RoofRay.com – Calculate Solar Potential
We’ve been wondering if installing solar panels on our house would be worth it. But, most of us still still hesitate because we have unvalid information: How much will it cost; how long until it pays off; who’s the best local installer? Roofray.com is a great site to figure this out and give you a rough estimate of how much solar potential your house has. Here’s how it works: enter an address, pull up the satellite image of the chosen building’s rooftop and then using the RoofRay tool based on Google maps, draw your solar arrays. Data on square footage of the system, slope of the roof, power per square foot and total peak power all show up in a chart, and the info displayed depends on how big you’ve drawn your system. Although the site is geared toward California users, It is still able to figure that it would take $50K to install enough solar panels for people to go off the grid in Wisconsin. Sounds expensive, but that’s not so bad considering our system would pay for itself in 13 years, help save our beloved green earth, and reduce our dependence on oil and energy weasels, both foreign and domestic. So should I go solar? Maybe we’ll wait — in five years it’ll cost half as much and deliver twice the wattage.
