This Old House magazine took a look at solar shingles back in 2008, writing “These systems — called ‘building-integrated photovoltaics,’ or BIPVs — combine solar cells with slate, metal, fiber-cement, even asphalt roofing. Electricity is generated when the sun strikes a semiconductor layer, typically crystalline silicon, laminated to the shingle's surface. One shingle by itself doesn't produce a whole lot of power … but harness hundreds of square feet of them together, and you can generate enough electricity to power a whole house.”
