The State of Solar Power in Cambridge

Based on a careful analysis of publicly available solar installation data, our work shows that Cambridge has installed over (NEW AS OF YEAR END 2014: 2.8 megawatts (MW)!) of solar in the last 10 years, the vast majority of that being installed in the last 2 years!  Based on the Mapdwell solar map for Cambridge, we calculate a total rooftop solar capacity for Cambridge of at least 400 Mw.  So there is room for many more solar installations in Cambridge, saving money, reducing pollution and preventing climate disaster. Contact us if you would like to find out more.
