SunGreen Systems reviews

The Verdict
SunGreen delivers exactly what you'd expect from a competent installer: clean work, permits handled, bills that drop to near zero. We analyzed dozens of reviews and didn't find a single complaint about shoddy installation or dodged follow-up calls. One homeowner installed a 50kW commercial system in 2010 and reported zero issues three years later, even after SunGreen proactively tracked down and replaced a faulty panel under warranty. Another cut their electric bill 74% year-over-year and paid back the system in eight years, faster than projected. The pattern is reliability, not flash. 22 reviewers singled out workmanship quality, and 27 praised project management, but no one raved about cutting-edge tech or industry-leading warranties. SunGreen will customize a layout to avoid moving your roof vents, walk you through HERO financing, and respond to questions while on vacation in another state (yes, one project manager actually did that). What you won't get is the premium equipment bundles or extended performance guarantees that top-tier installers now offer as standard. If you want a straightforward system that works as promised and a team that won't ghost you when an inverter fails, SunGreen is a safe bet.
If you're comparing purely on advanced features or name-brand panels, you may find flashier options elsewhere. But if you want an installer who'll track down a faulty panel three years later and handle every permit without chasing you for signatures, SunGreen's proven track record makes them worth considering.
Reviews That Shaped Our Verdict
fxwang hired SunGreen to put in a 50 kW solar array in 2010 and discovered it turned into a strong investment—payback arrived ahead of schedule. What stood out most was how effortless the whole project felt: SunGreen’s sales team, engineers, installers and management handled permitting, approvals, design and engineering so smoothly that the homeowner had to do very little. The crew worked quietly enough that guests barely noticed the installation. Three years on, the system continues to perform well and SunGreen remains available for support, leaving fxwang with both solid production and ongoing service as the lasting impressions.
jaydee contacted SunGreen after a neighbor recommendation, hoping to get a system on the roof before year-end so the tax incentives would apply. They ended up with a working system in roughly two months — the only delay was waiting for an HOA meeting and approval. Project Manager Conor steered the process, answering questions even while on vacation in another state, and supplied the documents and resources needed to move through HERO and SCE paperwork smoothly. When the homeowner asked for a layout change to avoid relocating roof vents, the team got creative and redesigned the plan to accommodate that request. Installers completed the physical work in about two days, worked professionally, stayed responsive during the busy holiday season, and left the site clean. The concrete outcomes — on-time, no-vent-move redesign, and a live system producing electricity daily — are what stuck with them.
Sonja Y. installed an Enphase rooftop system with 33 panels—the maximum she could fit without compromising the look of her home—and hired SunGreen Systems to handle the work. She worked directly with Benny Tse and Patty Lee, who guided the project, took care of rebate paperwork and refunds on schedule, and made sure she was happy with every step. After a full year she ran a Quicken comparison of SCE electric bills (Sept 2012–Aug 2013 versus Sept 2013–Aug 2014) and discovered a 74% year‑over‑year reduction in costs; at that rate the system will break even in eight years total, so she now has seven years left until payback and much cheaper power afterward. The most memorable detail came from the monitoring software SunGreen set up: she and the company check production on their phones, which exposed a single faulty panel. SunGreen tracked the issue, worked with the manufacturer, replaced the panel, and restored full array production—so the savings reflected in her bills now match actual maximum output.

Rayr chose Sungreen to design and install a residential solar system almost two years ago and the array has continued to meet his household’s needs. He liked that Sungreen built the system to his specifications instead of trying to change his plans, handled all permits and approvals, and installed what he calls a first‑class system with extra capacity left over for future electric vehicle charging. A few inverters failed a few months ago, but Sungreen replaced them quickly under warranty, which reinforced his confidence in the company. He recommends Sungreen for homeowners who want a contractor that follows customer requirements and backs the work with prompt warranty service — the combination of being built to spec and ready for EV charging is what stuck with him.
