This is one of the sales cars, probably making sales in the much friendlier Maryland market. Maryland is a big solar market--just look at the roofs--and I've spoken with reps at SolarCity who say they're expanding aggressively in that state. As a whole, SolarCity is at just over 6,000 employees. They'll be doubling that soon and we'll be seeing a lot of that on the East Coast.

I've tweeted at SolarCity to get an idea of how big their fleet is but haven't heard anything back yet. If anyone has any more information about this, please let me know!
Update as of Sept. 11: SolarCity got back to me on Twitter and said they have 75+ warehouses with each warehouse location averaging 55 vehicles. If my math is correct, that's 4,125 SolarCity vehicles!
