How does Nor Cal Solar Construction compare where you live? Rankings are local; an installer that leads one city can trail in the next. See how they rank in your city →

Why this differs from star ratings: most five-star reviews say “great company” and stop, and star averages reward that. These category scores only count reviews with concrete evidence, weighted by recency and the reviewer’s track record. A company can hold a strong star average while specific categories score lower; that gap is usually where the real story is. Categories with more complaints than praise are the questions worth asking any bidder, not necessarily dealbreakers.

Where Nor Cal Solar Construction builds

County-by-county activity from CPUC records through May 2026.

What this data covers: *Counts on this page, including the totals up top, come from investor-owned-utility interconnection records (SCE, SDG&E, PG&E). Work in municipal-utility territory, such as LADWP or city utilities, and outside California does not appear here, so this company's true totals are higher than shown. Unlike the county rankings, this profile also shows counties below the 250-install ranking floor.

Nor Cal Solar Construction reviews: what customers say

An independent synthesis of published customer feedback across Google and Yelp, updated September 28, 2026. Green marks praise, amber mixed experiences, red complaints.

Sales & proposal integrity

Sales Integrity7.1/10

Reviewers most often describe the sales process as clear, straightforward, and low-pressure. The strongest praise centers on direct communication, proposal clarity, and owner involvement, with only one complaint in the evidence set.Solar.com's composite of published customer feedback, not a customer quote

Straightforward proposals. Reviewers say the proposals were easy to understand and that the company explained options in a direct, thoughtful way. Several describe the owner as personally involved in the initial conversation. Representative review excerpt: "We obtained proposals from several solar contractors and decided to go with NorCal Solar because of the way owner Eric communicated with us, and the straightforwardness of his proposal."

Helpful consultative approach. Feedback also highlights a thoughtful review of existing systems and attention to possible pitfalls. That comes through as a consultative sales process rather than a hard sell. Representative review excerpt: "I found them to be honest, responsive, and thoughtful in considering the possible options and pitfalls with what we are attempting to do."

Isolated negative review. One review in the corpus is negative, but it does not provide detailed criticism of the sales or proposal process itself. Overall, complaints in this category appear rare. Representative review excerpt: "Didn’t use the company but I do know you shouldn’t be driving like a jerk in a truck with the company name all over it."

Price & financing transparency

Price Transparency6.7/10

Reviews lean positive on pricing clarity, with a few customers describing the deal as fair or good. There is still a small complaint pattern in the evidence set, so this category reads as positive to mixed rather than uniformly strong.Solar.com's composite of published customer feedback, not a customer quote

Fair deal language. Some reviewers describe the pricing as a good deal and say the team was organized throughout the process. The available feedback suggests the company was generally clear enough for customers to move forward confidently. Representative review excerpt: "They gave me a great deal and were totally on it."

Owner explains the details. Reviewers also note that the owner took time to explain things without making the conversation feel overly long. That points to a relatively transparent early pricing conversation. Representative review excerpt: "They're good ,honest and it's the owner himself and comes over to meet with you for the first time explains everything and he doesn't take too much of your time..."

One complaint in the set. There is one negative review in this category, but it is not specific about pricing mechanics or financing terms. Based on the evidence set, the main issue is limited complaint volume rather than a repeated pattern. Representative review excerpt: "Just because they don't know who I am doesn't mean they didn't provide the solar for my home and No I don't live in Harbor Oregon I have multiple homes..."

Communication & coordination

Communication6.8/10

Most reviewers describe the company as responsive, explanatory, and capable of keeping the project moving. A couple of complaints point to communication gaps and follow-up problems, so the category lands in the positive-to-mixed range.Solar.com's composite of published customer feedback, not a customer quote

Responsive early communication. Several reviewers praise the owner and staff for being responsive, explanatory, and easy to work with during the proposal stage. Follow-up is a recurring positive theme in the feedback. Representative review excerpt: "We obtained proposals from several solar contractors and decided to go with NorCal Solar because of the way owner Eric communicated with us, and the straightforwardness of his proposal."

Crew communication on site. Reviewers also mention that installation staff were willing to answer questions and keep customers informed as work progressed. That suggests solid coordination during active project phases. Representative review excerpt: "Every one of the installation guys have been wonderful and happy to explain any questions we had about going solar."

Communication lapse reported. Two reviews describe contact difficulties, including one saying messages went unanswered for an extended period. Another says the owner later stepped in to take responsibility after office communication issues. Representative review excerpt: "I have tried to contact NorCal leaving messages every day for the past month."

Timeline reliability

Timeline Reliability6.7/10

Reviewers often describe the process as being handled end-to-end, but they also note that solar timelines can run longer than expected. One review mentions a delayed system walkthrough after installation, which keeps this category from reading as fully smooth.Solar.com's composite of published customer feedback, not a customer quote

Project handled through completion. Some reviewers say the company took care of the process and that customers should expect the work to take longer than anticipated. That suggests the team does manage the moving pieces, even if the schedule is not always quick. Representative review excerpt: "Just let the process happen, it takes longer than you think and they take care of it all."

Kept customers updated. A positive review describes the installation crew as personable and says they kept the customer up to date as the project proceeded. This points to decent scheduling communication during the job itself. Representative review excerpt: "We found the NorCal installation crew to be personable and they kept us up to date as the project proceeded."

Delayed walkthrough after install. One reviewer reports not having a walkthrough until months after installation was finished. That is the main timeline-related complaint visible in the evidence set. Representative review excerpt: "When the project was finished, I paid what remained and didn't have a walk through the system until three months down the road after installation."

Workmanship & site care

Workmanship7.2/10

The installation feedback is consistently positive, with reviewers describing professional crews, clear explanations, and solid workmanship. No complaint pattern appears in the evidence set for this category.Solar.com's composite of published customer feedback, not a customer quote

Professional installation crew. Reviewers say the installation crew was personable and happy to explain questions during the job. That suggests a professional onsite experience for customers. Representative review excerpt: "We found the NorCal installation crew to be personable and they kept us up to date as the project proceeded."

Thoughtful system work. Customers also describe the team as capable of looking over an existing system and planning upgrades in a practical way. The feedback reflects a careful approach to installation planning and execution. Representative review excerpt: "They looked over our current system and then came up with a proposal to update the current solar panels, add more panels, install a new inverter and upgraded our AC..."

Well-regarded installation quality. One reviewer says the system had been operating without problems after more than a year, which supports the positive workmanship theme. Another says the installation work was well done. Representative review excerpt: "My system has been in operation for 1 1/2 years now without a single problem."

Long-term support & performance

Long-Term Support7.1/10

Post-install feedback is mostly favorable, with several reviewers reporting strong system performance and helpful follow-up. A small number of complaints mention difficulty reaching the company later on, so support quality appears less consistent than the installation feedback.Solar.com's composite of published customer feedback, not a customer quote

System performance reported positively. Some reviewers say their systems continued performing well after installation, including one customer who reported years of benefits. This is the clearest positive signal in the post-install feedback. Representative review excerpt: "Our 3.5 KW home solar system went online in October of 2014 and we have been seeing the benefits ever since."

Helpful follow-up when needed. Reviewers also describe the owner as available for questions and willing to go above and beyond to ensure satisfaction. That points to a supportive post-install experience for many customers. Representative review excerpt: "He has always made himself available for questions and has gone above and beyond to ensure our full satisfaction."

Service contact complaints. Two negative reviews describe difficulty getting follow-up contact after the sale or installation. The complaint pattern is limited, but it is present in the evidence set. Representative review excerpt: "I have tried to contact NorCal leaving messages every day for the past month."

Bottom line: Across 25 substantive reviews, NOR CAL SOLAR CONSTRUCTION earns a 7.8/10 Solar.com installer score, with strongest feedback around installation quality and generally clear sales conversations. Reviewers also describe some communication, timing, and post-install support issues, but those complaints appear limited relative to the overall volume of positive feedback.

Important context: this chart shows investor-owned-utility records only. Companies that shift work toward municipal-utility territory (LADWP and city power departments) or other states will show declining bars here even while building steadily elsewhere, and 2025-26 records also lag real installation dates. Treat this as a partial window, not the company's full trajectory.

How we built this data

Methodology: Counts are residential PV interconnections in investor-owned-utility territory (PG&E, SCE, SDG&E) per CPUC Rule 21 public records through May 2026. Postal and name variants are merged. Municipal utility territory such as LADWP, Glendale, Pasadena, Burbank, Anaheim, and Riverside Public Utilities is not included in those CPUC counts. Counts show recorded installations, not quality ratings. Reported costs are self-reported on owned-system interconnections. No installer can pay for placement.

Who we are: Solar.com is a solar marketplace — we connect homeowners with installers and earn a fee when projects move forward. These rankings and scores are computed from public installation records and published customer reviews. No installer can pay for placement, and no installer — including those we work with — can pay to change a score.
