Solar Roof which was first unveiled back in October 2016 is the first of its kind. The product which is designed to resemble a normal roof, but contains hundreds of hidden solar panels within the tiles removes the need for panels bolted onto the exterior of the roof.
The only real downside with Solar Roof is that currently it is expensive. For example, to add Solar Roof to a 2,000 square foot home would cost in the region of $50,000. However, like with most technology, the pricing is likely to come down pretty quickly in the months and years to come.
