How does Sunsolar U S 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 Sunsolar U S 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.

Sunsolar U S 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 Integrity7.8/10

Reviewers largely describe SunSolar U.S. sales conversations as clear, detailed, and helpful, with several noting careful explanations of the process and proposal expectations. A small number of reviewers report pressure or follow-up behavior that felt aggressive, so the overall pattern is positive but not flawless.Solar.com's composite of published customer feedback, not a customer quote

Clear, detailed proposal discussions. Many reviewers say the sales process included thorough explanations of the system, project steps, and contract expectations. They describe the initial conversations as professional and informative. Representative review excerpt: "Kobi (SunSolar U.S.) came to our house and spent quality time with my husband and I explaining the process of installing solar panels."

Helpful guidance on requirements. Some reviewers report that the company helped them understand HOA compliance standards and project details, which they say reduced delays and confusion. Representative review excerpt: "If it weren't for Kobi, I would not have been able to inform my HOA of the compliance standards and it saved me weeks delays and landscaping costs."

Pressure in follow-up contact. A small number of reviewers describe persistent calls and a more aggressive sales approach, saying they felt pushed to schedule appointments or sign documents. Representative review excerpt: "The sales people all seemed nice aft first, but all ended up rather aggressive and kept calling to schedule appointments and for us to sign a bunch of documents without..."

Price & financing transparency

Price Transparency7.4/10

Reviewers generally describe pricing and financing conversations as straightforward and detailed. The feedback is strongly positive overall, with comments emphasizing upfront cost discussion and attention to financing and project economics.Solar.com's composite of published customer feedback, not a customer quote

Upfront cost explanations. Reviewers say SunSolar U.S. explained pricing clearly and took time to walk through the system, equipment, and financing details before work began. Representative review excerpt: "He showed up at my house and spent a couple of hours to explain the system, its equipments, manufacturers and every details related to price and financing."

Transparent discussion of total cost. Some reviewers report that the company was upfront about costs and that the pricing discussion matched their expectations after their own research. Representative review excerpt: "Kobi was up front about every cost, and he even cared about our financing."

Cost-conscious recommendations. A few reviewers say the company proposed solutions that balanced budget concerns with system performance, including practical equipment choices.

Communication & coordination

Feedback highlights clear updates, quick replies, and help coordinating with outside requirements, while a small number of reviewers mention issues with execution or finish quality.Solar.com's composite of published customer feedback, not a customer quote

Responsive project communication. Many reviewers say calls were returned quickly and that the team stayed responsive throughout the process. They describe the project as smooth and easy to follow.

Timeline reliability

Timeline Reliability7.5/10

Reviewers generally report that SunSolar U.S. kept projects moving and handled permitting and coordination tasks effectively. Most feedback is positive on timing, though a small number of reviews point to delays or execution problems that affected the schedule experience.Solar.com's composite of published customer feedback, not a customer quote

Permit handling and coordination. Reviewers say the company took care of permits with the city and utility, which they felt reduced project friction and helped the job move forward. Representative review excerpt: "When I made my decision, they took care of all the permits with the city and with Southern California Edison."

On-time completion reports. Some reviewers say the team finished commitments on time and kept the schedule they discussed. Representative review excerpt: "They were on time and finished all their commitments."

A few schedule-related concerns. A small number of reviewers mention problems tied to project execution or finish quality that they felt undercut reliability. Representative review excerpt: "Many flaws in the finish."

Workmanship & site care

Workmanship8.1/10

Most reviewers describe the installation crews as professional, clean, and careful, with several saying the final result looked good and performed well. A small number of reviewers report workmanship or finish concerns, so the category is positive overall but not uniformly so.Solar.com's composite of published customer feedback, not a customer quote

Clean, professional crews. Reviewers frequently say the installation crew was on time, professional, and cleaned up well after the job. Representative review excerpt: "Crew was on-time, clean, professional and done in 2 days."

Strong final result. Some reviewers describe the completed system as working well and the installation as meeting their expectations from start to finish. Representative review excerpt: "From the initial quote to the final inspection, SunSolar was professional, prompt, and honest."

Isolated finish and equipment complaints. A few reviewers report flaws in the finish or mention panels that did not work as expected, suggesting occasional site-care or workmanship problems. Representative review excerpt: "Many flaws in the finish."

Long-term support & performance

Long-Term Support5.0/10

This is the weakest-rated category in the review set. Many reviewers still say their systems are producing well, but the complaint pattern centers on post-install service, including difficulty getting repairs or follow-up help when something needs attention.Solar.com's composite of published customer feedback, not a customer quote

Positive production reports. Several reviewers say their systems have been working well over time and that they are satisfied with the production and utility-bill results. Representative review excerpt: "I’ve had a solar system from SunSolar for 10 years now and it is working perfectly."

App-based monitoring after install. Some reviewers mention that they received monitoring tools to track production and consumption after completion, which helped them check system performance. Representative review excerpt: "Upon completion, the owner provided us with an app to track production and consumption in real time, so we can be sure everything is operating as it should."

Service follow-up concerns. A few reviewers report difficulty getting service help after installation, including repeated calls for repairs and slow response on equipment issues. Representative review excerpt: "Still CANNOT get a Service Tech to fix our inverter...."

Bottom line: Across 109 substantive reviews, SunSolar U.S. is described most positively for communication, sales clarity, and installation quality. The main caution area is post-install support, where the review record shows a noticeably weaker pattern around service follow-up and repairs. Overall, the profile is still positive, but the long-term support experience appears more variable than the upfront process.

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.
