The cost of photovoltaic solar has dropped by over 80% since 2008.
Is solar now cost effective for you?
Google’s Project Sunroof can help you decide. Project Sunroof has built 3-D models of rooftops in all 50 states, looked at the trees around people’s homes, considered local weather, and figured out how much energy each house or building can generate if its owners buy solar panels.
Google has found that nearly 80% of all buildings it has modeled are viable for solar panels.
