Cinnamon Energy Systems reviews

Steve chose Cinnamon Energy after finding a competitive quote and spotting more than 600 successful local permits from the company in his city over the past seven years. He ended up with a sizable residential system: 25 460W solar panels, 25 Enphase microinverters, two Franklin AH2 batteries and an Enphase combiner/switch, and the physical installation took about five days. The crews worked professionally, consulted him through the process, and even cleaned three existing attic-vent solar panels at no extra charge. Marc Shapiro negotiated the contract and guided the project, staying attentive and helping resolve issues as they arose. Early in the process he ran into a layout problem and brought in a friend who specializes in solar design; Cinnamon eventually adopted that friend’s approach (the reviewer refers to it as the Mitchell solution), and their electrical engineer agreed it saved time and money and produced a better install. The permit sequence proved the biggest snag: Cinnamon submitted battery spacing at 3 inches instead of the agreed 3 feet, which created an avoidable delay of more than a month, and the final permission to operate took over six weeks rather than the 5–10 

Jack C. chose Cinnamon Energy twice over a decade — a 6 kWh system in 2014 and an 8.4 kWh system in 2016 — as he moved between two Bay Area homes. He returned because Barry Cinnamon had assembled a steady, capable team that handled everything from home assessment and realistic proposals to the actual installation and follow-up. Barry stayed involved beyond the roofline too, tracking Sacramento energy initiatives and the PG&E rate fights that affect homeowners. Scott O. took close roof measurements — most recently using drone scans — and laid out plausible year‑long energy projections. Christy and Paula kept appointments and callbacks organized and routed questions to the right people, while Jonathan M. and Felipe ran the on‑site work in a personable, professional manner. Scott also spelled out the schedule up front, mapping dependencies like panel lead times, city inspector visits and electrician coordination so the timeline didn’t feel mysterious. In both installs the crew finished within those estimates. The systems performed within expected energy output, and when a separate roofing problem surfaced after installation, Barry’s crew triaged it quickly and completed major roof

Elliot had run the same solar array since 2002 and decided it was time for an upgrade: he planned to replace a single string of panels — roughly a third of his array — because the originals were old and only producing about half their peak output. He met John B., who came out, inspected the site, and reviewed his production data; after that, John agreed that swapping that string made the most sense. John returned a prompt proposal that struck him as the best balance of cost and quality. As an engineer who knows his system well, he asked for LG panels instead of the original suggestion; John offered options, accommodated the request, and handled a couple of minor reconfigurations to integrate the new string. During the work another, unrelated string in Elliot’s older system failed. Cinnamon sent their top technicians back to troubleshoot — even though fixing that hardware hadn’t been part of the plan — and repaired the issue in a few hours. That follow-up service on equipment they hadn’t installed stayed with him as the most notable part of the experience. The upgraded string went in smoothly and the whole system is now back up and producing. What stood out across the job was the

Shannon chose Cinnamon to install a solar-plus-battery system on her new-construction home three years ago. The moment that stands out came when she lost power while getting ready to host 50 people — the system proved reliable and Cinnamon stepped in to help during the outage. Over the past three years they have stayed highly communicative and responsive, answering her questions and following up as needed. Her lasting impression is that the installation was solid and the ongoing support made the difference.

AJ Minich had Cinnamon return to his home to add a ductless heat pump to the solar system they installed several years earlier. Daniel designed the layout so each room gets independent temperature control, which should use far less energy than the old gas furnace and make the household noticeably more comfortable. Cinnamon also removed the old furnace and ductwork as part of the job. He’s eager to see how much warmer the individual rooms are this winter, especially with the room-by-room controls in place.

Till spent more than a year trying to get a 20 kW solar-plus-storage system mounted on his barn roof. Tesla first insisted he replace the roof; after he did, they concluded the roof was too shallow and, after an appeal, told him they could only install 15 kW. Frustrated by the drawn-out process and the downsize, he walked away and hired Cinnamon. Cinnamon showed up on schedule, fitted the system with batteries, and delivered a tidy, high-quality installation. The detail that sticks: after a year of back-and-forth and an unnecessary roof replacement that still left capacity reduced, Cinnamon finished the job promptly and correctly.

In 2021 Dan Gillmor hired Cinnamon Energy Systems to install solar panels and a backup battery for outages on his home. The installation went mostly smoothly, and when a few wrinkles surfaced the crew returned and sorted them out quickly. What he remembered most was the post‑sale support — attentive, timely follow-up that addressed problems after the install and left the system functioning as intended.

About eight years ago Hugh installed a home solar system through Barry Cinnamon. He discovered the array did exactly what Barry promised: reduced his energy bills enough that, recently, he fully recouped the system's purchase price. Even more striking, the system has not required any service during those eight years. Trust mattered in the purchase, and Barry earned it. His takeaway: start with a design meeting at Cinnamon Solar — that planning produced a dependable, cost-recovering system that ran trouble-free for eight years.

Paul G. knew Cinnamon Solar from the company they ran before it was bought, and he appreciated that the same management re-formed a new organization to continue their hands-on approach. He found that the team carried over a clear commitment to doing the job right and on time. About five years ago they installed a solar system on his home; the installation went smoothly, remained trouble-free, and has produced more than enough power to keep his electric bills at zero — a steady, no-drama outcome he still benefits from.
