doing it yourself? otherwise there doesn't seem to be a return on investment. Some people are seriously getting duped by the solar companies out there and we're paying for it. That said, it is pretty dang impressive that you were able to self install your system. I've got a two story, 4200 sq ft house with tile roofing.... I don't think I'd want to go any where near that project lol I've looked into the usual suspects for installation but the numbers just don't work out.
