NuWatt's recent customers describe a company that moves quickly. A March 2026 reviewer's 9.6 kW system went in before the end of the year as promised, and a failed microinverter was fixed that January. A February 2026 customer went from planning to active production in a couple of months. Another in March 2026 found NuWatt through EnergySage, had the rooftop panels designed and installed, and says the support has kept coming since. The company sells and installs solar, Tesla Powerwall storage, heat pumps, SPAN smart panels and EV chargers out of Woburn, for homes and for commercial, nonprofit and municipal buildings, and lists a nine-state service area reaching from Massachusetts to Texas. It says it has 15 years behind it and 2,500 homes electrified, and describes itself as a Tesla Powerwall, SPAN and Enphase Gold certified partner. Its Massachusetts home improvement contractor registration, number 167805, is active on the state registry; its Massachusetts electrician licence, number 794, is expired there. Where the work goes well, customers are specific. Panasonic panels with 25-year parts and labour cover. An electrician who worked through the winter to finish an install. A system whose output matched the projection exactly. A homeowner three years in whose Eversource bill now averages $12.91. Warranty parts replaced years after the sale, and a gateway failure in 2025 escalated to a call the company set up with the manufacturer. Shehzad, Maan and Madhukar get named for answering questions within hours. The complaints are older, and they are about what happens after the contract is signed. A December 2023 customer says a heat pump job sold as a single weekend turned into two weeks of no-shows, with the old heat source disconnected and a floor left unheated. An October 2023 customer in New Hampshire says his project was still not complete more than a year after signing. A January 2023 reviewer says he was ghosted once he said he was ready to order. A January 2024 reviewer wrote that he intended to file complaints with the Better Business Bureau and the Massachusetts Attorney General's Office. A February 2025 customer cut a five-star review to three after calling four times with the same question about his system and hearing nothing back. Google shows 4.2 stars across 53 ratings, against the 4.9 from more than 500 reviews the company advertises on its own site. For solar on a Massachusetts roof with Panasonic hardware and a long warranty, the 2025 and 2026 accounts are consistently good, including on warranty work years later. Before you sign, put the schedule and the after-installation support into the contract — who answers, how fast, and what happens if the install slips — and ask directly about the expired electrician licence and who will pull the electrical permit for your job.

I found NuWatt through Energy Sage after getting several home evaluations and estimates for solar panels. I was very happy with NuWatt's service in planning and installing the rooftop panels, and with the ongoing support since then. The panels have functioned very well. Included software allows me to monitor my solar electricity generation day-by-day or over longer periods of time. My electricity bills are lower than previously. As electric bills increase, the value of my solar panels has become even greater. I installed the solar panels to lower my family carbon footprint and to make our regional electricity grid more resilient to periods of high demand -- both ways to help with the important transition to renewable energy. And, when I sell my home, the warranty will be transferable to the new owner.
Thank you NuWatt for delivering on your commitment to install my 9.6 kw system before the end of the year. I am delighted with the urgency provided and the quick response to fix a microinverter in late January.
I reached out to NuWatt in 2025 and they were able to finish my project from planning to installation to active production all within a couple of months. Their service was responsive and I am loving having Solar installed on my roof. Huge Shoutout to Madhukar and Shehzad for following up on the progress, answering all my questions and responding in a timely manner. Totally recommend NuWatt Energy for your solar needs
Going solar was a big decision for me as a homeowner, and after doing a lot of research and talking to multiple companies, I’m so glad I chose NuWatt Energy for the job. From start to finish, the entire experience was smooth, professional, and exceeded my expectations. The team at NuWatt Energy was knowledgeable, punctual, and respectful throughout the process. Communication was excellent — they walked me through every step, handled all the permits seamlessly, and kept me in the loop at every stage of the project. The installation was done efficiently and with great attention to detail. The crew made sure everything was not just functional, but also aesthetically clean and safe. Special thanks to Shehzad and Azmi, who were my project managers. They were both incredibly responsive and patient in answering all my questions, no matter how small. Their prompt support made the entire process stress-free. I also want to give a big shout-out to Mann, the Director of NuWatt Energy, who took the time to explain the system design, solar market dynamics, and how NuWatt’s offering stands apart. His clarity and deep knowledge of the product and the solar industry were extremely reassuring and helped me make an informed decision. Post-installation, their customer service has continued to be top-notch. The system is up and running smoothly, and I’m already seeing positive results. I highly recommend NuWatt Energy to anyone considering solar. They deliver on their promise, and more importantly, they care. A truly 5-star experience.
Overall a good experience from initial conversation with Maan till regular followups with Shehzad. I believe it’s good value for money investment with NuWatt as the Panasonic panels seems well built and have a good reputation. Shehzad was real quick in replying and answering questions. My system is yet to start producing energy and connected to grid however process so far smooth.
