Tesla is launching a new solar roof tile with greater efficiency and higher power capacity. It comes as Tesla is trying to make its solar products mainstream.
The product has been widely recognized for its beautiful design. It undeniably has significant advantages over regular solar panels, with the ability to penetrate markets like new houses and homes that need a roof replacement relatively soon.
However, it has been hard to bring it to market.
Tesla has had issues testing for longevity, with prices fluctuating widely as the company realized the difficulties of create a streamlined product for such different things as roofs.
As we previously reported,Tesla significantly increased the price of the solar roof tilesearlier this year, after introducing a new "roof complexity factor."
But the company claimed that the demand for the solar roof was still strong after this price increase, and that installations are accelerating.
Now we learn that Tesla is making a significant upgrade to its solar roof with a new, more powerful, solar tile.
Electrek has obtained a datasheet for the new solar tile that Tesla has started to include in solar roofs designed for customers.
Tesla previously used its “SR60T1” tile, with a 58.5-watt capacity, in solar roof designs.
Now the company is now producing quotes and starting installations with a new “SR72T1” solar tile.
With more efficient solar cells, Tesla managed to maintain the same tile size with a 22% increase in max power output.
In a solar roof installations, Tesla installs tiles with solar power and some without. The company tries to optimize each roof by installing the tiles with solar cells where they would be more efficient.
From the angle of the ground, the solar tiles and non-solar tiles look the same. Using fewer solar tiles could simplify the installation process, since it will require fewer electrical connections between tiles.
Interestingly, the new tile datasheet also mentions that Tesla can install the solar tiles over existing roofs.
Here’s the datasheet for Tesla’s new SR72T1 solar tile:
As we recently reported, Tesla is also trying to accelerate the adoption of its solar roof tiles by standardizing the product and having independent roofing companies install them.
Tesla is also pushing to get more solar roof orders.

Since 2017, Roofit.solar has been offering Europe a solution similar to Tesla solar roofs. The company earned the Solution for the Future 2020 award for its seamless 2-in-1 solar roof that can be found on more than 100 roofs around Europe while its modular steel roof tiles and click-roof panels are still under development but coming soon.
In 2017, the first Roofit.solar roofs were installed in Estonia by Tallinn-based company Roofit.solar Energy OÜ. The company''s 2-in-1 product—a metal roof with integrated solar panels—looks like traditional steel roofs and is as powerful as conventional solar panels.
Founder and CEO of Roofit.solar, Andri Jagomägi aimed to produce more affordable solar roofs than what could be found on the market, such as the solar roof by Tesla. Today, there are more than 100 Roofit.solar roofs in Estonia, Germany, Austria, Denmark, Poland, Sweden, Norway, Latvia and Kenya.
ArchiExpo e-Magazine: How are your solar panels produced? Is this different from how other companies produce their solar panels?
Andri Jagomägi: Roofit.solar modules represent building integrated photovoltaic (BIPV) construction elements that replace the conventional roofing materials, while electricity is produced in a photovoltaic layer integrated into the metal sheet. While on-roof traditional solar panels are bulky and unsightly, Roofit.solar modules go much further.Each individual Roofit.solar panel is constructed of a layer of silicon cells, glass, and a metal profile. For maximum effect, the panels are grouped together into "arrays" (series connection).During production we use black materials to mask shiny parts of the solar panel, which creates a nice, homogeneous black color that flawlessly blends into the metal, making the solar parts of the roof almost invisible.
Another feature that distinguishes our products from regular solar panels is high mechanical load resistance because of the metal back sheet. The metal back sheet is stronger than the plastic one usually used in standard solar modules. In addition, metal lasts longer and protects the photovoltaic layer from damage. Our metal sheets have Polyurethane coating (Pural) that has superior resistance to corrosion, abrasion, and chemical exposure. We also use monocrystalline cells that are more efficient than thin-film solar cells, used by other similar BIPV metal roof producers.
The difference between our modules and conventional solar panels is that we offer a 2-in-1 product that consists of the solar panel and the roofing material at the same time. In addition, our novel solution makes it possible to harvest solar energy from the roofs and facades, where normal solar panels are not architecturally suitable (i.e. historical buildings).
ArchiExpo e-Magazine: Nothing is all black or white, as we know, so what are the current challenges faced by solar energy?
Andri Jagomägi: Though the cost of solar panels has decreased over the years, it''s still an expensive investment and not accessible to everyone. This is one of the key challenges globally. Another challenge is that in order to keep up with the booming solar market, modern technical requirements must be met, meaning that companies have to constantly update their production line in order to have efficient and competitive products. This is connected to huge expenses general, one of the main problems with solar power is the fact that energy production only takes place when the sun is shining. Large storage systems need to be developed to provide a constant and reliable source of electricity when the sun isn’t shining at night or when the weather is bad.
ArchiExpo e-Magazine: Most, if not all, solar panels need direct sunlight or they aren''t able to obtain the energy. How do your solar roofs work? Are they only fitting for homes in certain climates?
ArchiExpo e-Magazine: What is the lifespan of your solar roofs and what happens to them once they''re no longer viable? Are they able to be recycled and reworked?
