Seen from the ground Tesla´s Solar-Roof is indistinguishable from the usual clay or slate bricks, with the difference that they produce electricity. With a seamless design, each tile looks great up-close or from the street.
Tesla would like to continue to score with the design and durability of the solar system. In contrast to previous solar systems, the solar cells in the Tesla solution are integrated into the roof and literally merge with the tiles, which is a great advantage, especially for design purists. Besides, the cells should be more resistant and even withstand large hailstones of up to five centimeters. High wind speeds should also not harm the solar tiles. Tesla promises durability and power generation of at least 25 years.
According to Musk, the roof copes very well with snow and rain. It is slightly hydrophobic so that water, snow, and ice can slide down easily. The first snow test with the Tesla roof in Wisconsin was very satisfactory. To be able to produce electricity at all, the roof must be free of snow.
In the USA, the solar roof costs 235 US dollars per square meter if the roof is covered by 35% solar panels. However, a Powerwall, which is an electricity storage system has to be purchased for the equivalent of around $10 000.
If you have an electric car, the system is particularly appealing because it allows you to generate electricity yourself. Relieving the load on the power grid, which has to struggle with the ever-increasing demand for electricity due to the increasing number of electric cars, is a positive side effect.
Previous types of solar modules on roofs, as in the following picture just don’t look as good as Tesla’s unobtrusive panels, which you wouldn’t notice by looking at the roof.

The Tesla Solar-Roof is probably the best-looking solution for solar power production on your roof at the moment. It will be a few more months before it will be available worldwide, but I am confident that it will be well received.
