Ecoloop Solar Solutions installs rooftop solar out of Danvers, backed by a genuinely large sales and project team — reviewers name more than a dozen different reps, from Tim Matuszewski to Joy Goncalves to Fabiana Zarbano, each credited with walking a homeowner through design, permitting, and installation. Its Massachusetts electrician license is active, and it holds an A+ rating as a BBB-accredited member. The thread that runs through most of the reviews is what happens to the electric bill afterward — several customers report going from a normal monthly bill to $0. A number also describe getting a full roof replacement bundled into the project at no extra cost when the existing roof needed it before panels could go up, and a few mention an EV charger added as part of the install. On Google the company holds 4.9 stars from 131 ratings, and Angi shows 5.0 from a small base of 3. Two recent reviews are worth weighing against that. One customer says the sales process was strong but that once the contract was signed, the assigned team couldn't answer technical questions and didn't manage the project well. Another describes a leak that developed after installation, with the company attributing it to a roof it says was already faulty — a claim the homeowner disputes, since the roof wasn't leaking before the install. For homeowners comparing solar installers, the roof-replacement and EV-charger bundling and the steady run of five-star reviews for the sales and design side are the draw. Given the two recent complaints, it's worth asking specifically who handles technical support after signing and how the company handles a post-install roof issue before committing.

I had the pleasure of working with Tim Matuszewsk at Ecoloop who help me design and install a 13.7kw system - the most efficient for my needs. From start to finish Tim and his team were incredibly responsive and communicative. My electric bill last month was $0.00!!! I would highly recommend working with them.
Juanita y Santiago hicieron un buen trabajo explicándome todo sobre solar, estoy muy satisfecha. Los recomiendo!
I went with this company even though they had slightly higher costs because their salesperson was good, and made me think they would be good at project management throughout. But they are a salesperson and nothing else. They cannot answer technical questions and I have been disappointed at nearly every step. They do not adequately communicate the steps of the process, update you on the status of the project, or give you a realistic timeline start to finish. Do not, seriously, do not support this company.
Great experience across the board! Tim M. was thorough on the proposal and very patient with all my questions throughout the process, and Sandro M. and his team did a heroic job on the install, staying on schedule despite some really brutal weather! A few months in, I've had no issues, and enjoy watching my electric meter running backwards on sunny days.
