Also, what is your roof made of?
I'm in Baltimore, but I will check out the DC Solar Group to see if they have any recommendations for neighbors to the north.
I spoke briefly one company about doing this and it all sounded a little too good to be true. Know what I mean?
It means we didn't buy them -- the company we worked with still owns them, and after 20 years, I guess we'll have to replace them (or the owners of the house then will, if not us). There's a renewal option built into the lease, but I assume that by then, the technology will have changed enough that it's irrelevant.
In July and August 2011, our bills were $100 and $101. Last July and August, they were $64 and $50. We use less electricity the rest of the year, so the savings aren't quite as dramatic in other months, and we generate less in the winter, but still.
Our roof is white EPDM. The panels are actually not on the roof directly, though, they sit on beams that are attached to the parapets, which were reenforced by SolarCity's roofer as part of the installation.
Definitely want to try to find some input on any installer you're looking at, as with any other major house project.
