Tesla is also opening up the installation of the Solar Roof to traditional roofing companies to increase its installation capacity. Just build one of the new tiles and you get more solar generation, fewer points of failure, and easier, faster, and cheaper manufacturing. No more connecting the three panels with internal wiring or physical connectors. No more wiring up MC connector ends to each of the three tiles. Granted, they are larger, but they are also just a more efficient design on a number of levels.įinally, getting rid of the seams between the panels makes it easier for Tesla to produce the panels at its Gigafactory 2 in Buffalo. We’ll have to wait and see what each of the new v3 tiles produces, but it’s clear the output is much higher. That means a more sealed roof and more PV generation from each of the new tiles. Eliminating the need to create the bricks of 3 manually connected photovoltaic tiles gets rid of the seams between each of the individual tiles. That translates to less potential points of failure and a much simpler, faster, cheaper installation.īut that’s not all folks. The increase in size not only reduces the number of roof tile units that must be installed, it eliminates a large percentage of the internal non value add components in each of the PV Modules in version 2 of the Solar Roof.
That not only effectively replaces a single pre-wired PV Module from version 2 of the Solar Roof, it increases the width of the panels significantly. The new tiles are significantly larger, at 45″ long by 15″ wide. Each PV Module required hardware to link the three individual tiles together, wiring to connect them and waterproofing to ensure a good seal.Ī Solar Roof version 2 tile. These were shipped from the factory in bricks of three pre-wired tiles called PV Modules. Tesla previously used roof tiles that were approximately 14″ long by 9″ wide. These changes came about first and foremost thanks to the larger footprint of the new tiles themselves. Changed the coating that hides the solar cells to a more scalable technology.Reduced cost, enabled by the larger tiles.Reduced the number of steps in manufacturing, made possible by the larger tiles.

Dramatically reduced the number of parts and sub-assemblies required to install a Solar Roof by more than half, made possible by the larger tiles.Increase in tile power density for increased solar generation.Increase in tile size for faster installation, better protection, and increased solar generation.Vice president of technology at Tesla Drew Baglino said Tesla was aiming to improve the product essentially across the board, improving its cost, beauty and manufacturability of the tiles across the board.īy all accounts, version 3 of the Solar Roof delivers on that promise, delivering significant improvements including: Tesla’s objective in developing version 3 of its Solar Roof was to improve on the flaws identified in the earlier versions of the product.

Feel free to use my referral code ( ) to save $100 on a Tesla Solar Roof or Tesla Solar system for your home. Side note: I have a previous version of the Tesla Solar Roof on my house, installed in late 2019. Hop on in and we will give you a guided tour of Tesla’s new Solar Roof that Elon thinks has the potential to “grow like kelp on steroids.” With this new third iteration of the Solar Roof, Tesla has increased the energy density, cut the cost, increased the manufacturability, decreased the installation time, and reduced the warranty for its Solar Roof.
