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

How does Sunworks 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 Sunworks 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.

Sunworks 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 Integrity4.9/10

Reviewers give a mixed picture of Sunworks’ sales and proposal process. Positive reviews describe clear education, easy proposal steps, and projects that stayed within budget, while complaints focus on pressure, contract changes, and expectations that did not match the final outcome.Solar.com's composite of published customer feedback, not a customer quote

Contract and promise concerns. Other reviewers describe problems with sales tactics, contract changes, and benefits not matching what they expected. The complaint pattern suggests concern around how proposals and commitments were communicated. Representative review excerpt: "At this point, we have paid over twenty thousand dollars for a system but are not getting the benefit we were promised and relied upon in going with this company."

Helpful proposal guidance. Some reviewers say the team was easy to work with during the proposal stage and helped explain solar clearly. These accounts describe a straightforward path from quote to project start. Representative review excerpt: "Easy to work with to get the proposal and get moving."

Smooth sales experience. Several reviewers report being educated on solar and having the project completed under budget. These comments present a more organized and responsive sales experience. Representative review excerpt: "Jake, Ben, and the entire team at Sunworks did an exemplary job in educating us on solar, installing our panels, and finishing the project under budget."

Price & financing transparency

Price Transparency4.4/10

Feedback on pricing and financing is mixed but leans negative. Some reviewers say the cost matched the quote or that savings aligned with original projections, while others describe unexpected cost concerns, rebate or incentive timing issues, and uncertainty about what was covered.Solar.com's composite of published customer feedback, not a customer quote

Unexpected cost and coverage concerns. Other reviewers describe concerns about high project costs, items not being covered, and confusion around financing or incentive timing. The complaint pattern indicates that pricing clarity was not consistent across reviews. Representative review excerpt: "I asked how something that cost almost $40,000 could fail in only a handful of years And not be covered."

Cost matched quote. A few reviewers say the final cost matched what was originally quoted. These comments point to a relatively clear pricing process for some customers. Representative review excerpt: "The cost was exactly as quoted."

Savings aligned with projections. Some reviewers report that their savings matched the original agreement projections and reduced their utility bills as expected. These reviews suggest the financial outcome was acceptable for those customers. Representative review excerpt: "The YTD PG&E savings have met the original Agreement Projections, and have been as expected a great savings from the typical monthly Billings, from PG&E etc..."

Communication & coordination

Communication3.4/10

Communication is one of the weakest-rated areas in the review set. While a smaller group of reviewers describe helpful follow-up and personal attention, many more report missed callbacks, unanswered emails, and difficulty getting anyone to coordinate next steps or service.Solar.com's composite of published customer feedback, not a customer quote

Difficulty reaching support. Many reviewers report repeated calls, emails, and texts without response when trying to schedule work or get service help. The dominant complaint pattern is a lack of follow-through and weak project ownership. Representative review excerpt: "When you need your system serviced for warranty work, they do not call back, email or respond to you."

Helpful personal follow-up. Some reviewers say a staff member personally contacted them with updates and helped move issues forward. These accounts describe hands-on coordination after problems arose. Representative review excerpt: "Thanks to Laurie Schaffer, she pitched in and handled all my problems, personally contacted me with updates and after months of problems I think we finally got final approval this..."

Good service follow-through. A few reviewers note that the team checked in after appointments to make sure everything went well. These comments reflect a more attentive customer support experience. Representative review excerpt: "She called after the service appointment to make sure everything went well or if there was anything further Sunworks can do to help."

Timeline reliability

Timeline Reliability4.9/10

Timeline feedback is mixed, with some customers describing quick installs and smooth turn-on, and others describing delays tied to scheduling, inspections, and utility steps. Reviews also mention cases where project timing problems were not clearly explained upfront.Solar.com's composite of published customer feedback, not a customer quote

Delays around scheduling and approvals. Other reviewers describe delays with reinstallation, utility approval, and inspection follow-up, along with concerns that timing issues were not communicated early enough. The complaint pattern centers on inconsistent schedule reliability. Representative review excerpt: "I then asked to get on schedule for reinstall when roof complete - could never get them to call back and put on schedule for reinstallation."

Fast installation experiences. Several reviewers say the project moved quickly once it began, with installation completed in a day or two. These comments suggest Sunworks can execute efficiently when the schedule stays on track. Representative review excerpt: "The Sunworks installation team did a fantastic job and completed the project in two days."

Smooth start-to-finish timing. Some reviewers report that the entire process went smoothly and that the system was installed and running without major delay. These reviews show a more reliable timeline experience for a subset of customers. Representative review excerpt: "The entire process went very smoothly and we are happy so far with the results."

Workmanship & site care

Workmanship6.5/10

Workmanship is the strongest-rated category in the review set, and many customers describe neat, professional installation work and good cleanup. Still, there are complaints about roof damage, incorrect materials or parts, and other site-care concerns that show the experience was not uniformly positive.Solar.com's composite of published customer feedback, not a customer quote

Neat, efficient crews. Several reviewers say installers were quick, neat, and finished the job in a short time. These comments point to a generally professional field crew experience. Representative review excerpt: "Getting the ok to turn on had a little delay with PGE but installers were quick and neat and one day here and gone."

Cleanup and job quality. Some reviewers report that the system worked when the crew finished and that the site was cleaned up well. These reviews describe solid installation follow-through. Representative review excerpt: "The system worked when they were done and they did a good job of cleaning up."

Roof and site damage concerns. Other reviewers describe roof damage and other installation-related problems that required attention afterward. The complaint pattern suggests workmanship was good for many customers, but not consistently free of site impacts. Representative review excerpt: "While they were qualified to install the solar system, they damaged much of the roof around where the system was installed."

Long-term support & performance

Long-Term Support4.9/10

Post-install support and system performance receive mixed reviews, with complaints outweighing praise. Some reviewers report smooth operation and helpful follow-up, but many others describe trouble getting warranty help, unresolved equipment issues, and long waits for repairs or responses.Solar.com's composite of published customer feedback, not a customer quote

Warranty and repair frustration. Many reviewers describe difficulty getting warranty support, unresolved outages or inverter issues, and long waits for service. The main complaint pattern is that after installation, support could be hard to reach and slow to resolve. Representative review excerpt: "We feel absolutely helpless when we see our system isn't working because we know we have to go to battle with this company to honor the warranty on the product..."

Helpful post-service follow-up. A few reviewers say the team checked back after service appointments and made sure everything went well. These comments suggest some customers did receive hands-on support after installation. Representative review excerpt: "She called after the service appointment to make sure everything went well or if there was anything further Sunworks can do to help."

Good ongoing system performance. Some reviewers report that the system kept working smoothly and met their expectations for self-reliance or backup power. These reviews show that performance was satisfactory for part of the review set. Representative review excerpt: "The system is working smoothly and has enabled me to be essentially self-reliant for my electric needs."

Bottom line: Across 101 substantive reviews, Sunworks receives a 4.9/10 headline score, with workmanship rated best and communication rated weakest. Reviewers most often describe problems with responsiveness, support after install, and clarity around pricing or expectations, though some customers report smooth installations and satisfactory system performance.

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.
