solar panels fresno ca

How many solar panels on a given market? Where can I find this?
I need to know how many homes have solar panels Fresno, CA. Where can I find this information?
Before 2007, the California Energy Commission manages the discounts and can actually download the information from them in the individual applications for refund. It would theoretically be possible to mine the information by zip code, but perhaps because of information orderly. Now go through http://www.gosolarcalifornia.ca.gov/ discounts, I think, and perhaps they have information for you. Another way would be to contact the top 3.5 solar installers in the area, and ask how many have put in. Finally, if you have no choice, you can always go to Google Maps, satellite view and take a sample of how many houses have panels of (say) of one square kilometer, the scale for an approximation.
