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.

I’ve had my solar panels for over two years now and have been very happy with them. Dealing with SunBug has been a pleasure. I’ve been impressed with their professionalism. So far I haven’t had any problems with my panels. I would recommend them.

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

Cotuit Solar LLC

Established: 1988

EnergySage Rating Value: 5.0 from 5 reviews


The last review from EnergySage:

We had a great experience with Cotuit Solar. It started with the sales and went through to live date and beyond. The sales person was the most knowledgeable sales person we met out of all of the companies we talked to – which gave us confidence in the company. The install crew was AWESOME!! They were respectful and kept a clean job site. After going live we had a couple of questions and the office crew was super responsive- even after we had paid. This is a company from beginning to end that is committed to helping people go solar.

Whaling City Solar

Established: 2020

EnergySage Rating Value: 5.0 from 3 reviews


The last review from EnergySage:

Being in downtown historic New Bedford means we needed to navigate not only the city’s standard approval processes, but also the ones in place to maintain the historical authenticity of the National Historic Urban Pack area. Helping us through this entire complicated process is where Whaling City Solar really shined. Yes, their Solar systems are top notched. Their monitoring systems tell us the exact amount of energy produced, and we can see ongoing savings in real time. But the real value was how easy Whaling City Solar made the planning, approval, and installation which all occurred through the tough COVID times. Appropriately, we ‘flipped the switch’ during a joint event with Whaling City Solar and town officials on Earth Day 2021. Everyone in attendance was enormously happy with the outcome.
