Like solar tiles they have a sleek modern look that is in stark contrast to the comparatively clunky looking rack mounted solar panels.
The result is that tesla s solar roof will cost nearly 25 000 more than installing solar panels and yet will only deliver 77 percent as much solar electricity due to it being a smaller system size.
Solar panels are installed on a finished roof.
