Thinking About Solar Panels? See How Much Sun Your Roof Gets With This Map

You need a sunny roof to benefit from solar panels, but yours may be sunnier than you think. Google’s Project Sunroof gives building-by-building details, and now has data for 50 states in US.

Search for your house, and take a look: sunny spots are in yellow, shady ones in purple. Google also provides estimates of how many hours of sunlight your roof sees, how much area is available for solar panels, and how much a solar panel installation could save you over the years. It also has details on financing and more. That makes it a great place to start thinking about whether it makes sense to install solar panels.
