The new software program has determined that 80% of all US rooftops are “technically viable ” for rooftop solar. Some locations are more “viable” than others, of course. Houston, Texas is judged to be the best American city for rooftop solar power. Project Sunroof says that city could generate up to 18,940 gigawatt-hours of solar electricity each year. One gigawatt-hour is enough to power 90 ordinary homes.
Project Sunroof lets you search for your house, suggests how large a solar array you might consider putting on your roof, and estimates how much energy it will generate. It also estimates how much it would cost you to lease or buy the panels. Source: Solarlove, full article HERE.
