Now that's what I'm talking about. My house will need a new roof in five or ten years. I'm sure these are more expensive than a normal roof, but a lot less than a new roof <strong>and</strong> normal solar panels, plus you get all the benefits (tax breaks, cheaper electricity) from traditional solar panels. So, if I'm going to replace the roof anyways, might as well use these instead (assuming they work as planned and do replace standard shingles and the math works).
