RoofRay Determines the Solar Potential of Your Roof

This is quite interesting:

"If high energy prices have convinced you that solar energy might be the ticket to cheaper bills, head to web site RoofRay to determine the solar potential of your roof.

As you can see from the video demo, the web site lets you draw the area you're interested in adding solar panels to on a Google Maps mashup, determining everything from surface area to slope.

RoofRay will then estimate the power potential of your roof. It may not be the most accurate estimate you can get, but if you're considering harnessing the power of the sun, it seems like a good starting point."

Looking forward to see a program that can use Google maps to auto detects roofs(+angles) and link that to Weather sites with seasonal light hours and starts to calculate community potentials. Same thing would be possible for other natural energy sources. Interesting spot market.
