How does Sunwork Renewable Energy Projects 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 Sunwork Renewable Energy Projects 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.

Sunwork Renewable Energy Projects 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 Integrity7.7/10

Reviewers generally describe SunWork’s sales and proposal process as clear, solution-oriented, and transparent. The main theme is that expectations are set up front, though a small number of reviews mention some friction early in the quote process or calendar availability.Solar.com's composite of published customer feedback, not a customer quote

Clear expectations. Reviewers say proposals were straightforward, with services, scope, and customer responsibilities explained clearly before work began. Representative review excerpt: "They set clear expectations on what services they do/don't provide and how I could contribute to reduce the installation time and cost."

Design help and accurate estimates. Several reviewers describe the team as collaborative during design and say the estimates tracked closely with the final project. Representative review excerpt: "They work with you on the design and installation phase, and their estimates are accurate."

Busy scheduling. A small number of reviewers note that getting onto the calendar could take time, even when the overall process felt smooth once booked. Representative review excerpt: "The only downside is that they are busy and getting on their calendar is tough but once you are on their calendar everything is handled very smoothly and transparently."

Price & financing transparency

Price Transparency7.7/10

Reviewers are largely positive about pricing, financing, and incentive timing. They often say the company was transparent about costs and handled rebates or incentives in a way that reduced the amount due up front.Solar.com's composite of published customer feedback, not a customer quote

Reasonable pricing. Reviewers describe the pricing as fair and say they felt the project was competently handled without unexpected cost inflation. Representative review excerpt: "They are thorough, very competent and reasonably priced."

Rebates handled up front. Several reviewers say rebates or incentives were applied before payment, which made the final out-of-pocket amount easier to understand. Representative review excerpt: "$1000's in rebates were subtracted from the total before I had to pay anything."

Incentive timing benefits. Some reviewers note that incentive timing helped reduce the effective cost of the project after the installation was complete. Representative review excerpt: "The HPWH actually cost less after incentives than a gas WH did twenty years ago."

Communication & coordination

Communication8.1/10

Communication is generally described as strong, with reviewers praising responsiveness, follow-up, and guidance through design and installation steps. A few reviews mention slower replies or process requirements when the team was busy, but these comments are limited relative to the overall praise.Solar.com's composite of published customer feedback, not a customer quote

Helpful guidance. Reviewers say the team took time to walk through options, installation details, and maintenance considerations in a patient way. Representative review excerpt: "He was meticulous, patient, technically knowledgeable, and extremely thoughtful in walking through options, installation details, incentives, and long-term maintenance considerations."

Good follow-up. Several reviewers describe clear communication and steady follow-up once a project was underway. Representative review excerpt: "Great communication and follow up!"

Slow replies when busy. A few reviewers report delayed responses or slower coordination during the quoting and scheduling stage, especially when the team was busy. Representative review excerpt: "I subsequently sent them 4 reminders in September and October, but they did not respond to any of them."

Timeline reliability

Timeline Reliability7.8/10

Most reviewers describe the project timeline as reliable once work was scheduled, with installations moving efficiently and expectations set clearly in advance. The main caution is that a small number of reviews mention delays in coordination or activation-related follow-through.Solar.com's composite of published customer feedback, not a customer quote

Efficient installs. Reviewers report that once a start date was set, the installation itself often moved quickly and stayed on track. Representative review excerpt: "A few weeks later we scheduled the work and the whole installation, including extensive electrical work, took only two days."

Clear schedule expectations. Several reviewers say the company was upfront about what it would and would not provide, which helped reduce schedule confusion. Representative review excerpt: "They set clear expectations on what services they do/don't provide and how I could contribute to reduce the installation time and cost."

Some timing delays. A small number of reviewers mention longer waits for availability or follow-up during the permitting, scheduling, or activation process. Representative review excerpt: "They informed me that during the on-site visit that I would hear back in a couple of weeks with their availability to do the installation but despite several persistent follow..."

Workmanship & site care

Workmanship8.7/10

Workmanship is one of the strongest areas in the review set. Reviewers consistently describe the installs as clean, careful, and professionally handled, with only a small number of concerns scattered across the corpus.Solar.com's composite of published customer feedback, not a customer quote

Careful, skilled installs. Reviewers frequently describe the crew as knowledgeable and thoughtful in solving installation challenges. Representative review excerpt: "He was very diligent and did his utmost to come up with solutions that addressed all of our concerns, from installing a condensate pump that did not require a discharge..."

Clean site work. Several reviewers say the finished work was neat and clean, and that the install itself was completed efficiently. Representative review excerpt: "The entire installation was completed in less than a day and as you can see from the photo its a clean install."

Strong overall finish. Customers also describe the final result as impressive and say the crew handled the job professionally from start to finish. Representative review excerpt: "We were incredibly impressed by the work they did and would HIGHLY RECOMMEND them to our friends, family and neighbors!"

Long-term support & performance

Long-Term Support8.3/10

Post-installation support is generally viewed positively, with reviewers saying the team stayed available, helped troubleshoot issues, and offered follow-through after turn-on. A few reviews mention longer waits for service on equipment issues, so the pattern is strong but not flawless.Solar.com's composite of published customer feedback, not a customer quote

Available after installation. Reviewers say the team remained helpful after the install and continued to talk through options even when they were not required to do so. Representative review excerpt: "Even so, Reuben remained available, helped me think through options, and provided support when he had no obligation to do so."

Troubleshooting help. Some reviewers describe the company helping investigate performance questions after the system was running. Representative review excerpt: "We had one instance that we were trying to figure out why the water heater start giving out cold water after several minutes."

Service delays on repairs. A small number of reviews mention delays when service was needed later, especially for component failures or repair scheduling. Representative review excerpt: "Then in June, 2023, another microinverter failed and Marc from SunWork told me in August that they could not get to it until September."

Bottom line: Across 97 substantive reviews, SunWork Renewable Energy Projects earns a strong overall profile, with especially high marks for workmanship and generally positive feedback on pricing, communication, and support. The main recurring cautions are occasional scheduling slowdowns, slower replies when the team is busy, and a few post-install service delays, but complaints are relatively limited relative to the volume of praise.

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.
