Energy Sage is the Consumer Reports of the Solar market. I wouldn't make any large purchase that is reviewed by consumer reports without first consulting them and I would urge anybody interested in Solar to not make any decisions about solar without going through Energy Sage. They are an invaluable, unbiased source of information on solar in general. More importantly they do a great job getting you very detailed quotes from vetted, reputable companies. Being a large, once in a lifetime purchase (hopefully), energysage is argueably the most vital part of your Solar buying process. I could not be happier with how our solar buying process went and that is because I used Energy Sage.
