Ever wonder how people feel about their solar energy, and their installer, a few years after having the system put in? Here’s what this customer wrote in a Facebook review on Nov. 8, 2017:

“I’ve had my system for over 2 years, have not paid 1 electric bill since and currently have a $600 credit with National Grid! Great group to work with, very professional.”

And on SolarReviews.com in March 2018:

“I love that they proactively check my annual production and will notify me of any issues. But I haven’t had any issues and it’s been almost 3 years now!”
