#415 of 678 scored in California by Solar.com Installer Score

How does Calpro Solar 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 Calpro Solar 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.

Calpro Solar 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 Integrity6.8/10

Reviewers describe a sales experience that is generally clear and low-pressure, with strong marks for explaining the process and answering questions. The available reviews do not show a broad pattern of complaints in this category, but the score sits just below the stronger categories overall.Solar.com's composite of published customer feedback, not a customer quote

Clear explanations. Reviewers say the team took time to explain the process, answered questions, and followed up when something needed clarification. Representative review excerpt: "She would explain the nuances of the process and any questions I posed she answered and more importantly if she wasn't clear on a matter she's solicit the answer and..."

Low-pressure approach. Reviewers also describe the sales approach as friendly, professional, and not pushy. Representative review excerpt: "George and his team are knowledgeable, super friendly, easy to work with, no sales pressure, and very professional."

Price & financing transparency

Price Transparency6.5/10

Feedback on pricing and financing is positive overall, with multiple reviewers saying the quote was reasonable or that the final cost matched expectations. There are also a couple of complaints tied to billing and price clarity, so this category reads as mixed rather than uniformly strong.Solar.com's composite of published customer feedback, not a customer quote

Reasonable quote. Several reviewers say the pricing felt fair, including comments that the quote was reasonable and that the company stood by it. Representative review excerpt: "Gave a reasonable quote and stuck by it."

Cost expectations. Reviewers describe a recurring pattern in this area. Representative review excerpt: "They care about their customers, get their work done on time, are responsive and the cost of their solar system is a fraction of what others charge."

Billing clarity concern. A smaller number of reviewers report confusion around invoicing or not getting a clear price for labor and time right away. Representative review excerpt: "I even had to remind him to actually invoice me for his time as he had not bothered to give me a price for his labor and time (the warranty..."

Communication & coordination

Communication7.2/10

Communication is one of the stronger themes in the review set, with many reviewers describing responsive updates, clear handoffs, and active coordination with related contractors. A small number of reviews mention a communication lapse or a need for the customer to follow up, but those comments are outnumbered by praise.Solar.com's composite of published customer feedback, not a customer quote

Responsive updates. Reviewers frequently say the team was responsive and kept them informed during the project. Representative review excerpt: "They care about their customers, get their work done on time, are responsive and the cost of their solar system is a fraction of what others charge."

Coordinated handoffs. Some reviewers note that the company communicated well with roofing contractors, sent contracts promptly, and handled permits and scheduling quickly. Representative review excerpt: "George promptly communicated with my roofing contractors, emailed a contract and had the permits and service date within 3 days of communication."

Follow-up needed. One reviewer says they had to initiate contact to get payment handled and receive after photos, though the team responded once asked. Representative review excerpt: "I guess if I were to nit pick, my only observation was that I had to call them to pay and get the after pictures but were prompt once requested."

Timeline reliability

Timeline Reliability7.1/10

Timeline feedback is mostly positive, with reviewers describing projects that moved forward on schedule and included prompt permit or service-date coordination. There is one complaint-style review in the set, so the overall picture is good but not flawless.Solar.com's composite of published customer feedback, not a customer quote

Prompt scheduling. Reviewers say permits and service dates were arranged quickly and that the company generally kept projects moving. Representative review excerpt: "George promptly communicated with my roofing contractors, emailed a contract and had the permits and service date within 3 days of communication."

Work completed on schedule. Several reviewers describe the work as being completed on time or in a tight sequence across the roof replacement steps. Representative review excerpt: "Took our roof off in one day, put the new one on in a day, and made final adjustments on a third day."

Schedule frustration. One review reflects a timing complaint tied to project management and delay concerns. Representative review excerpt: "The crew was telling me that their project manager Abraham is a joke he’s focused on building his house in Flagstaff Arizona."

Workmanship & site care

Workmanship7.0/10

Most reviews describe professional crews, careful roof work, and responsive follow-through when issues came up on site. A couple of negative reviews raise concerns about communication around work details and one serious unresolved installation complaint, so workmanship feedback is positive but not uniformly clean.Solar.com's composite of published customer feedback, not a customer quote

Professional crews. Reviewers describe crews as professional and courteous, with installers taking pride in the work. Representative review excerpt: "Our project manager, Luis, communicated well with us throughout our project and his crew was professional and courteous."

On-site follow-through. Some reviewers say the team checked on the roof more than once and applied an interim fix when weather created a problem. Representative review excerpt: "Cal Pro came out a few times to check on the roof, and even applied an interim solution when I was unavailable and the rain came."

Work quality complaint. A smaller number of reviews describe major dissatisfaction with the installation outcome or with how work details were communicated. Representative review excerpt: "I had no roof lots of water damage they took my $10,000 and never did the job."

Long-term support & performance

Long-Term Support7.2/10

Post-install support appears positive in the limited review set, with reviewers describing help troubleshooting equipment and assistance getting replacement parts through warranty channels. There is one complaint-style comment about comfort and identification during a repair visit, but it does not outweigh the supportive reports.Solar.com's composite of published customer feedback, not a customer quote

Warranty help. Reviewers say the company helped troubleshoot a battery issue and worked to get a replacement through the manufacturer warranty. Representative review excerpt: "Though CalPro was not obligated to do it, they came over, troubleshoot the battery, and was able to get a replacement through the manufacturer's warranty."

Ongoing support. One reviewer describes the team stepping in after another provider was no longer available, with the system continuing to operate under warranty context. Representative review excerpt: "He had installed Solar with backup battery two years ago through Sungrade based out of Walnut Creek with 25yrs warranty and they went out of Business last year apparently."

Service visit concern. One review raises a concern about identification and comfort during a repair visit. Representative review excerpt: "I was also assured that company identification will be provided so customers would feel safe letting a non English speaking repairman into their home."

Bottom line: CALPRO SOLAR’s review set is strongest on communication, coordination, and general post-sale support, while pricing and workmanship are more mixed. The overall Solar.com installer score of 7.9/10 fits a profile with many positive experiences and a smaller number of complaints concentrated around billing clarity, scheduling, and installation follow-through.

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.
