I was immediately connected to a human vs. an AI bot and have been guided through the process by the entire way. Randi had been my trusted guide and has been incredibly transparent the entire way. From the honest sales, pricing, and "human-centered" payment structure their approach to sales and support truly sets them apart. My install was smoother than I could've imagined and the install crew was informative, honest, and methodical in their set-up and clean-up. Deepest thanks to Cody, Jay, Mike, and Sean for getting us set up and running. Highly highly recommend and would work with them again.

E2 Solar made the process simple and their professional crew was outstanding. Something to think about if you live on Cape and want solar is our limited amount of sun. Even though Sun Power panels are a premium product and priced accordingly, they are the best at capturing diffuse light(when it's cloudy) and that was very important to us. Highly recommend E2 Solar!

We literally just turned our solar system on yesterday - so I don't have a history yet, but our…read moreexperience with E2 has been outstanding from beginning to this point. Their sales person was thorough, knowledgable and we never felt we were being pressured or rushed. They were willing (and not every provider is) to have their engineer come and go up on our roof (in addition to the satellite estimate for production) to inspect our shingles, etc. - they were 22 years old and needed to be replaced (which was not unexpected), but he also identified some other things to address. Other vendors wanted us to sign the contract before they'd do that! E2's in-office administrator has been relentlessly helpful, friendly, knowledgable and has made getting through the applications and approvals (from the State, power company, etc) a non-issue. She has taken a lot of time to explain things and help us navigate what can be very confusing details as you get going. E2's installation crew was, if anything, over-qualified. There were three certified master electricians on site (as required by law for the size of the job). Apparently, not every company fully complies with this requirement. Their installers made a point of working around our concerns for ground-level gardens and the house and the whole thing happened in a few days with virtually no disruption to us. I can't think of one area where E2 didn't excel. I can't speak to longer term service or quality, but we went with them because we believe that SunPower offers a better quality product and E2 is local and have been around. Plus, three of our friends/neighbors are working with them as well - so...safety in numbers? An unqualified rave so far. !!!!

Excellent Service, Reasonable Prices, Highly Recommended! I…read morehad a circuit breaker that kept tripping immediately, even after I replaced it. So I wanted a local electrician to come out to figure it out and fix. I wanted an actual local electrician not some company 2 hours away that pops up at the top of the list just because they want to start providing "service" in the area. (Found that out when trying to find a "local" deck builder a few years ago via Yelp). Anyhow, I called Ed, explained the problem, he had me check a few things, and pretty much identified the problem over the phone. He said he was on another job at the moment and would get back to me later in the day. Unlike many of the other services I've reached out to on Yelp lately, he actually followed through and came by late afternoon. Within about 10 to 15 minutes he found a short in an outlet and fixed the problem. I will not hesitate to contact Ed again for all my electrical needs! Now if I could only find a local plumber of the same ilk...

In April of 2013, Clean Energy Design placed 15 solar panels on our roof in Barnstable. Tom and his…read moreteam did a fabulous job, right from the start ... including accompanying us before the Old King's Highway Commission! That initial up-front investment was reduced over time by the absence of our former $1000/year electricity bills, by rebates and tax credits, and by Solar Renewable Energy Credits (SRECs) -- quarterly income from selling excess electricity. By the fall of 2018, we had broken even, and thereafter we became increasingly "money ahead!" Then in February of 2021, we replaced our Forester with an all-electric Chevy Bolt ... and lo and behold, we eventually started to get small ($90-$120) electric bills. Time to add ten more panels! So this year, Clean Energy Design once again delivered the goods professionally, promptly, and courteously. We could not have been more pleased with Tom and his entire team, from the office staff who handled all the permitting challenges to the hard-working gang who installed and wired in our newest set of panels. We would recommend Clean Energy Design to anyone!

At the time, Matt Ciocchi assured me that he was going to make sure we were very happy with our system as long as we owned it. In the first six months we had a couple issues and Matt dealt with them pretty well. In late August of 24 the system went down. Matt diagnosed it over the phone and that was the last I heard of him. He did not take my calls or respond to emails. I ended up having to contract another company to fix, at a premium that Matt assured me I would never have to pay. The system was down over a month. I only hope through writing this review that I spare someone the expense and headaches of working with Matt Ciocchi and DIY Solar.

Look no further if you need electric work done. I am debating about having him do electric work so I can have a portable generator available to use. He really is knowledgeable and honest.
