I was really keen on EnergySage at the beginning. Great concept. I wouldn't use EnergySage and would encourage others to not use EnergySage in the future. I'd find installers and then use a variety of other sites to research supposed top performers. I now am in a 25-year relationship with an installer who I'd argue is very different from the ratings on EnergySage I based my decision on. When you first go into EnergySage it's shocking how many nearly 5-star rated installers there are. Find that density of incredibly high-rated reviews ANYWHERE else on a review site. I found out there's a reason for that. Turns out when I did review my installer they called me up and were very persistent in getting me to remove my review. EnergySage doesn't have a problem with that. When I looked through the rest of the reviews, there is an incredible enthusiasm for solar installers which in itself raises an eyebrow. One review for my installer has "A+++++++++++++++++" in the title. It's like shouting off the rooftops about your plumber. So if you do use EnergySage (which again, I'd recommend strongly against relying on them as a singular source). Remember they have a very short relationship with you as a buyer and a long relationship with installers. Remember there is "survivor bias" in the reviews, especially in the highly rated companies so you should actively "deflate" the rating in your mind. Remember that there are plenty of other sites that provide solar insight and advice and you should actively use them.
