It is also "cheaper" than a common roof
The start of the pre-sale of Tesla new solar roof suffered a slight delay (the original plan was to start in April), but the expectation is so great that interested parties did not even notice it. The promises are several, however, there are two that stand well above the rest. First, Tesla says that in an average home it will be cheaper to install a sunroof than a normal one, and as if that were not enough, it offers lifetime warranty for its tiles.
Low cost electric cars, solar projects on remote islands, battery installations, gigantic factories ... Tesla not for. We recently talked about its progress on Ford and GM in terms of market value, and although it still has to deliver to Model 3, the monster of Elon Musk has not run out of air, quite the opposite. What's next on your list? Nothing less than the solar roof, officially presented to the public in October last year, next to version 2 of the Powerwall module. Already at that time Musk had suggested that the cost of installation for the sunroof would be lower than that of a conventional roof, and with the opening of its presale, we have a few more solid numbers.
The final cost will depend on the design of each home and the incentives / subsidies at the local level, but Tesla allocates an average of $ 24.5 per square foot traditional roof ($ 263.71 per square meter) versus $ 21.85 solar roof ($ 235.19 Per m2). In its calculations it includes materials, a Powerwall 2 module, installation and removal of the previous roof, but not the extraordinary expenses (taxes, permits, updates in the structure, etc.). The interesting thing is that the roof is not fully equipped with solar cells. In fact, that $ 21.85 comes with 35 percent coverage, although in most cases, Musk believes it will be 40 percent.
Example of cost that Tesla calculates for 1982 square feet with 70 percent coverage
Basically, the idea of Tesla is that if we introduce in the final calculation federal credits and the price of the energy generated, users will earn money by changing their ceilings within 30 years. That brings us to the subject of the guarantee: Tesla offers what it calls "infinite guarantee" for its tiles, equivalent to the life time of the house. Of course, this whole theory applies exclusively to the US market. Customers living in that country will be the first to receive the roofs (available in polished or textured design), while the rest of the world will have to wait until 2018, and make their own accounts.
