    • The biggest complaint we hear from homeowners who are considering rooftop solar systems is the lack of information: How much will it cost; how long until it pays off; who’s the best local installer? A new site that launched this morning, is looking to help answer all of those queries using satellite data and a hands-on web site — RoofRay.com.
    • 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 (see image below and YouTube video below the jump). 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.
