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
