Battery Storage Solutions for Homes & Businesses

Great experience with Valley Solar! The process was easy and straightforward, and Martin was awesome to work with—super knowledgeable, friendly, and never pushy. He answered all our questions and made everything simple to understand. Highly recommend Valley Solar, especially if you get to work with Martin!

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!

Wonderful experience all the way around with Valley Solar. They were professional, informative and responsive throughout. They sent progess emails bullet pointing next steps, kept us apprised as each step was completed and responded to any and all questions promptly. There was confusion regarding the timeline early on which was quickly settled in our favor. We enthusiastically recommend Valley Solar.

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.
