I went with RevoluSun primarily due to their consistently high ratings on review sites and the BBB…read more They were not the lowest price. However, the lowest price vendor had aweful ratings and very poor BBB reviews. I'm happy with RevoluSun's price. I had a Zoom sales meeting in late February and the panel was turned on in July. A large reason for the five-month delay was town and power company inspections. I was told these delays are expected ahead of time, so no surprise. The steps involved included getting aerial surveillance, plans for the job, checking roof stability, electricians, and as mentioned before inspections, inspections, inspections, and more inspections. The actual installation was done in two mornings, clean and without any issues. I only have the highest regard for the RevoluSun people involved. Pros: Work was done without any problems. My first electrical bill was $5, the next two were around $20. Not $250. I believe them when they said the panels should be paid off in 6 years. I believe my total cost (after tax rebates) will be about $10,000. Cons: I reviewed the contract very carefully and found a number of flaws (e.g., missing guarantee for the panels' life, some damage exclusions made no sense). I'm no lawyer, but it pays to read the 'fine' print. They approved my revisions. The final visit and review of the app was originally scheduled as a Zoom meeting. There were enough details (e.g., what the 3 indoor and 2 outdoor switches do - and what I need to do in an emergency, the app showing electrical savings, review of the power company's 3 most recent bills) that I strongly suggest it be a person-to-person meeting. The project manager sent four emails trying to get it to be a Zoom meeting. I was able to get a vice president to explain the system. A very, very good 1-to-1 meeting.

If you're looking at a solar install, look no further! Paolo Ricci, Project Developer was my go-to…read moreguy and he was great from beginning to end. From the start he came with detailed information, a very well thought out proposal and clear pricing. All that, and he didn't have the typically pushy approach. I think they know that the work they put into the proposal does the heavy lifting. If you're looking for pros to take care of your advanced installation, this is the team. I had them install a SPAN smart panel and two SolarEdge batteries in my system and everything runs great! The team was responsive and communicative throughout the entire process, and always quick to chase down any answers to my very specific questions. They handled all the incentive and connected solutions paperwork and I'm confident they'll continue to support their product into the future. 10/10 would recommend.

I talked to absolutely every one about a solar panel installation. I easily spent months on…read moreresearching the topic, vendors, and installation techniques. Ultimately I settled on on a mechanically mounted system for my flat roof, which was wonderful. Some vendors would not touch a flat roof. Some only installed ballasted systems. Some vendors assumed that they could use a lift to get onto my roof when they actually needed a crane. Some just wanted to overcharge me with the hot new technology, sweeping the nation. After reviewing multiple bids, I settled on Sunbug to install my system. Chris Miller was a no nonsense saleman throughout my whole research phase. He answered all of my questions, and disabused me of any misinformation I may have had. He was polite, but firm, which is exactly what a layman consumer needs when making a large, delayed gratification purchase like a solar system. Once I signed on the dotted line, their team actually moved fairly quickly through the rest of the process. We were able to install my system before the end of the tax year, so some of that delayed gratification is delayed just a little less. I would give a five star review, but there were a few hiccups. Once I signed the dotted line, the team was less responsive than I needed with my subsequent questions. They installed the inverter in my basement without my input, which is a problem when I plan to finish my basement. We quickly fixed that by simply moving it, but we could have avoided that problem altogether by filling me in on the plan first. I chalk that up to some disorganization, and rushing to complete systems before the end of the tax year. Another silly issue is that their electrician upgraded me to a 200A panel, which is wonderful. For some reason though he reinstalled the same 100A main breaker I originally had, which makes no sense. Now I have to pay some one else to upgrade my main breaker. A month later I am actually still waiting for an inspector to check off on their work so that I can turn the system on, but that may be more an issue with the inspector than with Sunbug. In any event, I am mostly pleased with my purchase, and look forward to bathing my roof in sun shine in the coming years.

After months of not receiving any payment for my work, I asked them for payment and why I haven't been paid. They told me they would pay me but never did, and from then on it has been nothing but lies, excuses and avoiding my calls. It is hard to believe a company would treat their employees so poorly but Commonwealth Energy has no problem doing that to people who work for them, so I doubt they care about their customers either.

I do not recommend working with this company. I started the home energy assessment process 13…read moremonths ago to get insulation done at my home and had multiple issues in this unnecessarily long process. Communication is horrible - it took a very long time to even get a scheduled date. Then after an audit by Mass Save, it was determined that there were missing spots in the walls from their work so Commonwealth Energy would need to come back and fix it - but they are not answering my calls or emails to complete this work. They did answer my call once really quickly when I was transferred by Mass Save (so it showed a different caller ID), but then again not contactable after that, so I am assuming they are not picking up my calls personally. And I can't easily change contractors because Commonwealth Energy would need to be the one who submits the "change of provider" form to Mass Save. Even if I need to be scheduled far out on the calendar, I just need to know instead of being ghosted.
