Photovoltaic Roof Shingles

Billy Said:

why are photovoltaic shingles for a roof better then roofs made out of tar and other popular roofs?

We Answered:

They're not. Photovoltaic shingles are cosmetic enhancements only, (so you don't have to see the panels), and exponentially more expensive than phtovoltaic panels. They also follow the contour of the roof and cannot be adjusted to the correct angle for maximum sun exposure. Conventional panels on a good quality roof are the less expensive option, and will also prolong the life of the asphalt roof under it.

Clayton Said:

This question regards nanoparticle photovoltaic electricity. Is there sufficient raw material to mass produce?

We Answered:

There may be sufficient raw materials but that's not the issue at this point. Manufacturing costs are too high at this time to mass produce reliable nanoparticle photovoltaic electricity. It just plain costs too much and there isn't a good process ready for mass production right now.
