NuWatt Energy

Established: 2010

EnergySage Rating Value: 4.5 from 52 reviews


The last review from EnergySage:

I went with Nuwatt because I was very comfortable with their sales rep Maan. He was very thorough and patient in our decision making since this is a big investment. The project caught a few snags from Eversource but Nuwatt team was very responsive in getting the job done. The 8.16 kW PV system looks great on my roof and I am recommending Nuwatt to my neighbors and friends!

Energy Monster

Established: 2010

EnergySage Rating Value: 5.0 from 20 reviews


The last review from EnergySage:

The guys at Energy Monster did a great job. They were polite, professional, and answered all my questions and concerns. They took care of a needed carpentry job in the attic, a knee wall, at no extra charge, as well as the building permits, and provided the documents needed to get the state and federal tax breaks. The whole process took longer than I expected, but a big part was waiting for Eversource to connect my system to the grid. But all in all, it was a great experience.

DeFreitas Enterprises, LLC

Established: 2015

EnergySage Rating Value: 5.0 from 6 reviews


The last review from EnergySage:

I really enjoyed working with Alex DeFreitas. He was very knowledgeable, forthright, and seemed sincere. The system he proposed was enough to eliminate my electric bill and then some and was designed with top of the line panels. I only decided to go with another provider as I found an outfit that was local and designed a system that almost doubled my needs as I plan to add high power needs equipment to my farm.

RevoluSun

EnergySage Rating Value: 5.0 from 20 reviews


The last review from EnergySage:

I made my decision to use RevoluSun in part because of Richie Bonney, the sales rep. He’s incredibly knowledgeable and really good at answering questions/explaining things and made the other reps look like chumps in comparison (I say this tongue-in-cheek but it’ true, frankly).

The last review from EnergySage:

I met John Boiano about 5 years ago and I knew he had worked in the solar industry. Over the last few years we would talk a little about what he was up to and eventually I decided to actually find out if a PV solar system would work for my house in Eastern CT. Without any pressure, John outlined what would be involved and came out to do some measuring and calculating as to what might work.

Harvest Sun Solar

Established: 2014

EnergySage Rating Value: 5.0 from 3 reviews


The last review from EnergySage:

I was looking for a local installer for my solar project. Selecting Harvest Sun was easy after contacted four references. Harvest Sun is “what you see is what you get”. The only price change from the original proposal was the addition of EV charger feature to the inverter. My project took six months because the location of my house required multiple hearings from local boards. Sean helped us throughout the hearing process until we obtained the permit. He is also responsive in adjusting his work crew schedule so we can complete the project in 2019. Harvest Sun did all the necessary “paper” works for us, for net metering and for the MA renewable energy incentive program, SMART. I am now enjoying 0 monthly bills with credits even with the charging my EV and electric lawn mower
