Interesting, at least for DC residents:

SolarCity®, already the largest solar service provider in the U.S. with 1,000 employees and more than 10,000 projects completed or underway, is expanding its operations to the East Coast. The company has acquired Clean Currents Solar, the solar installation division of leading Mid-Atlantic based independent green energy company Clean Currents LLC, and will serve Maryland and the District of Columbia from its new operations center in Silver Spring.

I may look into this, although I’m pretty sure my house, with a rather nice tree looming over it, isn’t set up for solar.
