Dow PowerHouse Solar Shingles

Dow Solar's PowerHouse Solar Shingles should appeal to homeowners interested in producing renewable energy without having to radically change what their roof looks like. Made from copper, gallium, selenide, and indium, these solar shingles are meant to be easily installed, and to last for years. They can even be walked on, or dropped from up to two stories.

The system comes with an AC/DC converter and a home energy monitor designed to track how much power the shingles are producing, as well as how much is being used.
