First launched in 2016, Elon Musk’s Solar Roof system has taken the photovoltaic (PV) world by storm. Tesla’s Solar Roof is not the only solar roof tiles on the market but is some of the most attractive and most expensive.
Solar tiles offer a completely different approach to solar PV installations, the final product is, inarguably, far superior in aesthetic terms to traditional solar PV installations, and seeks to add a cool factor to generating your own power.
While Tesla claims its Solar Roof is competitive in terms of providing a two-for-one solution (you do get a new roof after all), ultimately, the proof of the pudding is in the eating.
So, is Tesla’s Solar Roof all it’s cracked up to be? Let’s take an honest look.
What is Tesla’s Solar Roof?
Tesla’s Solar Roof, like other solar roof tiles, is an innovative system of specially engineered roofing tiles or shingles. Unlike conventional solar PV panels that are mounted onto an existing roof, a solar roof acts as a direct replacement for existing roof coverings.
The system allows potential customers to benefit from generating their own power without unduly affecting the aesthetics of their homes. Win-win.
Tesla’s Solar Roof consists of two main types of textured glass tile shingles. The first is purely decorative and is termed inactive. These look exactly the same as the second kind, called Active, to ensure a uniform look of the finished roof.
The Active shingles are effectively small, shingle-sized solar panels that are integrated into the main roof surface in strategic places to maximize their efficiency. In most cases, most of the south or west-facing areas of a roof will consist of Active shingles, with the rest of the surface consisting of the visually similar Inactive shingles.
Active shingles, like conventional solar panels, will also be fitted as close to the best angle of incidence to the Sun’s rays throughout the year. In the northern hemisphere, this is as close to a 60 degrees inclination as possible, which, on most domestic homes is around 30-45 degrees, depending on the pitch of your existing roof.
Of course, if you choose to install a Solar Roof, your old roof will need to be stripped and replaced in totality.
The system can also be used with a Tesla Solar Inverter to convert the direct current generated by the shingles to useable alternating current in your home. While non-Tesla inverters can also be used, the use of Tesla’s own proprietary equipment ensures the systems will run with fewer potential snags.
This inverter also enables you to tag on a Tesla Powerwall battery to store excess energy, if desired.
The system was developed in a collaboration between Tesla and its subsidiary SolarCity and was first announced in 2016. It wasn’t until 2018 that Tesla and SolarCity were in a position to begin the manufacture and delivery of their first Solar Roofs, however.
Since then, Tesla has continued to make improvements to the technology, with its latest variant, Solar Roof V3, boasting the best efficiency and durability to date. The product comes with a generous 25-year weatherization warranty.
Great, but what are some of the downsides? One is whether Tesla actually serves your geographical area.
For the most part, Tesla should be able to provide an installation in most of the continental United States. However, in some states, they may use authorized installers to do so.
The same is true for other parts of the world, with the rollout continuing around the world. If you are interested in finding out if they serve your area, the best thing to do is contact Tesla, or try to get a quote, and they will tell you.
How much does a Tesla solar roof cost?
According to data from actual Tesla quotes, their Solar Wall system costs approximately 1.80 per generated watt of electricity for their Active shingles. The cost of their Inactive shingles then varies depending on the complexity of the roof in question.
For simple roofs, i.e., basic pitched roofs start at around 13.30 per square foot. For more tricky roofs like hipped roofs or multiple-level roofs, these shingles should cost about 15.30 per square foot. For more complex roofs (i.e. cross-gabled, steep or variable pitched, multiple heights, or lots of obstacles), costs could be as high as 18.54 per square foot.
You will also be charged for the removal and disposal of your old roof at a rate of around 3.55 per square foot.
Just like any solar energy installation, the actual cost will vary depending on the size of roof coverage, location, and construction of the building. Smaller pitched roofs on a single-story home will be considerably cheaper than a large complex roof on a multi-story building, for example.
This is for a variety of reasons, but chief among them are additional costs for access equipment to higher roofs or increased time in labor to design and install the roof on larger and more complex roofs like cross-gabled roofs.
Tesla may also require customers to upgrade their electrical systems in order to actually work with their Solar Roof system. Upgrading elements like electrical panels can cost anywhere in the region of 5,000 and up.
However, to give you a rough estimate, using Tesla’s own calculator, a good-sized family home would cost around 70,000 dollars to install an 8.05 kW system before tax incentives. This quote is based on a home in Nashville, Texas, with a floor area of 2,500 feet 2 (232 m 2 ) and using an average monthly energy bill of 115 (this was the U.S. average in 2019, according to the EIA).
This, according to Tesla’s estimates, should be able to produce for this hypothetical home, somewhere in the order of 12,800 kWh/year, or roughly 100% of the building’s electrical energy consumption. You also get the added bonus (for additional cost) of energy storage with this system, which is a considerable advantage over some conventional domestic solar panel arrays.
If this estimate is accurate, that should provide a payback period (the time taken to recover your initial investment) of about 50 years, give or take. This will likely be closer to 40 years after tax incentives are factored in to reduce your initial capital outlay.
Another estimate for a 1,700 ft 2 (158m 2 ) roof in California with an electrical bill of 150 per month came in at 39,000 before incentives for a 6.13-kilowatt system. It should be noted that this quote was generated in 2022 and for a different state, so costs likely vary for that reason.
You should also remember that energy costs from the grid are likely to rise over time, so the true payback will likely be much shorter, ignoring any maintenance and cleaning costs of course.
We’ve chosen this square footage as it is about the average size of a new family home in the United States.
To put that into perspective, installing a similarly sized conventional solar panel array would cost around 26,000 before incentives. Using the same statistics as above would give you an equitable payback of between 15 and 22 years, depending on tax incentives.
However, remember that the estimated lifespan of conventional solar panels is also roughly 25 to 30 years, so you would probably need to replace the array after a few decades.
It should be noted, however, that such estimates should be taken with a pinch of salt. The final figures will likely vary widely depending on where your home is located if you were to actually order an installation.
This is especially the case for conventional solar panel installations and you are always advised to source several quotes from recommended installers before authorizing any work.
Any and all costs for such installations should also include any planning and design work required prior to the installation. This will not only ensure the costings are as accurate as possible but also discover if your existing roof is appropriate for such an installation.
The latter is less relevant for Tesla solar roofs, as these tend to be a direct replacement for your existing roof covering.
You should also note that costs are likely to vary over time as labor, consumable, and material costs will fluctuate, given the current economic climate. There may be other costs, too, such as various local authority planning requirements, where relevant.
Solar panels vs. Tesla solar roof: which one is better?
Generally speaking, on a per watt average cost, Tesla’s Solar Roof is actually pretty reasonable, all things considered. According to some estimates, in the United States, Tesla’s come in at around 1.80 per watt. Traditional solar PV panels tend to cost around 3.00 per watt.
However, any direct comparison between the two is complicated by a few factors. The first is that Tesla’s Solar Roof is not just some PV solar panels but actually a new roof and some PV panels in one package.
Traditional solar PV panels are where your roof can handle it, simply mounted to an existing roof without needing to replace it. So, in order to provide a fair comparison, we’ll need to do a like-for-like summing up.
In today’s world, where environmental concerns are at the forefront, sustainable living has become more than just a trend—it’s a necessity.
As people strive to reduce their carbon footprint and create a greener future, homes play a crucial role. By incorporating sustainable features into their homes, individuals can minimize energy consumption, reduce waste, and promote a healthier environment. In this article, we will explore five sustainable home features that everyone should consider when building a new home or renovating an existing one.
Smart Home Technology
Integrating Smart home technology can significantly enhance the sustainability of your home. Smart thermostats, for instance, learn your temperature preferences and adjust heating and cooling accordingly, optimizing energy usage. They can also be remotely controlled through mobile apps, allowing you to manage energy consumption even when you’re away.
Smart lighting systems utilize sensors and timers to automatically turn off lights when rooms are unoccupied, reducing unnecessary electricity usage. Additionally, Smart home systems can help monitor and manage energy usage from various appliances, enabling you to make informed decisions about energy conservation.
Energy Star Appliances
Energy-efficient appliances are a simple yet impactful way to make homes more sustainable. Traditional appliances consume a significant amount of energy, contributing to greenhouse gas emissions. However, by opting for energy-efficient models, individuals can reduce energy consumption and lower their utility bills.
Look for appliances with the ENERGY STAR label, as it indicates that they meet or exceed the energy efficiency standards set by the Environmental Protection Agency (EPA). Whether it’s refrigerators, washing machines, dishwashers, or water heaters, replacing old, energy-guzzling appliances with efficient alternatives is a practical step toward a sustainable home
Efficient Insulation Triple Pane Windows
Proper insulation and energy-efficient Windows play a critical role in maintaining a comfortable indoor environment while reducing energy consumption. Effective insulation prevents heat transfer, ensuring homes stay warm in winter and cool in summer. By minimizing the need for heating and cooling systems, which are significant energy consumers, homeowners can improve energy efficiency and reduce utility costs.
Energy-efficient Windows, featuring multiple panes (we recommend triple pane for best results), low-emissivity coatings, and insulating frames, help reduce heat transfer and air leakage. Investing in quality insulation and Windows enhances energy efficiency, provides financial savings, and improves overall comfort within the home.
High-Efficiency HVAC Systems
Heating, ventilation, and air conditioning (HVAC) systems are significant contributors to energy consumption in homes. Upgrading to high-efficiency HVAC systems can make a substantial difference in both energy usage and comfort. These systems are designed to deliver precise heating and cooling while minimizing wasted energy.
Look for HVAC units with high Seasonal Energy Efficiency Ratios (SEER) and Annual Fuel Utilization Efficiency (AFUE) ratings. Advanced features such as zoned heating and cooling, Smart thermostats, and variable-speed compressors provide optimal temperature control and energy savings. Investing in high-efficiency HVAC systems ensures a sustainable and luxurious indoor climate for your home.
Green Roofs
Transform your rooftop into a thriving green space with a green roof installation. Green roofs consist of a layer of vegetation, soil, and drainage systems that cover the roof surface. They provide numerous benefits, including improved insulation, reduced stormwater runoff, and enhanced biodiversity.
Green roofs act as natural insulators, reducing the energy needed to heat or cool your home. They also absorb rainwater, minimizing strain on drainage systems and reducing the risk of flooding. Additionally, green roofs create a habitat for birds, insects, and other wildlife, contributing to local ecosystem preservation. Embrace the sophistication and ecological advantages of green roofs to make a sustainable statement with your home.
Solar Panels Tesla Powerwalls
Solar panels have revolutionized the way we generate clean energy. By harnessing the power of the sun, solar panels provide a renewable energy source for your home. For a more sophisticated approach, consider pairing solar panels with Tesla Powerwalls. These advanced battery storage systems allow you to store excess solar energy generated during the day and use it during peak demand or at night when the sun is not shining.
Tesla Powerwalls provide a reliable and efficient way to maximize your solar energy usage, reduce reliance on the grid, and ensure a continuous power supply, even during power outages.
Geothermal Heating Cooling
Geothermal heating and cooling is a sophisticated sustainable home feature that taps into the earth’s natural heat to provide year-round comfort. By utilizing a ground loop system, geothermal systems transfer heat energy, offering energy-efficient heating, cooling, and hot water. Benefits include:
- Energy Efficiency: Geothermal systems use significantly less electricity than traditional HVAC systems, resulting in cost savings and reduced environmental impact.
- Consistent Comfort: With stable underground temperatures, geothermal systems provide consistent warmth in winter and cooling in summer, eliminating temperature fluctuations and drafts.
- Durability and Low Maintenance: Geothermal systems have a long lifespan and require minimal maintenance, offering reliability and quiet operation.
- Hot Water Supply: Geothermal systems can also provide hot water through a desuperheater, further reducing energy consumption and costs.
While the initial installation cost may be higher, long-term energy savings and environmental benefits make geothermal systems a sustainable choice. Federal and state incentives can help offset the upfront investment. Embrace geothermal heating and cooling to minimize your carbon footprint and enjoy efficient, eco-friendly home comfort.
Building A Greener Future
Creating a sustainable home is not only beneficial for the environment but also for those seeking to reduce their ecological footprint and save on energy costs. By incorporating even one or a few of these sustainable features into your home, you can make a significant contribution to a greener future.
Not only will you enjoy the satisfaction of knowing you’re reducing your environmental impact, but you’ll also reap the rewards of reduced energy consumption and long-term savings.

How Do Tesla Solar Roofs Work? Are They Worth the Investment?
Tesla prides itself on its dedication to a cleaner planet through their innovations, but will their new solar shingles mean a brighter future as well?
Oct. 21 2020, Updated 5:09 p.m. ET
In April 2016, the Tesla company revealed that they were working on something new. Up until that point, their FOCUS had always been on electric vehicles, which had earned them quite a reputation among environmentalists and financial experts. They rose success and worldwide fame, and started looking to make use of the world’s greatest renewable resource by creating Tesla-brand solar panels.
Tesla hyped the panels up significantly but two years later, people still weren’t convinced. They had claimed that their solar roof panels were designed to be durable and effective, but thus far, very few of them had been installed. It was hard to gauge how durable or how effective they really were. After nearly four years of development, however, it seems Tesla’s Solar Roof V3 is finally beginning to meet expectations.
What is the Tesla solar roof?
Tesla and its subsidiary, SolarCity, designed their solar roof product to look like a traditional roof. The only difference is the shingles, which are photovoltaic, which means they generate solar power in the same way that traditional solar panels do. The idea was to make a solar roof that was not only effective but aesthetically pleasing. Installing one of these solar roofs replaces an existing roof with a combination of active and inactive shingles.
Active shingles contain solar cells that absorb solar energy to produce energy for your home. The inactive ones function just like regular shingles. They do not produce any energy but keep out water, hail, rain, and other inclement weather in the same way that normal shingles do. Tesla’s solar roof V3 shingles come with a 150-year weatherization warranty. They can withstand 166-mile-per-hour winds and 1,75-inch hail. While it sounds impressive, though, the Tesla roof tiles do have weaknesses.
What are some of the downsides to Tesla’s solar roof?
Many of Tesla’s downsides are shared by other solar companies of the like. For instance, because Tesla panels usually need to be connected to a power grid, they will stop producing electricity during a power outage. This limits who and where a Tesla roof can be installed. If you live far off the grid and wish to install a Tesla roof, you may be out of luck.
Tesla also has a history of being unreliable when it comes to installing their solar roof products. Many who have ordered Tesla panels at the onset, still have not had them installed; some orders have even been canceled on Tesla’s end. Whether that is an effect of slow production or their struggles to invent a product that stands out from the competition, is not known.
How much does Tesla solar roof cost?
Tesla’s official pricing structure says that the active solar roof tiles cost about 2.85 per watt. Inactive shingles cost around 5.60 per square foot. However, these are not the only metrics to consider when determining the cost of installation. The actual total cost of a Tesla solar roof depends on several factors including the size of your home, needed energy output, location, and roof size.
For a 1,200 square foot home with an electric bill of about 150 per month, the estimated cost for a Tesla roof installation would come to approximately 24,412, with other factors potentially altering the final cost. Replacing roofing materials can amount to thousands of dollars, while federal tax credits for investing in solar power can bring the overall price down. Tesla predicts that a 6.2 KW roof can save upwards of 45,000 on electric bills over the course of a lifetime.
How does Tesla solar roof compare to solar panels?
Traditional 6.2 kW solar systems produce roughly around 10,180 kilowatt-hours (kWh) of electricity per year. This means that the average 25-year savings for a traditional solar system comes out to approximately 48,356.90 in a lifetime. That costs almost 4,000 more than Tesla will save you.
Not only that, traditional solar panels are far less invasive and do not necessitate an entire restructuring of one’s roof. Add to that the proven track record of many solar manufacturers as compared to the uncertainty of Tesla’s unproven system, and you have a bit of a quandary on your hands.
Are Tesla tiles worth it?
Unless you are already planning on replacing your roof and investing in solar, it may be prudent to consider alternatives to Tesla solar roof. In the end, the best way to enter into any serious investment is to do your research. Getting quotes from multiple solar providers will allow you to compare installation prices, energy outputs, lifetime savings, and in many cases, monthly costs.
Tesla Solar Roof (v3): We installed one and here’s how it went.
Weddle Sons Inc. is the first roofing company to be certified to install Tesla’s Solar Roof in the Midwest. In February 2020, we traveled to Tesla’s headquarters in California and spent a week in training. Before we began installing a brand new product on anyone’s home, we decided to start in our own backyard and did the first install on Allyn Weddle’s (our President) home.
“It was awesome to get to work all together. our team does amazing work and this project was no different. I’m excited to see how Solar Roof can be used on other homes and how it performs on mine first! I wanted to make sure this lives up to the hype. When I recommend a product to someone, it’s typically because I’ve used it on my own home. I definitely wanted to continue that trend!”
Solar Roof is unique from other solar panel options on the market. It’s made out of tempered glass with the solar active panels having built in photovoltaic cells. It incorporates the solar active components into a sleek and beautifully designed tile that replaces your current roof.
First and foremost, its tough! During the installation we spent many hours walking, kneeling, and sometimes, crawling all over the tiles. In the entire installation process, we only broke three tiles and even then it was because someone (he shall not be named) dropped a hammer.
How durable is Solar Roof?
Solar Roof is impact resistant to hail, which is enormously important in the midwest. It carries a 130mph wind rating and the best fire resistant rating on the market.
Installing a Solar Roof and a traditional roof have a few things in common. A few things….
But mostly, the process is incredibly unique. First, brackets need to be installed onto the roof deck. carefully measured and nailed down. Then the tiles are snapped in place on top of the brackets. The panels are wired to each other and eventually tied into the house’s electrical system. Since each roof is evaluated before installation, Solar Roof is delivered with the exact amount of tiles, both solar active tiles and non active tiles.
Not each tile is solar capable. Why is this?
- The more solar active tiles you have, the more energy you can produce, but the solar active tiles are more expensive to make.
- Solar active tiles don’t interact well with metal. Some of the tiles that were placed right next to the valleys (all metal on Solar Roof) needed to be inactive tiles for the electrical system to work properly.
Our Thoughts On Solar Roof?
We’re excited about this product. It looks phenomenal on any roof! There are definite limitations though. Not every roof is a good candidate because of roof complexity and sun exposure. It’s important to keep those factors in mind. A simple roof line that’s in direct sunlight most of the day is ideal.
Time is also a factor. A traditional roof, in many cases, will take one or two days to replace. A solar roof, because of the complexity of the installation process, can take 4-6 days, depending on the roof.
All in all, Solar Roof is a great option for many who are looking to gain freedom from the grid and gain some energy independence. The technology has come a long way and we’re excited to be on the front line of installations and being able to offer this product to our customers in the Midwest market.

New TESLA photovoltaic tiles
Elon Musk is suggesting that the new version of Tesla’s solar shingles will be even cheaper and will be roughly equivalent to the cost of a shingle roof including the electricity bill, which the solar roof will cut through solar power generation.
When Tesla launched its solar shingles in 2017, the automaker said it would start production and installation in 2018. However, the launch proved to be much slower and installations were limited to the homes of some executives and some customers. Tesla later delayed production until 2019.
CEO Elon Musk said he needs to make some changes to the product to make sure it will last for 30 years. At Tesla’s 2019 shareholders’ meeting, Musk said he is completing a third version of the Tesla solar roof: We are about to complete version 3 of the solar roof, this is actually a rather difficult technology problem, to have an integrated solar cell. with a tile, look good and last for 30 years. The CEO explained that they had a hard time running accelerated tests on the roof, but now they feel safer.
With the third version, Musk seems confident that Tesla can lower the cost to a level of great affordability: I am very excited about the version 3 of the solar roof, this is one of the cheapest roofs available. That way you can have a great roof with a better economy than a normal roof and with a fairly cheap bill
When he launched the first product, Tesla said that the typical homeowner can expect to pay 21.85 per square foot for a solar roof. It’s a fairly expensive product even though it comes with a lifetime home warranty and a guaranteed 30-year power generation. In the new version, Tesla has estimated that its solar roof will be cheaper than a similarly styled non-solar tile roof and virtually pays for itself through electricity savings.
As for installation times, Tesla said it should take about the same time to install a tile roof, which is typically 5-7 days. Earlier this year, we reported that Tesla Solar Roof installation still took around 2 weeks. The installation time must decrease to increase the distribution.
The tiles have an interesting appearance with different surface treatments, the color is dark typical of monocrystalline silicon. The fixing system from an image of the positioning phases seems quite simple but the technical specifications have not yet been disclosed.
If Tesla manages to improve production costs, and the declared specifications, primarily cost and duration, prove to be true, there will be a significant technological leap in the field of electricity production and the current photovoltaic systems will be obsolete.

Salve Elisa, si in effetti sarebbe interessante avere il dettaglio dei collegamenti tra tegole e impianto ma purtroppo non abbiamo mai trovato niente al riguardo, non ci risulta che Tesla abbia pubblicato questo tipo di informazioni tecniche.
elisa.leone99@iCloud.com
Quando saranno disponibili i disegni del particolare costruttivo con la stratigrafia del tetto che mette in evidenza gli agganci elettrici di ogni singola tegola? Sto facendo la tesi su queste tegole e senza neanche un disegno è difficile
