Going “green” can be a pain in the neck. It can get really confusing trying to sort out all the options. It's enough to make you want to forget it all, crank the AC and mix recyclables.

That's why it's refreshing to find a tool like RoofRay. It's a website that helps you calculate the value of putting solar panels on your roof. Using Google Maps, you zoom in on your house, then use RoofRay to draw in solar panels. The site will then figure out how much energy you should expect to generate, as well as the cost to install a solar setup.
