Tesla Share Twitter Pinterest Email Energy Renewable Energy Fossil Fuels Tesla unveiled its solar roof tiles last fall with major fanfare and for good reason. The energy-generating roof tiles could make an entire roof a power station while also looking beautiful at the same time. The only downside was that the solar roof tiles were only attainable for people who were building a new home or installing a whole new roof. Homeowners wanting a way to add good-looking solar energy to just a section of their roof were out of luck unless they wanted to undertake some heavy renovations. Until now. Tesla quietly updated their website this past weekend to reveal an addition to their solar power portfolio: sleek, low-profile solar panels that can be added to any existing roof. The solar panels will be made by Panasonic at Tesla's Gigafactory 2 in Buffalo, New York exclusively for Tesla. The solar panels are made to integrate with the company's Powerwall energy storage units for a round-the-clock clean energy supply. © Tesla The 325-watt solar panels have no visible mounting hardware and an integrated front skirt to make the panels as camouflaged and streamlined as possible. Tesla claims that these panels also exceed industry standards for durability and lifespan. Elecktrek reports that the non-exclusive 325-watt module that Panasonic has on the market has an efficiency rate of 21.67% and these new panels are likely similar. Tesla will start producing the solar panels this summer and will begin using them exclusively for all residential solar installations going forward in replacement of any other third party solar panels. While production hasn't started yet, and there's no information yet on pricing, you can already request a custom quote for your home on the website.
