We reached out to New England Solar about a ground mount system after the constant electric rate hikes in the last two years. Andrew responded promptly to us and set up a site inspection. From there it was an easy process. Andrew went over some of the pro's and con's to adding batteries (we are set up to add them later) and what to realistically expect production wise. This included a detailed proposal we were able to look over and make sure we understood what we were getting into. Once we agreed, things moved pretty quickly and smoothly, with NES+ Green taking care of all town and electric company permitting. Something I think that also should be noted is that Andrew is detail oriented and on site. This is something I think is missing on a lot of the "fly by night" or larger businesses. Connection boxes and the like can only be so beautiful, a ground mount isn't winning a design award. That said, NES took the time to tuck our boxes away as much as possible and they also took care to try to minimize any extra bits on the mount themselves to keep them as clean looking as possible. Some people don't care how things look, but we do and it's something that should be taken into account. The installation was completed with minimal disturbance to ourselves and our property, and done quickly. 10/10 will use them in the future to expand our solar capacities as we go forward in the future.

Highly Professional and Competitive pricing

I am extremely happy with my installation of solar panels on my house (Western Mass.) We had a very large demand for our energy because of electric heating, and Andrew was able to design a system that accounted for over 80% of our demand and was still VERY reasonable in cost. I shopped around with both local and national solar installers, but NES+G had the best price per watt. Andrew was also very knowledgeable about every element of the process (including making sure our roof could properly support the system), and he made sure that he communicated every aspect and that we were comfortable with the design and cost. I did not feel ANY sales pressure like I did with other companies, and truly felt he designed and installed the system that we will benefit most from. I used Energy Sage to begin the quote and the process from there went very smoothly- the online quote was very close to the actual one after a site visit- AND the process allowed me to go from initial quote in late June to fully operation online solar in mid August! NES+G was extremely prompt with all forms of communication (usually a response within an hour or less!) and took care of every element of the project's paperwork and communication with the electric company. I am thrilled with the design (modern and sleek!) and with the experience of working with an incredibly professional and courteous team. I would highly recommend them for a residential solar system.

Best installers Upstate.

Buying Solar has become harder than buying cars these days but Andrew made the entire process painless. Everything from the initial site assessment to the final PTO required no effort or management on my side. Andrew was always a call or email away to answer the myriad of questions I had. You want actual roofers to do the install and that’s what these guys are. It was no surprise to me that they were the only Enphase Platinum rated dealers in the area. Also massive thanks to Andrew for dealing with permitting jungle that is Upstate New York.

Excellent Experience

Our panels were installed and working in September 2021. The work was fast, professional and had eye appeal. The problem we encountered was with Eversource! Regardless of the fact that we had paid our bill, in full, to NESG Andrew was active and persistent in getting our problems with the electric company resolved. His attention to detail and efforts have us up, running and yielding positive results. Instead of feeling like a customer, NESG made us feel like partners in this endeavor. I recommend NESG without hesitation. Scott

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!

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!
