Additional Costs And Upgrades
Depending on the current infrastructure present in your home, Tesla mentions that it may be necessary to perform additional upgrades during installation. This includes services such as extra electrical work or installation of a Solar Roof on a shed or deck. Prices are quoted directly to you upon inspection, but it is important to note that they are not included in the Solar Roof calculator estimate.
How Do Gafs Timberline Solar Shingles Perform
GAF doesnt provide any official specifications on their website for their solar shingles.
However, some versions of the products data sheet have been floating around online, and it seems as though each shingle has a power rating of 45 watts. So, in order to install a 6 kilowatt GAF solar roof system, you would need around 134 shingles, whereas you would need just 17 traditional 370-watt solar panels.

Less Energy Loss Due To Shading
Conventional solar panels have the individual cells wired in series so when a part of the solar panel is shaded it can have a significant effect on the level of power output. By configuring the solar cells in shingles, they can be wired in groups and configured in parallel which significantly reduces the losses caused by shading.
Current flow comparison
Below are some examples of shading and losses for a conventional solar panel and a Solaria Power XT shingled panel. The Solaria Power XT panels have greater performance except for the vertical shading example.
Outdoor shade testing over a 70-day period has shown that the Solaria Power XT shingle solar panel performs between 37 to 45% better than conventional solar panel designs.
Solar Shingles For Saleaverage Cost
Solar shingles cost per square foot can vary widely between different brands, and your overall solar panel shingles cost will depend on the total square footage, typical energy needs, and your choice of manufacturer and installer.
The average solar shingles price for your roof could be in the range of $15,000 to $20,000, but if you choose a highly sophisticated system, such as Tesla solar roof shingles, it could cost you as much as $70,000 or more.
You should request the brands of your choice to provide you a free quote, and evaluate their features and unique selling propositions in the context of your budgetary limits in order to make the right decision.

Pros Of Solar Shingles
- More aesthetically appealing and sleeker compared to the bulky and somewhat unattractive traditional solar panels, and can blend in more easily with your existing roof design
- If you are building a new home or replacing your roof, solar power shingles could prove to be more cost-effective because you would save on the traditional roofing material and labor
- Solar panel shingles can usually be removed and reinstalled in a situation where you have to move your home
What Roof Type Is Best For Solar Panels
Solar panels can be installed on almost any roof style with a few exceptions. The roof on your home, garage, shed, or barn could all be potential candidates for roof-mounted solar panels. Whether its a gable, hip, or a combination roof, a solar installer can figure out the best way to mount panels.
Solar engineers and installers can split up solar arrays into multiple sections to follow the rooflines and work around roof components, such as skylights, box vents, or pipe boots.

Do Solar Shingles Perform Better Than Regular Solar Panels
A 6 kW solar shingle system will produce less electricity than a conventional 6 kW solar panel system. Why? Because they are installed right against your roof, just like regular shingles. This means they arent at the ideal angle for generating electricity, whereas solar panels are mounted on racking equipment that optimizes the tilt and angle of the panels to generate the most electricity possible.
Plus, solar shingles tend to get hotter than solar panels because there is no airflow between your roof and the back of the shingle. Believe it or not, the hotter solar cells are, the less electricity they can produce. So, between the installation angle being dictated by the slope of your roof and the higher likelihood of higher surface temperatures, solar shingles will operate less efficiently than solar panels.
Are Solar Shingles Efficient
Because a solar panel roof is built to the slope of your existing roof, it can be less efficient than solar panels. Solar installers can modify standard solar panels to different angles to make the panels most efficient for your home. You can also use a solar battery to save solar energy for off-peak times.

Scenario : Youre Interested In Solar
Storage is becoming increasingly popular to install with your solar panels depending on where you live. Especially if you live in an area that experiences frequent blackouts, you might want to pair storage with your solar installation to provide backup power. Or, if you dont live in an area with net metering, you might want to store the excess energy that your solar system produces during the day to use at night. Whatever your reason, the Tesla Solar Roof could make financial sense for you, depending on how much storage you need.
In our example, lets say you experience frequent blackouts at your home in California and want a storage system to provide backup power. While youd probably only need one battery to provide backup for all of your essential appliances, if you want to power more appliances or experience long blackouts, maybe youre looking to purchase two. With your Tesla Solar Roof, you can only install a Tesla Powerwall, which provides 13.5 kWh of backup energy and varies in cost depending on how many you add. Thus, well use this storage option in our Tesla Solar Roof estimate.
Cost Comparison Between The Different Types Of Solar Shingles Available On The Canadian Market
The Tesla Solar Roof is not a new concept. Other manufacturers have already attempted the production of solar shingles some have failed, and others are still on the market. One of the products from Dow Chemicals Powerhouse Solar System only lasted five years at the time it was the product of choice, but the company end up going bankrupt.
Other companies are continuing to produce and install solar shingles. But it is difficult to find the costs associated with it. It is important to note that the companies listed incorporate solar shingles and tiles with traditional materials, while Teslas solar roof tiles are designed to cover the entire roof or even replace it. But Teslas competitors are demanding that a large part of the roof be covered with normal shingles in addition to the price of their systems.
1. Dow Chemical
Even if the company is no longer in business, it is worth looking at it because of cost information. Their Powerhouse system did not cover the entire roof it came in super shingles that fit well with traditional shingles. Installing 350 Powerhouse shingles would cost more than $ 20,000 and reduce electricity consumption by 40-60%. In a Dow press release, it was announced that for an additional expense of $ 27,480 above the cost of a traditional roof, you could collect $ 58,640 in energy savings over 25 years, and similarly increase the value of your home by $ 33,000 .

How To Get Your Roof Ready For Solar Panels
Roof-mounted solar panels are a great way to harness the power of the sun and save on your home energy bills. A roof offers an ideal location for solar panels as it typically gets a great deal of sun exposure, which is good for maximizing your home solar energy production. Even on cloudy days, high-efficiency solar panels installed on your roof can generate power in low light as they capture direct and indirect sunlight.
What Sets Timberline Solar Shingles Apart From Teslas Existing Shingles
The very first time the world heard about solar shingles was when Tesla released its signature solar roofing materials that can generate enormous wattage on the same level as standard solar panels. However, owning one of Teslas coveted easy-blend and appealing solar shingle systems cost a fortune.
After their exhibit on CES 2022, GAF plans to take a bigger spot on the solar shingle pie with its own GAF Timberline Solar Singles. Their biggest difference: you can nail a GAF solar shingle, making its installation faster and much more affordable than Teslas existing ones.
Here are their major differences from each other.

Solar Shingles Cost Compared To A Conventional Roof Replacement Cost
The cost of a solar roof is going to seem a bit high compared to a traditional roof replacement or a conventional solar installation, but it’s important to keep in mind that a solar roof installation includes the value of both a roofing material and a solar panel system.
When you install a Tesla solar roof, you install both active and inactive shingles. The active shingles convert sunlight into energy for your home, while the inactive shingles just act as regular shingles.
Based on Teslas estimates, the solar shingles come to $1.80 per watt. This is lower than the average cost of traditional solar panels, which is around $3.00 per watt.
The cost of the inactive shingles depends on the complexity of your roof, so it will cost between $15.30 and $21.27 per square foot of inactive Tesla shingles. This is higher than the average for traditional asphalt shingles, which is somewhere between $3.50 to $5.50.
Based on these quotes, a traditional roof replacement would cost around $9,350 for a 1,700 square foot roof and a conventional 10 kW solar system would be $30,000, before incentives. That brings you a grand total of $39,350. The entire Tesla solar roof for the same home, assuming it has a simple roof complexity, would come out to around $44,010.
Thats not too much higher than a conventional roof replacement and solar panel system, but thats assuming the lowest price Tesla will give you for roofing materials.
Solar Shingle Power Output
Depending on the brand and type of shingle you purchase, power generated by your solar shingles will vary. Most shingles produce between 13 and 63 watts. According to some estimates, 350 tiles can reduce the average utility bill by 40 to 70 percent. All systems require an energy inverter kit to harness the power captured by the cells, power systems, dive deeper into technical details and teach you more about solar energy.

Tesla Solar Roof Shinglecons
- Compared to almost every other brand on the market, Tesla solar power shingles will have a significantly higher cost at anywhere between $50,000 and $100,000 for most homes, including the price of PV tiles and Powerwall batteries
- While traditional installations may take about three days or less, a Tesla solar roof installation could take up to two weeks
- If you are using an electric car, and plan to recharge it with your Tesla solar roof installation, you will require an additional one or two Powerwall batteries
- Tesla roof installation will require a complete removal of your existing roof, which could be an unsavory prospect if your roof is still in good condition and doesnt really need a replacement
Tesla solar shingles cost at present is $21.35 per square foot. This means, if you are looking to install a Tesla solar roof on a 3,000 square foot home, it could cost you somewhere around $60,000.

According to Wood Mackenzie, customer acquisition costs usually make up 23% of the total cost of a residential solar system, so saving here could be key.
GAF Energy also touts the fact that it assembles and partially manufactures its shingles at its facility in San Jose, California. While the company imports its PV cells from Thailand, it believes that having some domestic manufacturing is advantageous.
“What that allows us to do is take improvements in our product from the lab and get them to instantiate in the product very, very quickly,” DeBono says. Alternately, teams would have to fly overseas to execute changes. “And what you see is changes to your product take quarters and years, literally, whereas here it takes hours and days.”

Streamlined Installation Should Cut Costs Over Competing Solar Roofs
by Tim De Chant – Jan 4, 2022 7:17 pm UTC
A new solar technology introduced yesterday at CES could bring power-producing roofs mainstream by relying on an old building materialnails.
For years, homeowners who wanted solar power have stripped their old roofs of shingles, added new ones, and then slapped large solar panels on top using sturdy frames. Its a model that works well, but it also creates a two-step process that engineers have been striving to simplify.
Plenty of companies have offered their own take on solar roofs, but so far, theyve remained niche products. GAF Energy is hoping to change that with the Timberline Solar Energy Shingle that looks strikingly like typical asphalt shingles. But their key feature isnt so much that they emulate the look of asphalt shingles, but that theyre installed in nearly the same way. Roofers can slap the flexible sheets down and nail the top strip to the roof, just like they do for traditional roofs.
By relying on the shingle installation process, GAF Energy is counting on the scale of the roofing industry to make solar more accessible. The roofing ecosystem is 2030 times larger than solar. In the United States, 200,000300,000 people get a new solar system each year. Over 5 million get a new roof, Martin DeBono, CEO of GAF Energy, told Ars. Our innovation is you now have a nailable solar roof, which fits the way that the majority of roofs are installed.

Cost To Install Solar Shingles
The cost of a solar shingle system varies greatly with your homes square footage, energy needs, shingle manufacturer and the solar installer. Some systems, such as RGS Powerhouse, may only run $15,000, whereas Teslas solar roof can cost upward of $70,000. We recommend requesting a free quote to get an accurate estimate for how much it would cost you to install solar tiles.
Efficiency Of The Tesla Solar Roof
One factor to consider when making a cost comparison between installing new solar panels and installing a new Tesla Solar Roof is efficiency. Tesla has not released data on the efficiency of its solar shingles, but EnergySage estimates that typical solar shingle brands range from 14 to 18 percent efficiency, whereas most solar panels are 22 to 23 percent efficient. Its important to keep this in mind when deciding if the Tesla Solar Roof is worth it for you because your overall return on investment will likely be lower than if you install new solar panels.

How Long Will Gaf Solar Shingles Last Are They Durable
GAF Energy offers a 25-year warranty on their solar shingles. According to the warranty, GAF covers their shingles for 25 years against manufacturing defects that cause roof leaks, and offers a 15-year wind coverage warranty for wind speeds up to 130 miles per hour.
They also include a 25-year solar production output warranty that states the shingles will operate at 84.8% of their original rated output at the end of 25 years. Most solar panels will operate closer to 86% of their original rated output, meaning they would generate a little more electricity over time than the solar shingles, but not by much.
Since GAF hasnt released a specification sheet for these shingles yet, we dont have all the information wed like to, such as the hail rating, but we do know they are the first product to receive a UL7103 certification. This safety certification was designed specifically for ‘building integrated photovoltaics’ , or in other words, solar shingles.
