    "Great service, communication, and professionalism from start to finish"

    We recently had our system installed and up and running. Working with NESGS was a great experience. Right from the start Andrew kept up great communication. He was very prompt and thorough with his answers to all the questions we had. He went above and beyond to help us get the financing and incentives available to us here in NY. He also worked out the best equipment to cost ratio to optimize our incentive situation with our finances. He was very willing to find us a solution in a complicated situation and worked diligently through all the red tape and confusing answers from the various NY state solar programs. He and his crew worked quickly once we had the green light for installation, we were surprised how quick it actually was. The panels look great in place and we've been having a great time watching our solar gain each day. We have yet to see an electric bill reflecting our gain to usage ratio, but everything about our experience so far suggests Andrew created the best system to fit our needs. I would highly recommend NESGS to anyone looking to put in a solar system. They have the touch of a small company, but the security of a long time in business and really take their time to meet the needs of their customers.

  • "Great Installer and Local!"

    Reviewed Apr 24, 2020

    Local! I try to support local businesses the best that I can. After multiple quotes the decision was easy, New England Solar + Green. Their team was professional, quick to respond and answered all my questions. We were left with a great looking install and the process took just under a month from start to finish. Love our 9kW array!

    I met Andrew, owner/founder of NES&G under less than desirable circumstances: my grid tied system was ailing and my original installer was being less than helpful.
    Andrew got right to the issue and solved my problems all the while sharing information with me that I wish I had when I originally was looking for a Solar energy contractor.
    The body of knowledge needed to be a truly competent installer is huge and complex. As consumers we are told to ask a lot of questions and get multiple quotes but paramount is that you have to trust your installer to do right by you.
    NES&G should be on your list if you are considering a solar (PV) project; if you need repairs, this is the guy to call.
    Highly recommended!!!
