All you can do is invite them to survey your place.
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.
