We found a rare installer who answers his own phone and doesn't subcontract. Rob Trezza installed one homeowner's system in 2014, and two years later they were still paying the utility company just $23.75 a month. When that same homeowner moved, they hired him again without shopping around. In 12 reviews praising workmanship, we couldn't find a single complaint about quality or follow-through, and multiple reviewers mention he's still responsive years after installation. His background as a roofer shows in the details: one crew ran conduit inside the house instead of taking the easier exterior route, and another coordinated a full roof replacement alongside the panel install without drama. He handles permits, utility paperwork, and state rebate applications himself, so you're not ping-ponging between departments. One reviewer's system exceeded production goals by 30% in the first year, partly because Rob customized the panel selection instead of pushing a standard package. (Yes, he'll do the math to prove payback periods. Expect spreadsheets.) If you want a bigger company with dedicated project managers, look elsewhere. But if you want the same person who designs your system to show up on your roof and answer texts three years later, this is it.
If you're shopping purely on scale, you'll find installers with larger crews and faster timelines. But if you want the owner on your roof and the same number in your phone for years, Rob's the rare installer who still works that way.
Beachreader ended up choosing CT Solar Power after comparing several installers and design firms, mostly because the company brought both solar and construction experience and offered the kind of responsive, local service that felt missing from the bigger national outfits. He worked directly with owner Robert, who handled the site survey, evaluated the property, put together the proposal, and took care of the paperwork, including the state grant application. Together they even sorted through which panel manufacturer would fit his needs best. More than a year after the system went live, it was outperforming production estimates by 30%, and after he added a heat pump, the panels were covering all of his electric use while cutting heating bills by half. That put him on track to break even in about five years, with Robert’s hands-on approach making the whole project feel straightforward from start to finish.
James had already seen what Rob could do on the family’s old house, so when they moved into a new place, he didn’t bother shopping around for another installer. That earlier solar array had set the bar: careful workmanship, competitive pricing, and the kind of follow-through that made it clear Rob stood behind every part of the job. When it came time to build again on the new home, they went straight back to the same installer, trusting the experience they had already lived through instead of starting over with someone new.
Tim ended up with a solar project where Robert stayed involved from the first design conversation all the way through installation, commissioning, and every follow-up afterward. When anything came up, it was handled fast—usually within a day or less—and he never had to chase subcontractors the way he had with other companies. That kind of hands-on start-to-finish oversight left a strong enough impression that Robert became the person he’d want back on a future home without solar.

Alfie’s solar panel system was installed by Rob about 2.5 years ago, and the standout in the whole experience has been how responsive Rob stayed long after the job was done. When questions came up, he kept answering them, and the original installation itself came in on schedule and within budget. That kind of follow-through two and a half years later is what made the project stick out.

Pete came into the project like a careful shopper, comparing panels, system designs, prices, and installers before settling on Connecticut Solar Power for a home system he meant to own outright. Rob Trezza quickly stood out because his roofing background and solar experience gave him the kind of practical guidance Pete wanted, especially when it came to choosing a panel that balanced performance with price and showing that the investment could pay for itself in under six years. The installation team then proved that attention to detail mattered to them too: instead of taking the easy route and running conduit along the outside of the house, they tucked it inside, then mounted the equipment exactly where they had agreed, securely and neatly. They also carried him through the maze of paperwork and approvals, lining up the home energy audit, roof-structure engineering signoff, CT rebates, inspections, town permits, and final approvals. Two years after the system went live, he had already wiped out electric usage charges, which made the careful planning and clean installation feel even more worthwhile.

Bobwoj49 came away especially impressed with CT Solar Power after having a system installed on an all-electric home in 2014. The standout for him was how professionally the installation was handled and how quietly the system went to work afterward: for the 27 months since it went live, it ran flawlessly. The family had set out to wipe out their monthly Eversource bill, especially during the heating season, and while they still keep a small utility bill open, it has been reduced to just a $23.75 distribution and customer service charge each month.

Peter came into a large solar project expecting the sort of headaches that often come with a big utility-backed installation on a home-sized array, but Rob turned it into a smooth, promise-kept job. Even if his price landed a bit above the big shops, the difference showed up in the details: he found the panels on a cost-effective basis, handled all the permits, and kept pressing Eversource until the utility finally answered. After that bottleneck broke, he got the array built on time, and the whole project moved with a steadiness that made the extra cost feel well spent.
Judy ended up with a solar setup that went well beyond the usual panels on a roof, thanks to Rob at Connecticut Solar Power. He stayed helpful and kind through the process and kept showing up when she needed him, which made the experience feel steady and personal instead of transactional. The system has already delivered substantial savings, and what stands out most is how much confidence she had in trusting him with an advanced installation that continues to pay off.
Lorna had been worried that solar panels might spoil the look of her home, but when Rob Trezza and his crew finished the installation last summer, the system blended in beautifully and actually improved the curb appeal. What stood out to her most was how tidy the team stayed and how carefully they handled every detail, leaving behind a polished result rather than the clunky upgrade she had feared. Now she and her family are looking forward to seeing their electric bill drop close to zero while also knowing the house is doing its part to shrink their carbon footprint.
Long-term satisfaction for Connecticut Solar Power holds steady at 5.0 ★. This is better than 76% of installers we looked at.
Long-term reviews carry the most weight in our methodology because they are most representative of what you should be paying for: a system that will perform for years.
