Posted on petenardacciTrustindex verifies that the original source of the review is Google. Trinity was pushing sales in the neighborhood, and we were given time and several estimates by their sales rep on several choices- to add on to our existing solar system. I would prefer a more local business- and even if the installation cost would be less from Trinity, my mindset is to stay local- Why? -New England Solar +Green answered the phone with a real person, and I expect that if any problems arise, a local company should be able to address issues much faster- they are HERE! A big box company like Trinity will send a sales person who collects the sales commission, and is never seen again. Andrew at NES+G stopped by, and was super educated and informed about all things solar- our questions were answered immediately, and without hesitation. Andrew's knowledge and experience showed right from the start, which made us feel quite comfortable! After several estimates were presented to us, we chose NES+G! Throughout installation, Andrew was present- start to finish! I mentioned this fact to Andrew who responded that "These jobs need to be done MY way!" - which strikes a particular chord with ME- This is MY house, and I want things to be done MY way! Our confidence in NES+G just grew tenfold! Issues with our older solar system were addressed by NES+G promptly, and the new system was tied into an app that allows us to see what both systems here are doing in real time. Andrew, his company, his crew, his electrician- were friendly and super confident- did amazingly neat and clean work, and I challenge ANY company to do better than NES+G!! I have to say that this contractor experience was the most painless procedure this household has ever seen-we are so impressed, our expectations so greatly surpassed that we are at a loss for words! Andrew and company, thank you so much for being there and walking us through the entire process, clearly the correct choice is NES+G!!Posted on Rob SekowskiTrustindex verifies that the original source of the review is Google. I had a great experience using New England Solar and Green for our solar project. Andrew answered all of my questions thoroughly, came up with a design to maximize our production, and a fair price to install. Andrew was always on site and his team was always on time. The level of service and time to install beat all my expectations.Posted on M. Jennifer BloxamTrustindex verifies that the original source of the review is Google. I researched and met with the competition, and New England Solar was by far the best choice. Andrew Guntlow is a complete professional in every way - incredibly knowledgeable, thorough, and responsive. He's on site every step of the way - on the roof, in the house, making sure everything is done right. An A++ experience!Posted on RussTrustindex verifies that the original source of the review is Google. Andrew and his team were very dependable, knowledgeable, professional and it was a pleasure doing business with them. Andrew sent us a very detailed proposal, kept us informed about the project, answered all of our questions, handled all the paperwork. We would highly recommend NES+G for your solar project.Posted on Jill RehmannTrustindex verifies that the original source of the review is Google. we had planned to put solar panels on our house when we built it in 2018 but delayed the decision for a couple of years due to finances. We struggled to find a solar panel and installer and happen upon New England solar and it’s primary person Andrew Culo as soon as we met with Andrew on the initial interview we knew we’d found a reliable, enthusiastic and knowledgeable, solar man and we weren’t wrong. He and his partner installed our panels with very little delay, he consulted with us on a regular basis for what we needed. His company walked us through all the regulations and other hook up issues that we might encounter and did all the basic paperwork so that there was virtually nothing that we had to do once the panels were installed. We found our experience with Andrew exceptional and have since recommended him to our good friends who are also now building a house. We recommend him to anyone who reads this.Posted on Ursula BareTrustindex verifies that the original source of the review is Google. My experience with NE Solar + Green was excellent. Andrew came by to evaluate the property and provided me with a wealth of information. After receiving the proposal, he answered all of my questions promptly and with great detail. He took care of all the paperwork for permits and for the interconnection. The install went quickly and they did a great job of cleaning up after each visit. The communication was excellent and made every step easy. I highly recommend them for solar installation!Posted on Robert LeBlancTrustindex verifies that the original source of the review is Google. Andrew was the consument professional. He and his helper, installed our solar array flawlessly.Posted on Katherine NahumTrustindex verifies that the original source of the review is Google. My son and I collaborated on this solar project. We give Andrew 5 stars because he entertained and answered all our questions, and delivered spectacularly on the timeline. He is a little stiff inter-personally, but that is probably because he is so bright.Posted on Peter FilkinsTrustindex verifies that the original source of the review is Google. Andrew was very responsive and able to inform us about all aspects of installation and performance. The installation was swift and very professional. Highly recommended.Posted on Roxana GironTrustindex verifies that the original source of the review is Google. A special thank you for isabela on guiding me through the process
