SOLAR SHINGLES

Solar Shingles are an option for roofing that performs the dual function of protection from the elements and generating power. Depending on the brand and type, the actual shingle type will last about 80 years give or take, which for you is likely a lifetime purchase. Maintenance is primarily on the battery system if you have one installed which is more electrician type work than roofer. Now, it doesn't seem possible to do the entire roof in Solar Shingles, just the center mass so the edges are done in something else of your choosing, I've seen a lot of people incorporate Concrete Shingles. Also, it doesn't appear to be possible to get a battery system if you're on the grid.

For all the stat info, I have the link to OkSolar cause they had the best layout of information to use to put against your power bill that averages for the different areas of the world and grades of Solar Shingles. With very generalized information about location, power production, and size if you paid for this system up front, you'd break even after 30 years of home ownership with the power bill savings. That doesn't include the federal subsidy you can get taken off the price however. It's a better investment for off gridders at the moment.

Cost Breakdown

Installation Cost: (1,200 sq ft of roof): $10,800 (without battery), $13,944 (with battery system)

Yearly Cost Savings (averaged over the different systems, grades and locations): $350
