Clean tech company Mapdwell has identified 3 GW worth of potential rooftop solar PV in its newest location of San Francisco.

Less than a week after the MIT spin-off company revealed that New York rooftops had the potential for 11 GW worth of rooftop solar, the Boston-based urban solar mapping company has revealed that California’s San Francisco has a potential 3 GW of potential rooftop solar PV capacity at its disposal.

“San Francisco’s 160,000 roofs can power 380,000 American homes with energy from the sun, making San Francisco our brightest project so far,” said Eduardo Berlin, CEO at Mapdwell. “This is an $11 billion opportunity for California’s clean energy industry, which could offset carbon emissions equivalent to planting 65 million trees. Mapdwell is here to help California work with the sun.”


Last week Mapdwell opened up its software to New Yorkers, whose more than 1 million buildings have the capacity for up to 11 GW worth of solar PV capacity. Mapdwell launched Solar System New York City on August 21, and have now followed that up with Solar System San Francisco.

These online tools allow homeowners to gauge the potential solar energy they could be creating with solar rooftop installations on their own houses — all without the need to ever leave the comfort of your lounge room. This makes it a lot cheaper and efficient than attempting to measure your own roof and estimating costs, or even hiring a professional. Mapdwell has become the professional for you, and opened up its information for anyone to see.

Solar System is now available in Boston, New York City, Washington DC, Boulder, Washington County in Oregon, Wellfleet, as well as in some international locations.

And Mapdwell’s two announcements come hot on the heels of Google’s own new solar mapping initiative, Project Rooftop, which has been rolled out in the San Francisco Bay area, Fresno, and Boston.
