How Much Do Solar Panels Cost?
Saving money is Smart. Going solar is a Smart investment. Everyone asks about cost, but if your goal is to maximize how much you make from your investment, then the most important questions are “how much money will you save each month on electric bills?” and “how quickly does your solar system pay for itself?”
To calculate that payback period, you need to account for factors like the quality of your solar system, how much sun reaches your solar panels, whether you lease or own the system, the cost per watt, available tax credits, and quite a few more. Reputable solar providers can calculate those factors to show you how quickly your system will pay for itself in electric bill savings.
But understandably, you want to know how much it will cost to put a solar system on your roof. Below we’ll break down cost and some of the other major factors that you should consider.
Estimating how much home solar panels cost in 2021
One of the first questions someone interested in home solar asks is, How much do solar panels cost? It’s important to know there is not a one-size-fits-all answer because every home is different, and there are many geographic variables and federal and local tax incentives to consider.
The easiest thing to do is to contact a professional solar installer. The installer will give you a free evaluation that entails looking at your electricity bill to find out how many kilowatt hours of electricity your household typically uses and evaluating your roof and shading, to determine how many panels you’ll need. That, combined with local solar incentives your community may offer and the federal solar tax credit, will give you a full picture of how much your home solar system will cost. The good news is that no matter where you live, the cost of solar panels is coming down.
We look at the price per watt when figuring out the cost of your system, but you may find it more useful to think about the price of leasing a solar system separately from the price to own one. That’s because with a lease it’s important to think about how much you can save for each month of the lease, but when you own the system it’s more important to understand how quickly it can pay for itself.
What is the cost of individual solar panels?
Very few people are going to buy just the solar panels themselves, just like few people would buy the components of a car and build their own vehicle. We recommend you use a SunPower-approved installer for your solar system.
Yes, it’s possible to buy a single solar panel for as little as 100, but a solar panel does not operate in isolation. You need a system of hardware and software to generate electricity from the sun, including solar panels, an inverter, mounting hardware, wires and cables., It is also beneficial to have a monitoring system that tracks the production, energy use and savings of your system. And you need to consider the cost of installation and operation.
Once you get an estimate for the cost of your solar system, you should subtract the potential savings on your utility bill over time, including any incentives offered by your local or state governments. Then you’ll have a better understanding of how going solar will impact your finances.
What are the factors that affect solar panels?
The cost of a home solar system can vary, even in the same city, due to a range of factors, including the:
- Quality of the solar system
- Household’s energy needs
- Local weather
- Available roof space and shading
- Financing options selected (cash, loan, or lease)
To help you understand the price of going solar in your area, we’ve analyzed SunPower price quotes, as well as quotes gathered by third-party sources for thousands of homeowners across the country.
We found that the cost of installing a 5 kW solar system in the U.S. ranges from 11,150 to 46,100, or in other words, from 2.23 to 9.22 per watt. And that’s before considering the benefits of any available tax credits or incentives.
The chart below shows the average cost of a 5 kW home solar system in each U.S. state.
How do I know how much sun my roof gets?
The more direct sunlight your home receives, the more power the panels can produce. But there’s a little more to it than just sunlight. To see if your house is a good candidate for solar, try out a solar panel suitability checker such as Google’s Project Sunroof. Then set up an appointment for a solar consultation with an expert who’ll visit your home to inspect its orientation (solar panels facing south capture more energy), roof angle and tree shading to see if your roof will receive enough sunlight to meet your family’s electricity needs. SunPower’s solar consultations are free, online or in-person, and you can learn more about your home electricity needs and savings options.
SunPower panels are proven to be the most efficient on the market —not to mentioned unmatched at generating power in low-light situations—but, excessive shading will reduce the amount of power that can be generated.
It’s also important to know a SunPower Equinox ® solar solution has unique, factory-integrated microinverters in each panel. Meaning, if one panel isn’t producing energy because of shade, neighboring panels receiving more sunlight can still generate solar energy for your home.
What are the most efficient solar panels?
Remember that the adage, “You get what you pay for,” applies to home solar technology. Not all solar systems are alike. The quality of the technology matters in the long run. The durability, reliability and efficiency of solar panels can vary widely by manufacturer. If you settle for a conventional home solar system that might cost less out-of-, you can expect to see average (or below average) results and less savings over time. Watch these videos about the lifespan of SunPower® solar panels and their durability and reliability.
In short, SunPower panels are the most efficient home solar panels you can buy. A higher quality panel like SunPower’s might cost a little more upfront, but you’ll see a higher—and quicker—return on your investment in the long run. Our panels come with a 25-year Complete Confidence warranty and have an expected useful life of 40 years. And since they’re more efficient than other panels on the market, you’ll need fewer of them on your roof. Our panels produce up to 55% more energy in the same space over 25-years than conventional panels, ultimately saving you more money on your electric bill.
Industry measurements such as the Fraunhofer Center for Sustainable Energy Systems’ PV Durability Initiative can give you a better idea of a solar panel’s expected lifespan—a factor that can have a tremendous impact on the system’s lifetime value.
The superior efficiency and durability of high-quality panels can provide increased savings over time and lower maintenance costs. You can get a personalized SunPower solar savings estimate using our solar calculator, which lets you factor in variables like buying solar storage and/or having an electric vehicle.
What solar incentives or solar rebates are available?
There are many different tax incentives, subsidies and financing and billing solutions at the state and local levels that can make going solar more affordable. To see if you might be eligible for renewable energy incentive programs, visit the Database of State Incentives for Renewables Efficiency (DSIRE®).
If you purchase your solar system, you may qualify for the 26% federal tax credit (ITC). The full solar ITC is available to home solar owners through 2022. It drops to a 22% credit in 2023 and is scheduled to go away completely in 2024, so don’t put off buying solar for too long.

Explore the Next Generation of Solar Roofing
In a world of steadily increasing energy costs, solar energy has never looked as attractive as today — it is undeniably less expensive than fossil fuel-generated power. While bulky solar panels have been the norm for solar-powered homes, more homeowners are turning to the growing selection of solar roofing options for a more attractive roof.
Although they’re effective at producing energy, solar panels have not always been very attractive. They can be heavy, bulky, and can lower your home’s curb appeal even while they’re lowering your energy costs. A sleeker alternative, solar roofing looks more like a traditional roof made of shingles, tiles, or metal panels. But just like solar panels, a solar roof harvests the sun’s energy to convert it into electricity you can use every day.
The main drawback of solar roofs right now is the cost. Compared to the average cost to replace a roof (14,000 for a 2,000 square-foot architectural shingles roof at 7-15 per square foot) and the cost to install solar panels (18,000 for a 6-kilowatt system installed on the roof) combined, solar roofs can be more costly.
In this article, we’ll look at the different types of solar roofing, their pros and cons, and the average cost to have them installed in 2021. Is a solar roof right for your home?
Solar Shingles
Solar shingles are one of the hottest buzzwords in the solar industry right now. These highly durable roofing shingles mimic the look of a shingle roof but are embedded with silicon solar crystals. This can ideally give you the best of both worlds; an attractive roof and decreased energy bills.
Available Options
As of right now, there are four main brands of solar shingles: Tesla, CertainTeed, Luma, and SunTegra. Of these, CertainTeed is a roofing and building material manufacturer that has jumped into the solar energy game. The others began as solar companies, then branched into roofing. All these companies offer solar shingles that match the appearance of traditional asphalt shingles, concrete tiles, or shingles that have a look all their own with a sleek, black, flat appearance. The growing selection of designs means that you can have your solar cells and an attractive look that complements your home.
Advantages and Disadvantages
The most important advantage to using solar shingles is the enhanced curb appeal for your home after they are installed. Rather than large, heavy panels installed over your current roofing, a modern solar roof will look like, well, a roof. Without the panels mounted on your roof, you also don’t have to worry about leaks or roofing deterioration; solar shingles are surprisingly durable and long-lasting.
In most instances, it is recommended that you cover the entire roof with solar shingles in order to maximize your output and get the same amount of wattage as with solar panels. In some cases, it’s also possible to mix the solar shingles with other roofing materials. Depending on the manufacturer, you may need to use their non-solar shingles to create a match with the rest of the roof. For example, if you have an area that is perpetually in the shade, and you choose Tesla shingles, you will need to use Tesla’s non-solar shingles in the shady areas to match your solar shingles.
Solar shingles do have some drawbacks compared to traditional panels. Each solar shingle tends to produce less wattage than the same area of traditional panels. To equal the output of the standard 10 to 14 panels a house may need, you will need to cover your entire roof with solar shingles. On the other hand, mixing solar and non-solar shingles can provide flexibility. For example, if you want the shingles to power your garage only, you can just install them there. There may be a subtle difference in the appearance of the shingles on the two areas.
You’ll also need to make sure that your entire roof is free of debris, dirt, and snow to help keep power flowing optimally.
Average Costs
Costs will vary depending on the brand. For most solar shingles, expect to pay between 20 and 25 a square foot for most homes, around 45,000 for a 2,000 square-foot roof.
Metal Solar Roofing
Metal solar roofing is an alternative for those who want all-over solar roofing but don’t like the look or costs of shingles. A metal solar roof is essentially a standing seam roof with solar film inside the metal sections. Your roof will be nearly identical to any other standing seam metal roof — this is a roof made of metal panels with a connecting seam that sits above the panels themselves. They’ll have all the benefits of a metal roof, such as durability, but with the added bonus of solar technology as well.
Available Options
Several companies make metal solar roofing, including INroof Solar and Roofit.solar. Because the solar technology is built into the roof, their roofs look identical to a regular standing seam metal roof.
Advantages and Disadvantages
Metal solar roofing comes with many of the same concerns as solar shingles. You must install them over your entire roof to get the same benefits. And you need to keep the entire roof free of snow, dirt, and debris. One advantage of the metal roofing, however, is that snow tends to slide right off, so you’re less likely to need to get out there and do it yourself. Metal solar roofing also looks like traditional standing seam roofing and is highly durable. It’s not likely to crack or dent in storms or with hailstones, so it can outlast traditional panels.
Average Costs
start around 12.75 a square foot for a metal solar roof, which is on the high end of a traditional metal roof, but lower than the cost of solar shingles. Your costs can vary by company and design, as well as by the total size of your roof; however, you can expect the cost of metal solar roofing to start around 25,000 for a 2,000 square-foot roof.
Interlocking Solar Roof Panels
After years of high costs, solar roof panels are now the least expensive and most efficient way to get solar energy to your home. But most people don’t like the racking system, which is both visible and can damage the roof below. Interlocking solar roof panels solve these issues. Essentially, these are solar panels that install right on your roof deck — no racking or roofing material beneath them. The edges of the panels interlock and are sealed to create one, smooth, complete surface. While these are more visible than solar shingles or metal panels, they’re less obvious than traditional solar panels. They can also potentially provide more wattage for the coverage, allowing you to go off-grid more easily.
Available Options
As of right now, two companies are making this type of solar roofing: GAF and SunTegra. GAF is one of the oldest roofing manufacturers, which means that they understand the limitations of what can be placed on a roof deck. SunTegra, on the other hand, is better versed in solar technology and maximizing the output from each panel. Both can give you a sleek-looking roof without the metal racking system of traditional solar panels.
Advantages and Disadvantages
The biggest advantage of this system is its simplicity and efficiency. A traditional solar installation would start with a new roof, if you needed one, with the solar panels installed on top. But with this system, there’s no need to install a new roof because the panels are the roofing — there is no roof below the panels. As a result, the panels are less prominent than traditional solar panels, and concerns about heavy panels damaging the roof are virtually eliminated. This option also has the potential to produce higher watts than other types of solar roofing.
Depending on your aesthetics, one drawback with this system is that it will look like you covered your roof with solar panels. The panels are smooth and installed together over the entirety, but it does not look like any other roofing material currently in use today. Also, they can be more expensive than some other solar installations, particularly if you don’t need a new roof.
Average Costs
This option of solar roofing tends to be priced by the watt, much like traditional solar systems. But while a solar panel system installed on an existing roof may cost just under 3 a watt, these systems cost nearly 5 a watt, including the materials that may not be producing solar energy. This means that for a 2,000 square-foot home, you would pay between 30,000 and 35,000 for a 6,000- to 7,000-watt system.
Consider Solar Roofing
Solar panels and solar energy are getting a lot of attention with the rise of energy costs and climate change. Solar energy use in a home can even potentially increase a home’s value due to the savings it can bring. But panels aren’t the right fit for every home or installation. If you like the idea of solar energy, but not the idea of bulky panels on your roof, take a look at the different types of solar roofing available today to see if one of these might suit your needs better.

Tesla Solar Roof vs. Solar Panels: What You Need to Know
Leigh Matthews is a sustainability expert and long time vegan. Her work on solar policy has been published in Canada’s National Observer.
While a Tesla roof might seem positively futuristic and financially out of reach for many homeowners, solar shingles can be a cost-effective way to go solar. Why? Because a solar roof is both a solar electric system and a roof!

Oh, and Tesla isn’t the only name to shout from the solar rooftops. In fact, Elon Musk’s company was pipped to the post by several others making solar shingles as far back as 2005.
So, should you install a solar roof? Here are a few things to think about.
Solar Roofs vs. Solar Panels

- No change in home appearance
- Costs 20,000 – 100,000
- No drilling into your roof
- Easier to repair
- Less energy efficient
- 20 year lifespan

- Solar panels
- Solar array mounted to roof
- Costs 15,000 – 40,000
- Requires drilling into roof
- Harder to repair
- energy efficient
- 25 year lifespan
- installers available
How a solar roof works
Tesla introduced its solar roof in 2016, shaking up the solar industry forever. But how does a solar roof work?
The Tesla roof uses tempered glass shingles to replace all the standard shingles on your home’s roof. Some of these shingles are also solar panels, meaning that nearly every inch of your roof could, in theory, generate electricity.
Because most roofs have a few spots that don’t get much sunlight, Tesla Roofs also include a few inactive panels. These look the same as the solar shingles but don’t produce energy, which helps to keep down the cost of installation and saves resources.
Tesla Roofs are the only full solar roof currently available, but they’re not the only option for going solar without solar panels. In fact, the first solar shingles were brought to market in 2009 by DOW Company, and several other companies also make solar shingles.
What’s the difference? Solar shingles are just that: shingles. They’re designed to either integrate with your existing or new roof shingles or tiles or to sit on top of them. Either way, the look isn’t quite as seamless as a full Tesla Roof.
The benefits of a solar roof
There are many benefits to going solar, and solar roofs and shingles offer all these and more.
The look
Solar roofs provide all the benefits of a rooftop solar array without dramatically changing the appearance of your home. That’s because solar shingles are designed to look as much like regular roof shingles as possible. Most solar shingles can be integrated into an existing tile or shingle roof, or can be laid over top as a sort of second skin for your roof. Even if they’re attached on top of your roof’s regular tiles, the profile of solar shingles is a lot lower than with mounted solar panels.
With a Tesla Roof, all the tiles look the same, regardless of whether they’re active solar shingles or inactive tiles. This makes a solar roof or solar shingles a great fit for homeowners who don’t like the look of more conventional solar panels. A solar roof may also enable homeowners to benefit from solar without invoking the ire of homeowner associations.

Cost-effective roofing and solar combined
A new roof can be a costly proposition, as can a solar installation. What if you could combine the two and save some cash?
If your roof is due for an upgrade, consider a solar roof. Sure, it will cost more than a regular roof, but it will typically cost less than a regular roof plus a conventional solar array with similar power output.
How much does a solar roof cost?
How much does a solar roof cost? This depends on the size of your home, the availability of skilled labor, and a few other factors. It can cost anywhere from 20,000 to 100,000 to install solar roof shingles on a single-story home. For a Luma or Tesla roof, you’d be looking at the higher end of that range, plus the Tesla Powerwall battery or other battery storage.
If you’re just thinking of integrating a few solar shingles into your current or existing roof, the cost will be much lower than for a full Tesla Roof or Luma roof. Some homeowners just opt for a Band of solar shingles around the edge of the roof, for instance.
A high-performance roofing solution
Worried that a solar roof won’t be as good as a regular roof? There’s no need for concern. These roofing shingles perform just like regular shingles, only they produce electricity while keeping your home watertight and safe from the elements.
The key here is that solar shingles combine solar cells with the roof sheathing. In more conventional solar arrays, solar modules are mounted on top of shingles (or other roofing material).
Effective use of space
Solar shingles can be a great way to go solar if you have a small roof that makes a standard solar set-up difficult or even impossible. For the same reason, solar shingles can be a good choice for a roof with awkward space constraints, such as dormers, skylights, and so forth.
After all, a shingle is far smaller than a solar panel. This means you can squeeze a few shingles onto a small area and maximize your rooftop real estate. You might even decide to skip your rooftop entirely and instead install a solar roof on your garage, shed, or an auxiliary dwelling, especially if these get more sun exposure than your home.
No external wiring or roof penetrations
Standard solar arrays have to be mounted on top of roofing material, which usually means drilling into the roof. Some metal roofs allow for solar modules to be clicked into place, but regular roof shingles and tiles require solar installers to penetrate the roofing material, which can cause damage and create weak spots.
These problems are unlikely if you use an experienced and skilled solar installer, but they’re still a risk with regular arrays.
In addition, standard solar installations involve external wiring that connects the mounted solar panels to the inverter and main service panel inside your home. With a solar roof and most solar shingles, all the wiring is internal and hidden. This reduces the risk of damage from wind, rain, birds and other wildlife, and so forth.
Easier to repair and replace
Another key benefit to solar shingles is that they’re lightweight and relatively easy to repair and replace. If one or two get damaged, you can quickly replace these with fresh solar shingles or inactive shingles as needed. It’s much harder and more costly to replace or repair an entire solar panel.
Solar shingles are also built to withstand rain, snow, and wind. And if something does go wrong, most companies offer a good warranty, so you can get your shingles replaced for free. Tesla even offers a lifetime warranty for its physical shingles, which is great if you’re planning on staying in the same home for a long time. If you think you’ll move home in the next 25 years or so, though, that lifetime warranty might not be all that useful, given it’s hard to take your solar roof with you (unlike solar panels).
Are there any downsides to solar roofs?
So far, so good, but what about the disadvantages of solar roofs?
Cost and efficiency
As discussed, solar shingles aren’t cheap, despite being more cost-effective per watt. Compared to the price of a standard rooftop solar installation (15,000 to 40,000), the Tesla solar roof has been reported as ranging from 30,000 to nearly 100,000. What’s more, Tesla has shifted its dramatically, and without warning, several times, catching customers off guard. Tesla also now insists that solar roof customers buy the Tesla Powerwall battery, which raises the cost even more.
Find a Solar Energy partner near you.
High-efficiency shingles from other companies tend to be less expensive and just as efficient as Tesla’s shingles, but they’re all less efficient than the best solar panels. In general, a solar shingle typically produces between 13 and 63 watts. They need high sun exposure and a good slope to meet their maximum output, though.
Why are solar shingles less efficient than solar panels?
The main reason is that building-integrated solar panels (BISPs, or BIPVs) don’t typically allow for air to circulate underneath, which means they overheat quickly, which impairs electricity production.
This lack of efficiency combined with higher upfront costs can mean a longer payback period for solar roofs. In fact, solar roofs don’t offer anything like the return on investment of a standard solar array, unless you’re in need of a new roof anyway.
Lifespan and flexibility
Solar roofs and shingles also have a shorter lifespan than most regular solar panels. While a standard solar panel can usually keep producing electricity for 25 years or more, solar shingles usually last just 20 or so years.
One other downside of a solar roof is that it can be hard to take with you if you move. Unlike solar panels, solar roofs are custom-made to fit your home. Solar shingles or DecoTech integrated panels may be able to go with you if you move, depending on the type of roof at your new home.
Other downsides to solar roofs
While solar roofs are increasingly popular, you might not be able to find a skilled installer in your area. In contrast, conventional solar installers are easy to find, which also means the labor cost of an installation is typically lower than for a solar roof.
The same goes for solar shingles. While there are more installers for these than for Tesla Roofs, it’s still very hard to find a credentialled installer in most places, especially if you live outside of a big city.
Finally, you’ll want to consider the environmental cost of installing a solar roof. Chances are you’re interested in these products because you want to live a greener lifestyle. Sending your current, perfectly respectable roof to a landfill just so you can install a solar roof isn’t very sustainable.
Solar roofs vs. solar panels
On balance, most homeowners will be better served by solar panels rather than a solar roof. Solar panels are easier and cheaper to install, can go with you if you move, and are efficient at producing electricity.
If, however, you really hate the appearance of standard solar panels, don’t plan on moving home for many decades, and need a new roof anyway, a solar roof might be a good fit. Solar roofs are also a good choice for homeowners who love the idea of a high-tech roof with no visible wiring or significant upkeep.
As for solar shingles, these might offer a great in-between option. They’re low profile, easy to install, relatively cheap, and easier to take with you if you move. They’re typically far less efficient than solar panels though, and you’ll have an easier time finding a solar panel installer. But, if you’re replacing your old roof anyway and don’t like the idea of solar panels, consider hanging a few shingles to cut your utility bill.

The next solar revolution: Everything will be a PV panel
Sustainability. The Rapid advancements in solar technology and decreasing costs are paving the way for a future where buildings generate their own power.
Analysis
Roofit.Solar roof construction
By Merien ten Houten
Solar panels are becoming more affordable, resulting in a construction transformation where buildings generate their own power with minimal extra costs. As the price of solar panels decreases, they are being integrated into buildings, making them more visually appealing and functional. Companies like Roofit.Solar offer integrated solar metal roofs, combining durability and aesthetics, while other innovations like see-through solar panels enable energy-producing Windows. Solar highways are being developed and energy-efficient solar shingles are already available.
From add-on panels to integrated photovoltaics
The rapidly decreasing costs of solar panels are leading to a new era in building construction, where solar technology is integrated into the very fabric of buildings rather than being added on as an afterthought. This change has far-reaching implications for the aesthetics and functionality of buildings, as well as the potential for increased renewable energy generation in urban environments.
One such example of this shift in FOCUS is the development of building-integrated photovoltaics (BIPV). BIPV replaces traditional building materials, like glass and roof shingles, with solar-integrated materials that serve dual purposes: generating electricity and providing insulation, noise reduction, and weather protection. This presents a myriad of opportunities for customization, design, and improved energy efficiency in buildings.
Disrupting the construction industry
As solar panels become more cost-effective, there is a growing trend towards integrating photovoltaics into various aspects of building construction. Solar Windows, solar facades, and solar roofs are all BIPV options that can be installed during construction or retrofitting of buildings, transforming the way we think about traditional construction materials.
For instance, solar glass using photovoltaics can be used in fixed Windows, punch Windows, and curtain walls, among other applications. This innovative approach to construction not only generates clean energy but also enhances the aesthetic appeal of buildings.
Overcoming challenges and embracing opportunities
While the adoption of BIPV faces challenges such as high costs and lack of awareness among builders and businesses, recent interest in functionality has led to decreasing and increased affordability. Education on pricing programs and showcasing practical use towards net-zero energy building initiatives can help combat misconceptions and encourage the adoption of BIPV technology.
The new solar cell is made of the same material as 95% of all current solar cells but performs much better at 26.81% efficiency.
over, technological advancements in energy efficiency and solar material transparency offer further opportunities for the broader adoption of BIPV in various applications. The construction industry must challenge traditional materials by demonstrating the efficiency and effectiveness of BIPV, paving the way for a new generation of sustainable and energy-efficient buildings.
Transforming urban environments
BIPV has the potential to revolutionize urban environments by integrating aesthetically appealing and energy-efficient photovoltaics into buildings and infrastructure. Examples of this transformative technology include semitransparent organic solar cells for power Windows and façades, as well as solar shingles that blend seamlessly with roofs.
Furthermore, solar highways and energy-producing cycle paths are also being developed, demonstrating the versatility and potential of integrated solar technology. The shift towards integrating solar panels into the very fabric of our built environment will not only help achieve climate goals but also redefine our relationship with renewable energy sources in everyday life.
