Learning enough about solar and obtaining and comparing bids on all the critical factors is daunting. Solar sales reps want to be your sole source of all solar information and that is dangerous since they are not impartial, and in my experience, not even well informed sometimes. EnergySage facilitated me getting 7 bids in just a few days with only having to input some basic data and WITHOUT having to listen to 7 hour long sales pitches. I strongly endorse using EnergySage to help you get educated on solar and help you find and choose the best contractor and equipment for you. I liked being able to see all of the bids compared side-by-side on numerous basic criteria. Tons of additional impartial data and testing is linked to the bids. I selected my contractor with EnergySage and am happy I found their site.
