Determine Your Rooftop Solar Power Potential.

You are living in an independent house and are forever looking for some guide tips to install solar PV system. Before hiring a consultant to design a solar PV system, you are keen to know the potential of your rooftop. How much of power it can generate. A rough approximation or better thumb rule suggests that one can generate 8-10 W per sq. feet of solar panel area. Roofray is a wonderful utility which lets you explore the solar power generation potential of your roof top.

This app is based on Google Maps. The steps are very simple. You need to first enter your address in the input box and by pressing “GO” you get a Google Map preview of your address.

Second step is to mark four corners your roof on this Google Map app. You would be optionally required to select whether the roof is flat or has slope.

After completing above steps you would be taken to next page where you may have to specify your average power consumption.

The details so obtained may not be very accurate and for working out the cost benefit analysis you may have to take the help of some of the experts in this field. But for preliminary analysis, the site is really cool.

The app works quite well for US locations but for rest of the world the details on area of roof and solar power generation potential so obtained are quite handy.
