    • SunTegra: SunTegra shingles integrate seamlessly with traditional roofing materials and come in various colors and styles.

    Shingle Material

    Solar panel shingles are available in two primary materials. The first is copper indium gallium selenide. This semiconductor contributes to the flexibility and thinness of a solar shingle and has a relatively high conversion efficiency rate, typically ranging from 10 percent to 12 percent. Shingles with higher efficiency rates produce more electricity and can help a homeowner save more on energy bills over time.

    Some solar shingles are made using monocrystalline silicon, which is the same material used in computer chips. Shingles made from this material tend to be pricier than those made from copper indium gallium selenide, but they also have a higher efficiency rate, averaging between 15 percent and 20 percent.

    Homeowners will always want to consider a shingle’s material, as it directly influences the efficiency rate and the potential cost savings of a system over its lifetime.

    Shingle Wattage

    When homeowners are estimating solar panel roof costs, it’s essential to consider shingle wattages. Shingle wattage measures how much energy a solar shingle can produce. And just like light bulbs, solar shingles come in different wattages, costing between 3.50 and 8.00 per watt.

    There’s a relatively simple way to compare shingle wattages: If there are two shingles, one with a wattage of 25 and another with a wattage of 50, the shingle with a wattage of 50 can produce more energy than the shingle with a wattage of 25.

    Shingle wattages influence solar shingle costs because higher wattages are generally more expensive than lower wattages. However, homeowners will want to keep in mind that the cost of higher-wattage shingles can be offset by the additional energy they produce, resulting in lower energy bills.

    Household Energy Requirements

    The cost of solar panel roof shingles will heavily depend on a household’s energy requirements. Solar power systems come in different sizes and should be matched to a home based on the amount of energy its occupants need.

    Larger families with more occupants typically have higher energy needs and require a more expensive solar shingle system. The size and layout of a house can also affect energy needs, since larger homes can have more appliances or electronics that require energy.

    Energy efficiency is also essential, as homes that are more efficient require less energy to operate and can get by with a smaller and less expensive solar shingle system.

    Homeowners should refer to their current energy bills and usage to help determine what size solar shingle system is needed to meet their household energy requirements.

    Labor

    Installing solar-powered shingles requires skilled labor. Homeowners who hire out for installation can expect labor costs to influence solar shingles cost per square foot.

    The average cost of labor for installing solar roofing shingles typically ranges from 3 to 4 per square foot, though homeowners can expect to pay up to 60 percent more for complex installations, including those on steep roofs or roofs with multiple levels. Trees, chimneys, and skylights can also increase the complexity and potentially the cost of a solar shingle installation.

    Homeowners can cut labor costs by scheduling their installation during the off-season or negotiating pricing. DIY installation is also an option but should be considered only if a homeowner has the right experience, knowledge, and tools.

    Permits

    Permits are legal requirements that help ensure solar shingles are installed safely and meet code regulations. Not all municipalities require permits for solar panel roofing installations, but most do.

    Permit fees vary by location but typically cost between 100 and 1,000 for solar system installations. In addition to paying permit fees, some homeowners may need to pay for plan reviews or inspections.

    Obtaining a permit can be time-consuming but necessary. Homeowners who complete a solar shingle installation without a permit can face serious consequences, including fines and forced removal of their solar system. Working with a licensed solar contractor can help streamline the permitting process and ensure the installation meets local regulations.

    Geographic Location

    Geographic location can influence the cost of solar shingles installation in a few ways. First, the cost of living in a specific location can affect labor costs and permit fees. Climate can also influence costs, as areas with more sunlight may have a greater demand for solar installations. High demand can allow contractors to charge more, but local competition can help keep rates competitive.

    Finally, different states and municipalities offer different rebates and incentives for solar panel installations, which can help absorb installation costs and make an investment in solar more affordable.

    What follows is a chart that breaks down average installation by state to help homeowners estimate solar shingle installation costs by location.

    Additional Costs and Considerations

    There are several additional costs a homeowner will want to keep in mind when estimating how much it will cost to convert their roof to solar shingles. While not all of the following scenarios may be relevant for every installation, it’s important for a homeowner to be aware of them to avoid unexpected and costly surprises.

    Solar Shingles vs. Solar Panels

    Many homeowners wonder which is the better option when it comes to choosing between the best solar shingles, the best solar panels, and the best solar companies (such as SunPower and ADT Solar). One of the most noticeable advantages of solar shingles is their ability to blend seamlessly into a roof. Where installing solar panels can add bulk to a roof, installing solar shingles can give a home a clean and modern aesthetic, similar to painting roof shingles to update the look.

    Solar shingles cost is less than the price of solar panels, particularly when homeowners are replacing a roof. Solar shingles can also be removed and reinstalled if a homeowner decides to relocate, making this type of shingle a good investment for those not ready to plant permanent roots.

    However, solar shingles can be less energy efficient than solar panels. This can be especially true if a roof doesn’t have the best pitch or receives minimal sunlight throughout the day.

    Ultimately, solar panels that look like shingles can be a good alternative to solar panels, depending on a homeowner’s unique energy needs and budget.

    Existing Roof Removal

    In certain circumstances, an existing roof must be removed before solar shingles are installed. The process involves removing the existing roofing material, including the underlayment, and preparing the area for new roofing or solar shingles.

    It’s worth noting that an existing roof doesn’t always have to be removed before solar shingles can be installed. It depends on the type of solar shingles being installed. Some solar shingles are meant to be put directly into the roof deck, while others require removal of the old roofing material.

    Homeowners will want to budget roughly 1,250 for removal and cleanup if the existing roof is removed. This cost may be higher if there are multiple layers of underlayment and old shingles to discard.

    Warranty

    A solar shingle warranty is a guarantee from a manufacturer that the product will function as intended for a certain period of time. Warranties can also come from contractors in reference to their installations.

    Warranties are not always automatic. Homeowners may need to register their solar shingles with the manufacturer to jumpstart their warranty. The length of a warranty can vary, along with its level of coverage. Most warranties last between 10 and 25 years and cover manufacturing defects. Damage caused by severe weather or fallen debris is often covered as well.

    Choosing a solar roof tile with a longer warranty can cost more up front but can potentially save homeowners money on repairs down the line. It’s also important to note that certain actions or circumstances can void a warranty, including improper installation or lack of routine maintenance.

    Tax Credits and Incentives

    Tax credits and incentives can significantly reduce the up-front costs of solar shingle installations, making them more affordable to budget-conscious homeowners. The following are some ways a homeowner can find hidden savings when considering solar installations.

    • On the federal level: The federal government offers solar investment tax credits in a certain percentage (it changes every year) for the total cost of a solar shingle installation, including labor and materials.
    • On the state level: Some states, including California, Texas, New York, and Minnesota, offer tax credits and incentives for solar installations.
    • From the manufacturer: Some manufacturers offer product rebates to help homeowners absorb initial installation costs.

    Tax credits and incentives can change over time, so homeowners will want to stay informed of changes to avoid missing out on the best return. Also, tax credits apply only to homeowners who own their solar systems. While leasing solar panels or shingles is a great way to save on installation costs, tax credits are no longer an option in these scenarios.

    Battery Backup System Installation

    A battery backup system stores surplus energy generated by solar panels or shingles, which may then be used to power a home when there is no sunshine. A battery backup system can provide peace of mind during extreme weather events or help a property become more energy independent on a regular basis.

    Battery backup systems can be incredibly useful—but they can also be pricey, costing between 10,000 and 21,000. This includes installation, which is best performed by a licensed professional to ensure system safety and functionality.

    Homeowners installing a battery backup system may be eligible for tax credits or other incentives, which can help cover some up-front costs.

    Lower Carbon Footprint

    One of the main benefits of switching to solar shingles is that they can help reduce a homeowner’s carbon footprint. Traditional sources of energy emit carbon emissions and contribute to climate change. Installing solar shingles allows homeowners to lessen their dependence on such nonrenewable energy sources in a couple of different ways.

    To start, compared to the production of traditional roofing materials, solar shingle production is much more eco-friendly. While the manufacturing process for solar shingles does require some energy, the amount is significantly lower than for other roofing materials.

    Also, solar shingles generate their own electricity, allowing homeowners to rely less on the power grid. Lowering the electricity demand generated by power plants means fewer carbon emissions are put into the atmosphere.

    Finally, using solar shingles allows homeowners to benefit from other eco-friendly avenues, including charging electric cars with solar energy.

    Cost Effectiveness

    Solar shingles can be a cost-effective investment in a few different ways. The most obvious way solar shingles can help a homeowner save money is by reducing energy bills by generating their own electricity. Additionally, many states offer tax breaks and incentives to homeowners who install solar shingles, which can help offset some of the initial costs.

    Solar shingles can also increase a home’s value, as potential buyers may be willing to pay more for a unique and eco-friendly feature in a property.

    Finally, solar shingles are made to be long-lasting and sturdy. Because the material requires less maintenance and fewer repairs than other roofing material, homeowners can save money over the lifespan of their solar shingle system.

    Low Maintenance Requirements

    Compared to other types of shingles, solar shingles are low-maintenance and can save homeowners time and money as a result. Solar shingles have no moving parts, making them less likely to break or require repairs.

    Solar shingles also have a long lifespan and require less frequent replacement than traditional roofing materials. Homeowners who stay in their homes for decades may need to replace their roofs several times, but the frequency is likely to be less with solar shingles.

    Additionally, solar shingles don’t require regular cleanings, even if trees or other objects above the roof drop debris.

    Improved Aesthetics

    Solar shingles are an aesthetically pleasing addition to a home, as they blend in with traditional roofing materials. This is an important feature, since most homes don’t need an entire roof of solar shingles but a much smaller section instead. By seamlessly blending with other materials, solar shingles can enhance a home’s aesthetics.

    Solar shingles also come in various colors and styles, allowing homeowners to customize the look of their homes.

    Finally, compared to solar panels, solar shingles are designed to be more low profile. They’re less obtrusive than solar panels yet provide adequate renewable energy.

    Solar Shingles Installation: DIY vs. Hiring a Professional

    When installing solar shingles, homeowners have two options: Do it themselves or pay a professional.

    While a DIY route certainly offers some potential cost savings, there are vital considerations for homeowners to take into account before attempting a DIY solar shingle installation project.

    First and most importantly, checking local solar panel installation regulations is paramount. Many states and counties require permits and inspections when solar equipment is being installed. Failing to comply with these regulations can leave a homeowner in hot water. Hiring a professional installer eliminates this risk, as they are well versed in ensuring installations are up to code.

    Additionally, installing solar shingles requires a certain level of knowledge and expertise. While there are resources available for homeowners who want to DIY their installation, it’s important to know that a mistake can be costly and potentially dangerous. DIY installations may also not be covered under warranty or insurance.

    Before deciding whether to go the DIY route or hire a professional, homeowners are also advised to consider the cost differences. Hiring a professional will likely be more expensive up front but can save money in the long run. Professionals can also access discounted materials and ensure an installation is done correctly the first time.

    In fact, DIY installations don’t offer a lot of opportunities for cost savings. When installing solar shingles on their own, homeowners spend an average of 35 per square foot, bringing the total cost for a 1,500-square-foot roof to around 53,200 when all supplies are considered. This cost is similar to the average price of hiring a local professional to install a solar shingle roof.

    Ultimately, deciding to install solar shingles themselves or hire a professional depends on a homeowner’s skills, experience, and comfort level. Before deciding whether a DIY installation is the best option, it’s important for a homeowner to consider all of the factors involved. Hiring a professional is likely the safest and most cost-effective route for most homeowners.

    And, with a few of the right tools, tips, and skills, solar panel installation can be done without too much difficulty.

    This complete guide explains everything you need to know about how to install solar panels on roof like a pro.

    How To Install Solar Panels on Roof: DIY Solar Panel Installation Guide

    If you are working in construction or want to know how to install solar panels on roof yourself, know that it is not as complex as it seems.

    Still, you will need the right tools and equipment and carefully follow the instructions since you are dealing with electrical wires.

    The following are the nine steps in DIY solar panel installation (on shingles roof).

    Step 1: Assemble Everything You Need

    Preparing all the materials and tools you need is the first step to a successful project and helps save you a lot of time.

    Since you will be up on the roof, you want to avoid climbing up and down to find missing items.

    You will need the following:

    • Solar panel
    • Stanchions
    • PV wire
    • Mounting brackets
    • Drill and drill bit
    • Rails
    • Tape measure
    • Chalk line
    • Screws
    • Ladder
    • Lags
    • Anything else in your solar package and a tool belt 1

    Step 2: Mark Locations

    With your tools ready, the next step is to mark where the stanchions will be on the roof. These are vital to the installation because the sturdy metal structures carry the panels and must distribute their weight evenly across the rafters.

    You should refer to your house’s blueprint to help connect them to the rafter on the roof. 2

    While at it, ensure that the stanchions are in line (using the chalk line) before drilling and place them four feet from each other.

    Step 3: Fix Stanchions

    You should properly fix your stanchions since they will hold the panels in place.

    First, pre drill holes in the rafters and secure them with steel bolts, checking that the distance between each stanchion is at least four feet.

    Step 4: Install Flashing

    Afterward, you should fix the flashing beneath the shingles and fasten it using a bolt on the rafters. This process keeps your roof safe from leaking after poking holes and keeps the roof waterproof.

    Besides flashing, the bolts also have sealants to protect the roof from leakages.

    Step 5: Affix the Rails

    The rails are essential to installation because they securely hold the panels and attach to the stanchions. 3

    First, screw and fasten the holes, and using bolts, connect the top and lower rails, preferably using your impact driver.

    Remember to make them tight to secure them in place.

    Step 6: Check That the Rails Are Parallel (Check for Square)

    Any professional will tell you how crucial it is for the rails to be in line and parallel.

    You can take the distance between them using your tape measure, checking that the diagonal distance is the same.

    Using diagonals is the fastest way to check that they are square, and if not, you must adjust or, unfortunately, drill again.

    Step 7: Fix the Inverters

    All the steps above were merely preparations for installation; the steps from here involve how to wire solar panels, which need care and proper handling.

    First, know which wires you need and how to attach the inverters beneath each panel.

    Each micro-inverter should have six-gauge copper wires, and the connection goes into and out of the arrays.

    Route the wires from the panels to a meter, then to a sub-panel. Next, run them to the inverters through the rails, and remember to turn off the powers before wiring.

    It can be helpful to have a diagram of the wiring plan, as well as the placement of your panels before beginning.

    Step 8: Panel Placement

    When you are confident that the wiring is okay and the connections are working, the next step is to attach the panels to the stanchions you have already drilled.

    First, hook the brackets to the panels, which you can do before climbing the roof; lift them and check that they align with the rails you set up.

    Fasten each of the panels to the rails using bolts and clamps. Lastly, place the wires through the panels and the inverters to complete the circuit.

    Step 9: Connect the Inverter

    The final step is to power up your panels by linking them to the solar inverter and electric meters. 4 Shut off the power in your house before doing this and connect the inverter to the electric panel.

    If your inverter is outside, keep it under shade and connect the battery and fuse board/ consumer unit. This setup is vital because the inverters transform DC from the sun to AC you use at home.

    You can forgo the battery, but it is essential for boosting your power on cloudy days.

    You can also call in an electrician to do the actual connection, to ensure that no fire hazards have been created.

    In fact, many counties and cities require a professional electrician to perform this step, so check with your local building laws.

    What Are the Benefits of Installing Solar Panels on Roof?

    Solar panel installation is booming, and stakeholders are encouraging more homeowners to adopt it as a better option than fossil fuels for electricity generation.

    The panels use light from the sun, which is free and clean, making it an environmentally-friendly power source.

    Other than reducing household carbon footprint, solar panel has more benefits. The following are reasons why installing solar panels on your roof is worth it.

    • Low or no energy bills: Solar power is the most efficient and economical energy source. Its power comes from the sun for free, and you can use batteries to store the surplus or make net metered connections to offset electricity bills.
    • Environmentally friendly: Installing solar panels on your roof reduces your house’s GHG emissions, unlike using fossil fuels.
    • Home value increase: Besides saving on energy costs, solar panels help increase your house’s value if you have plans to resell. Homeowners are usually attracted to energy-efficient homes, and panels will be a significant selling point.
    • Easy installation: While you can hire experts to set up the system, you will appreciate how easy it is to DIY the installation. You only need the solar panel kit, tools, and a step-by-step guide.

    What To Consider During Solar Panel Installation

    Before learning how to install solar panels on roof, you should first weigh out if it is even worth it for your home.

    Several factors will guide you to determine whether solar panel installation is the way to go.

    House Location

    Where do you live? Do tall buildings overshadow your house? Are there towering trees that will block the sun? These questions will help you gauge whether solar panels are worth investing in.

    It would be a bad idea if tall buildings and trees all around cast shadows on the panels because the setup would need more sunlight, leading to low power output.

    The side of the roof you choose for the installation should point directly to sunlight for the better part of the day (Mostly the southern slope)

    Panel Elevation

    Panels harness the sun’s energy; therefore, how you angle them makes a huge difference. You should install them, making them more exposed to the sun and effortlessly receive the rays.

    While most angles are at 30-45 degrees, the best tilt depends on your location and latitude, and you can use a solar panel calculator to find the best angle based on where you live.

    The general rule is that the panels should face south if you are in the northern hemisphere and true north if you are in the south.

    Roof Condition

    Before installation, it is crucial to check that your roof is perfect. The process requires a lot of drilling and hooking of equipment and will not work if you have an old roof.

    Solar panels usually serve you for 25-30 years, meaning that your roof should be sturdy enough. It is best to fix damages, and if you have plans to change the roof, you want to do that before installing the panels.

    Otherwise, you will have to take down the entire setup, change the roof, then reinstall it, which costs a lot of time and money.

    Roof Strength

    Another crucial question is, will your roof handle the extra weight for all those years? Panels weigh about 2.5-2.7 pounds for a square foot and, in most cases, are not a danger to your roof or people living inside the house.

    However, it is safer to call an engineer or an installation expert to confirm whether your roof is in perfect shape and if everything meets the requirements. 5,6

    Tips for Solar Panel Installation: Residential

    Below are some tips for homeowners before installing solar panels.

    • Considering your roof warranty against your solar panels’ lifespan is essential. You don’t want to make costly roof repairs by removing the panels and reinstalling them.
    • In some cases, the panels are too massive for the roof, making it crucial to check your roof’s size and shape before purchasing a kit. You should also know how many solar panels do I need and check whether your roof will accommodate them.
    • Your roof’s slope also matters because the goal is to find the best location that captures more sunlight, leading to higher output.
    • When installing solar panels, you should also consider how the water drains from the roof. The panels can interfere with the water’s direction, leading to leaks, which helps address these concerns before setting up the panels.
    • If you plan to set net metering, it is best to confirm whether your state and local providers allow it. Otherwise, it will be impossible to subsidize your electricity usage when there is low solar power output.
    • The most important decision regarding solar power is who will perform the installation. If you’re unsure, it’s always best to call professionals.

    Do I Need Permission Before Installing Solar Panels on Roof?

    Solar panel installation can be a massive project that requires authorization and a permit based on your state. It is crucial to confirm that your local laws allow it and whether there are restrictions or rules before installation.

    You will only need special authorization for an electrical or building permit. However, there may be other requirements to consider, like obtaining permission from the homeowners association, utility providers, and municipality.

    If you have plans, start early because sometimes scheduling inspections and waiting for permit approvals are the most daunting aspects of the entire process. 7 Your region may also be strict, allowing only expert installers to handle the job.

    How To Install Solar Panel on Roof Based on the Roof Type

    The roof type also affects how you install solar panels on the roofs. They come in different materials and shapes that influence the process, and yours should be easy to use and energy-efficient. 8

    Metal Roof

    This roof type is one of the best and easiest to deal with because its structure allows you to mount solar panels directly.

    There is no need to make several calculations and alignments before installation.

    You only have to secure the panels using a U-clamp, making drilling holes into the roof unnecessary.

    Tile Roof

    This roof is complex, and a few ways to hook the panels exist.

    First, you can attach a unique rack to serve as a frame or remove some tiles and, in their place, insert metal shingles that are easier to drill.

    solar, roof, shingles, aren

    The trickiest are the Spanish roofs that must damage at some point during the installation, and you will have to replace the tiles afterward.

    Flat Roof

    Flat roofs are the most fun because you can make your preferred customization and adjustments. You can turn the panels to the best side and use mounts to angle them towards the sun.

    It is different with sloping roofs because you must pick a side, and it is tasking to make adjustments. 9

    You don’t have to drill the panels to secure them because you can use cinder blocks or ballasted racking.

    How To Get Solar Panels for Free

    After learning how much do solar panels cost, you will realize that installation is quite an investment.

    solar, roof, shingles, aren

    You need to buy the kits and pay for installation, which can be pricey. It pays off in the long run, however, when done correctly.

    You often hear about free solar power or no-cost solar from door-to-door salespeople; as enticing as it seems, there are no zero-cost solar programs in the country.

    These initiatives are deceitful ways to get more people to join solar leases, which are not free.

    A solar provider agrees to install panels in your home at no charge, but you must pay a monthly fee. It is similar to renting the panels or having the solar company as your electricity provider.

    In the long run, buying and installing solar panels at your own cost is cheaper. The promises are enticing initially, and many are attracted to the free installation and maintenance.

    Reading the fine print reveals that these claims are misleading and you would rather get loan financing for the project.

    Which Roof Type Is Best for Solar Panels?

    South-facing roof types are ideal in the northern hemisphere because they enhance the absorption of sun rays.

    On the other hand, metal roofs are the go-to for many because they allow easy panel installation.

    You don’t need to drill holes, and it helps that they are durable.

    What Do I Do if I Don’t Know How To Install Solar Panels on Roof?

    Most residential buildings have a roof that is well-elevated for the installation of panels on the southern slope. However, some homes have very steep pitches, making the installation process a little daunting.

    If you don’t know how to install solar panels on roof that is steep, it’s a good idea to call a professional installation company that specialized in solar panel installation.

    However, you can also mount yours on the ground on a frame in a well-lit spot near your house.

    On the downside, setups on the ground need regular maintenance, and the rules to follow may be stricter.

    How Many Solar Panels Do I Need?

    To find out how many solar panels you need for your home, you can speak with a professional, or estimate them using a calculator.

    Also, make sure that you know how many hours of sunlight your region gets, so you’ll know how many and the size required for your energy needs.

    How Much Power Does a Solar Panel Produce?

    To those wondering, how much power does a solar panel produce? The current solar panels produce 250-400 watts an hour based on several factors.

    A typical household setup has a 1kW or 4Kw. You can use the rated watts of your panel to calculate how much power it produces. 10

    Power (Watts) x Average sunlight hours = Daily Watt-hours
