The head of Tesla Motors Ilon Mask said that the solar roofs of Solar City, generating energy for the house, will be cheaper than conventional roofs both during the installation phase and during operation. Immediately after the meeting, rave reviews of the results of the event appeared on the web. No wonder, because if a roof that is capable of generating energy costs less than a conventional roof.
In August 2017, the roofs began to be installed. True, initially they began to receive employees of the company itself, and not third-party customers. All the rest had to wait, and this anticipation took place in an atmosphere of impatience.
This system works best in regions where there is more sunlight, which is quite logical.
Another interesting point is that this project is realized on its own, without state subsidies. In any case, Ilon Mask states this. He also says that the developed tile is much lighter than similar elements created by traditional technology.
