How much electricity can you produce from the roof of your house? Roofray.com is a great site to figure this out and give you a rough estimate of how much solar potential your house has. What you do is put in your address, it brings up a satellite picture of your house, and from there you construct your imaginary solar array. After your array is build it gives you a performance analysis which tells you approximately how much electricity it will produce for you each month. It does this by using your regional characteristics such as average weather and cloud cover and orientation of your array. Lastly it figures how much money you’ll save each month with your array. To do this you put in your monthly electric bill or just an overall average if you like and it tells you how much you’ll save based on your power company’s rate.
I’m sure you’d be much better off with a professional assessment, but this is a fun first step to figuring out how you might benefit from having a solar array installed on your roof to supplement your power. Head over to roofray.com and have a go at it!
