We have two chimneys and a huge oak tree they had to work around, but they still managed to eke 2.4 kW out of a north-facing city inside rowhouse flat roof. 20 year lease and then you either extend for another 10 years, buy it at whatever nominal market value the system has at that point, or they come and take it away and fix your roof (no charge).
Sure, I wouldn't mind taking a look at it. There's a house 4 blocks or so from here with a big sign and Solar City pamphlets. I did sign a one year deal with Reliant so that Pepco would at least lose some of my business. I know I have the right exposure because at about 1pm the sun shines DIRECTLY into my skylight and makes my bedroom a furnace.
Also, my A/C compressor is on the roof, I wonder if that causes problems.
