It appears the last thread was Sam's solar thread from 2014. So I'll start a new one for myself. A few homes in my neighborhood have gone solar and that got me a bit interested, but I was lazy and didn't followup on it. Then two friends, one a neighbor and one a coworker, told me they're going solar and both on contract. So I took advantage of their research to save myself the effort -- because I didn't have the time currently to properly dig into the topic myself. A big help is EnergySage.com. It's a consumer education site and also a sales aggregation site. You create an account, enter your info, and companies give online bids. You can talk online, research their solutions, and go from there. It's not the end all, but it's truly useful. I did some research, talked with friends and neighbors, made a spreadsheet (because you can't properly research any home upgrade without a spreadsheet). I've got an unobstructed, south-facing roof. It appears I can build a system that will provide 100% of the electrical power I need, on an annual average. Some months I'll over produce and sell to the utility; other months I'll underproduce and buy back. Over the year I should break even. Combined with the 30% federal tax credit, a system should pay for itself in about 12 years, assuming minor annual rate increases. State laws and utility regulations prevent me from overbuilding and selling back for a profit; a homeowner here wants a system that meets their needs and no larger. At this point I've got a great quote from a local installer. And I'm talking with Tesla Energy (formerly Solar City) to see if they can provide a good quote. I'm hoping to make a decision and be on contract this month, and be operational by early next year.
