Valley Solar .

We have had Valley Solar panels on our garage for several years and have loved the savings. We recently noticed that one of the panels was not working. I called the office and left a message. 5 minutes later I was called back. The very next day they sent a tech out to fix the small electrical issue with a connector and it was fixed! What amazing service. Everyone who works for them are polite and professional. I highly recommend them!

We bought a house in Williamsburg in July 2025 and immediately started looking for solar providers to beat the end of the year deadline for tax incentives. We called a competitor of Valley Solar that many of our friends and family had used and they told us they were too busy to get the job done by the end of the year, but actually referred us to Valley Solar. Valley Solar totally came through and beat the end of the year deadline by almost a couple months! I will say that our installation may not have been as challenging as other sites (new roof, large area with no obstructions, easy access, etc.), so that could’ve factored in but, regardless, the team there is fantastic. From the original assessment, to the proposal, and then onto the installation, everything went super smoothly. Also all the guys on the crew are just awesome; really nice and fun to chat with about the technology. Our house is at the end of a long road with many tall trees hovering over the power lines, so we definitely wanted a battery backup to go in with the new system for peace of mind. However, we did not want a Tesla battery and Valley came through here, again, by offering an alternative battery competitor’s product (Franklin), so we were thrilled that we could buy that instead. The app that comes with the Franklin battery is also amazing. Not only does it track everything coming out of the panels and into the battery, but it also tracks everything going out to the grid and even lets you time your energy export to the grid to match the maximum payback for the electricity from the utility provider. The battery app also gets alerts from the national weather service and automatically puts the battery into emergency backup mode if it sees an upcoming weather event. We had an outage 2 days after the installation was complete and it flipped over to battery power so fast we didn’t even lose our wifi in the house! I’m just blown away by the whole technology. The installation in the basement of the house is also immaculate and impressive. We could not be happier with the service we received from Valley Solar and also the follow up on getting the rebates and enrolled in all of the energy saving programs. It was so smooth. We highly recommend.

After doing research, Valley Solar clearly stood out as the best company around. We spoke with our local inspector, who specifically recommended Valley Solar, which gave us a lot of confidence in moving forward. This has been echoed by other local contractors we’ve worked with since! From the beginning, the team was knowledgeable, transparent, and never pushy. They took the time to walk us through the design process, answer all our questions and made sure we fully understood our solar/battery system as well as the overall process. One thing that really set Valley Solar apart is their Sun-Alert system. We liked that Sun-Alert actively monitors the system and flags issues before you even notice a problem, which provides real peace of mind and clearly adds long-term value. Unlike other companies we spoke with that rely on third-party monitoring or warranty providers, Valley Solar handles everything themselves. We also felt good that they have dedicated service teams, which shows the emphasis they put on the service side of things, not just the front end sale. The installation itself was fantastic — professional, efficient, and incredibly well-organized. The electricians Jason and Andrew went the extra mile to avoid exterior conduit on the main roof which we certainly appreciated! The crew showed up on time each day and treated our home with care and respect. Communication throughout the project from Dawson, Kate and the other office folk was excellent, and everything was delivered exactly as promised which can be rare these days! Valley Solar delivers more overall value than any company we looked at, combining technical expertise, outstanding customer service, and true ownership of their work. On top of that, they are a local outfit so our dollars stayed here in Western Mass. We couldn’t be happier with our decision and would recommend them without hesitation to anyone considering solar or batteries!

My family offers Valley Solar an unreserved recommendation for any solar/battery storage system that you might want for your home or business. They will do quick, excellent, and reliable work that will exceed your expectations, and someone is always available for any questions you might have before, during, and after your installation. Google says I need to omit the quoting/initial part of the permitting process due to review length... Sam was a great expert that was thorough and patient as I learned about solar power. Slightly more than a month after calling Sam during an "Easy Quote" (impressive with how many other people were doing the same thing I did), I reviewed and signed a full proposed construction agreement. However, Eversource delayed my project for a technical review of their own, and they demanded that I pay over $11,000 for a grid infrastructure upgrade that “would be needed to prevent overloading of secondary transformers.” Instead of hiding this or asking for more fees of their own, they immediately had me work with the vice president of sales. I was honestly ready to cancel the project until I talked to Mike; he knew there was a way to negotiate with the utility to make the project happen. Sure enough, less than 3 weeks later, they re-submitted the application for my system with an “export limit,” and Eversource approved the installation to proceed sans grid upgrade. Now, at this point, Mike was sounding a little nervous; I was tentatively scheduled for early January with a “high likelihood of moving up.” Little did I expect Dawson to call me in the middle of November, asking if this team could have a head start on November 19th. Of course I accepted, and the men who arrived at my home on that day did amazing things in less than 7 hours. I do need to point out the dedication of this team; a solar installation with battery backup can take up to a week of electrical and structural work. The racking, hidden conduit, and swap-out of my entire electrical panel was done on that day, and I need to thank Andrew for refusing to leave the job site until he knew the power was back on after his full panel swap. The team returned in early December (just like they said they would) and installed/wired the battery, every panel, disconnect, conduit, and wire (there was a lot of wiring) in just two days. The team was hard-working and meticulous; they even moved the 300 pound Powerwall from one mounting location to another over uneven and half-frozen ground, just because they were worried the fire department might not like it! Andrew even pointed out how much better the new location would allow him to hide conduit. Look at the pictures; everything looks great with ZERO exposed wires or conduit outside of my home. It’s a joke in construction that electricians are the messiest trade, but Valley Solar’s electricians respected my home and cleaned up every wire and sheath that they could. On December 11th, with hands freezing in the cold wind, Andrew and his team flipped the breaker going to my Powerwall, closed everything up, and then we watched the Tesla app report the first solar AC production occurring at my home. In conclusion, Valley made the best system; it exceeds my expectations and reasonable production estimates from PVWatts and Gemini AI alike. They installed it quickly and at the best time, at the best price. They used highly efficient bi-facial panels, which are more expensive than what national competitors might use, but allow me to have much more production, including on cloudy days. They used construction practices and design practices (including certifications from outside contractors) that make me believe this system might actually last 25 or more years, like they warranted. I am glad I called Valley Solar. I’m very pleased with their work. I would hire them again for any major electrical projects, and I trust that they will stand behind their work for a long time to come. If you call Valley Solar for your project, I hope that you find them as ambitious, excellent, dedicated and reasonable as I did.

We had several companies approach us over the past few years, offering solar installation. As we researched and considered the process, we learned that many of our neighbors enlisted Valley Solar for their homes, and they were pleased with the work. The staff at Valley Solar were patient and professional. They listened to concerns, and took time to thoughtfully answer all our questions. When unusual circumstances arose during the project, the manager Patrick extended himself more than once to assist and support us through the project to the very end. He and Valley Solar provided exceptional work and customer service. I highly recommend them to anyone considering installing solar.
