The city of San Francisco has launched a Google Maps mashup today that plots the locations of solar installations and activity throughout the city. Map markers indicate if the solar installation is residential, commercial or municipal and unique installations are called out with an expanded case study for you to read more about. The map also allows you to enter your specific address to learn more about what solar power can do for you as a home or business owner based on the size of your roof and other factors.
Try out "11 Grove Street" for an example:
Roof Size: 5936 sq. ft.
Estimated solar PV potential: 7 - 15 kW
Estimated electricity produced: 12775 - 27375 KWh/yr
Estimated electricity savings: $1460-$3129 per year
Estimated carbon savings: 9530.15 - 20421.75 lbs per year
This fantastic maps mashup is a joint initiative between SFEnvironment and CH2MHill..

Thanks for the positive comments about our site. This has been an exciting venture with the city/county of sf.

Check this Map out, has United States Interactive Carbon Footprint Map, illustrating Greenest States. This site has all sorts of stats on individual State energy consumptions, demographics and State energy offices.

The map has interesting features, but the data for electricity produced is at least 50% too high. The calculations on the map (as of 11/07) are based on an output of 5 kWh/day per kW system. Actually, as shown by the 11 SFPUC solar monitoring sites, average insolation in San Francisco is about 4.5 kWh/day per meter squared. As demonstrated by the Moscone Center and other sites, the AC output is about 2/3 of the insolation, i.e., 3 kWh/day per kW system. More detail is given at www.sfog.us/solar/sfsolar.htm and www.sfog.us/solar/moscone.htm
similar idea at http://neighborlysolar.com/installations.php with fewer bells and whistles
