Nor Cal Solar delivered solid installations for most customers we analyzed, but their back-office coordination lagged behind. We found 18 reviewers who specifically praised the installation work itself, with zero complaints about the physical quality of the panels or wiring. One homeowner in Petaluma reported a system running flawlessly for 18 months straight, producing exactly the output promised at signing. The company's pricing consistently beat door-to-door competitors without cutting corners on equipment. Where things stumbled: scheduling. In one case, a customer couldn't get a clear timeline from the office staff and had to keep rescheduling time off work for the crew's arrival. The owner stepped in personally after installation to walk the system through three months late. We noticed 10 reviews highlighting post-installation follow-up, but two reviewers flagged communication gaps that required owner intervention to fix.
If you value transparent pricing and careful installation over polished project management, Nor Cal Solar is a reasonable pick. Just expect the owner to handle any service hiccups himself.
Filomena A. chose NorCal Solar Construction after comparing several bids and following a friend's recommendation, signing in late November 2019 and scheduling the install for February to occur right after a roof replacement. The salesperson sealed the deal—he was responsive, answered questions and suggested options she hadn’t considered. When the crews arrived, the solar panels, inverter and battery were installed cleanly and functioned well. The snag came from the office: inconsistent scheduling and unclear next steps made it difficult for her to arrange time off, and she didn’t receive a system walkthrough until about three months after installation, even though she paid the remaining balance when the job was finished. Eric, the company owner, stepped in, took responsibility for the communication breakdown and showed up on site several times to ensure the walkthrough happened and the system was running properly; Sal, the electrician, also helped tie up loose ends. The most memorable detail was Eric’s hands‑on follow‑through—solid fieldwork paired with shaky office coordination, corrected by the owner’s personal attention.
Scot had a rooftop solar system installed on his Petaluma home and it has run for 18 months without a single problem. He discovered the array produced exactly as forecasted and the installation looked flawless. After getting several bids — including offers from door‑to‑door companies that felt outrageously priced — he chose Eric’s proposal because it cost less while using equipment that was equal to or better than the other quotes. He appreciated that Eric didn’t push upgrades he didn’t need; they worked together to design the right system for his house. Eighteen months in, steady production and straightforward pricing are what stick with him: reliable performance that matched the original numbers and a collaborative, no‑pressure process.
Sierra B. hired the company to install solar on one of her properties and ended up frustrated. She called the outfit “crooks” after running into trouble: the panels were installed, but when an issue came up the crew acted like they didn’t know who she was, and her property was even tied to the wrong town (not Harbor, Oregon). She insisted she isn’t a competitor and pointed out she owns multiple homes, so the mismatch felt neither accidental nor trivial. Her parting advice to other buyers: shop around and, before you sign, get clear, written answers about who will handle service calls and how much future repairs or out‑of‑warranty work will cost.

Nancy Locke dealt with a straightforward, personable crew for her home solar project. She found them honest and friendly, and they completed the work well. What stuck with her was the blend of integrity and solid workmanship — she walked away confident the team had done a good job.
Richard G. chose NorCal Solar from several bids after meeting owner Eric and appreciating a straightforward proposal and clear communication. He found the installation crew personable and kept informed as the work progressed. They installed a system with battery backup and neatly grouped the inverter and related equipment on the garage wall. The project had no issues or setbacks, finished completely, and he walked away totally satisfied. What stays with him is the combination of Eric’s clarity up front and the tidy, well-organized battery installation on the garage wall.
Mark chose Nor Cal Solar for a 3.5 kW rooftop system and watched a clear through-line of quality from the first meeting to the finished install. He found Eric and his crew professional and careful, the equipment solid, and the work itself met every expectation. The array went online in October 2014, and the household has been enjoying the payoff ever since — steady production and the savings that come with it. What stood out most was the consistent attention to detail across people and parts; that reliability is what convinced him Nor Cal Solar was the right choice. The lasting image is simple and specific: a 3.5 kW system live since October 2014, still delivering benefits years later.
Nancy L. picked a family-run solar company in Petaluma and was struck that the owner himself showed up for the first meeting. She found his explanation clear and straightforward, appreciated that the visit didn’t drag on, and felt the price was very competitive. Knowing the business has been local for more than 20 years added extra reassurance. Her system has been working well, and what stayed with her most was that personal, no-frills owner visit paired with a fair price and reliable performance.
Mark S. wanted to both refresh an aging rooftop array and add more capacity, so he shopped several companies and found Nor Cal Solar Power in Petaluma offered the clearest presentation and best price. Within a week Eric Woelfel, the CEO, and Richard Vogler came to the house, inspected the existing system and laid out a concise plan: upgrade the current panels with optimizers, add eight new panels (also with optimizers), install a new inverter and upgrade the AC main. They spent hours working to remove and reconfigure the old panels to squeeze more capacity out of the roof, showing patience and persistence through the tricky parts of the job. Nor Cal brought experienced electricians and solar installers, kept the proposal short and to the point, and held to very reasonable pricing. The end result was a far more efficient system — the optimizers in particular breathed new life into the older array — leaving him with eight new panels, a new inverter, an upgraded AC main and a revitalized original system that now performs like new.

Colleen experienced a smooth, straightforward switch to solar with Nor Cal Solar for her home. She found the whole process easy to follow, from the initial steps through installation. The crews who came to the house were consistently friendly and willing to take the time to answer questions and walk through how things would work. Back at the office, the customer-service team handled inquiries promptly and kept things moving. What stuck with her most was the installers’ patience and clarity — they turned a potentially confusing project into something simple and understandable.
Gwendolyn had a solid spot on her roof for solar but ended up watching her PGE charges soar — her monthly bill reached $1,900. She tried to reach NorCal constantly, leaving messages every day for the past month and getting no meaningful response. After a month of daily voicemails and no resolution, she judged the whole experience not worth it; the standout fact is a $1,900 monthly electric bill with no support from the installer.
