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

How does Sun Solar Electric 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 Sun Solar Electric 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.

Sun Solar Electric 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 Integrity7.5/10

Reviewers mostly describe the sales process as clear, helpful, and low-pressure. The main complaints are rare, but the negative reviews do allege that some proposal or installation details did not match expectations.Solar.com's composite of published customer feedback, not a customer quote

Clear explanations and sizing help. Several reviewers say the team took time to explain the system, review electric bills, and build proposals around actual household needs. These accounts describe a consultative process rather than a pushy sales approach. Representative review excerpt: "They took the time to explain everything in a way that actually made sense, without any pressure."

Custom planning and thoughtful proposals. Reviewers also report receiving tailored system designs and careful walkthroughs that helped them understand the project scope before moving forward. Representative review excerpt: "I was very impressed with the salesman, Steven Bernard, when he went through all of our last years electric bill and calculated our needs."

Rare but serious proposal complaints. A small number of reviews describe disputes about what was promised and what was delivered, including claims that some installation details did not match the original agreement. Representative review excerpt: "Then they stopped answering calls, lied about the details of the installation (for example, we had agreed that six circuits would be on backup power but they installed only four.)..."

Price & financing transparency

Price Transparency7.2/10

There are no complaints in this category in the analyzed set, though a few reviews still frame value in personal budget terms rather than universal affordability.Solar.com's composite of published customer feedback, not a customer quote

Pricing pricing feedback. Reviewers describe a recurring pattern in this area. Representative review excerpt: "Their price was competitive, the workmanship was excellent and their customer service was excellent as well."

Value and bill impact. Some customers say the project helped lower monthly electric costs significantly, which they presented as part of the overall value of the install. Representative review excerpt: "Electric power monthly costs have dropped from $300 - $500+ per month down to $50."

Budget-fit caveat. One review notes that the sizing and cost discussion was helpful, but the quoted project was still outside that customer’s budget range. That is presented as a personal affordability issue rather than a hidden-charge complaint. Representative review excerpt: "Sun Power was great in helping me with sizing and cost, but their cost was way out of my budget range."

Communication & coordination

Communication7.4/10

Most reviewers describe the team as responsive, professional, and willing to stay involved through the project. The complaint pattern centers on follow-up gaps, missed communication, and a few reports that customers had to keep chasing for updates.Solar.com's composite of published customer feedback, not a customer quote

Professional walkthroughs and support. Several reviewers say the team explained the process clearly, answered questions, and handled coordination in a professional way from the start. Representative review excerpt: "Nick from Sun Solar came out and walked us through the process and answered all of our questions and concerns with great customer service and professionalism."

Hands-on project ownership. Reviewers also report that staff stayed engaged when issues came up and worked to make sure the job was completed correctly. Representative review excerpt: "There are always little things that happen with complex systems, but Nick, Jayson, and Mike stick with you and make sure it's right."

Communication gaps on some jobs. A small set of reviewers describe delayed replies, limited updates, or missed appointments, suggesting that coordination was not consistent across every project. Representative review excerpt: "He neither showed up for the appointment nor called to say he wasn't coming."

Timeline reliability

Timeline Reliability7.2/10

Timeline feedback is mostly positive, with many reviewers saying the work happened when promised and on schedule. The limited complaints focus on follow-up delays, inconsistent communication, or appointment issues rather than broad schedule failures.Solar.com's composite of published customer feedback, not a customer quote

On-time work and scheduling. Reviewers frequently say the crew showed up when promised and completed the job on schedule. These accounts frame the project as reliable and well-managed. Representative review excerpt: "They were professional, timely, reasonably priced and most of all showed up when they said they would."

Paperwork and completion on time. Some customers specifically mention that the company handled paperwork and finished the job within the expected timeline. Representative review excerpt: "They took care of all the paper work and completed the job on schedule."

Occasional scheduling misses. A few reviews mention delayed follow-up or no-shows, showing that timeline reliability was not perfect in every case. Representative review excerpt: "I set up an appointment with Jayson to do an estimate on installing an EV charger."

Workmanship & site care

Workmanship8.2/10

Reviewers overwhelmingly praise the installation quality, cleanliness, and professionalism of the crews. Complaints are rare in the analyzed set, and the overall pattern points to careful workmanship with only isolated concerns about follow-through.Solar.com's composite of published customer feedback, not a customer quote

Clean, efficient install crews. Reviewers often describe the crew as punctual, clean, and technically competent during installation. These comments suggest strong field execution and good site care. Representative review excerpt: "Installation was smooth and efficient—the crew showed up on time, kept everything clean, and clearly knew what they were doing."

Strong technical design and fit. Customers also report that the team handled more complex homes and system designs well, including projects involving roof work, battery systems, and older properties. Representative review excerpt: "Jayson, Mike, Page and team did an extraordinary job designing and installing a solar panel and Enphase battery system on my existing (50+ year old) house which challenged other installers."

Isolated follow-through concern. One review notes that after parts were installed, communication became difficult unless the customer kept reaching out. That reads as a process issue rather than a broad workmanship problem. Representative review excerpt: "My project didn't seem that complicated, but when a few parts get installed and then you hear nothing unless you are consistent with emails and phone calls."

Long-term support & performance

Long-Term Support8.4/10

This is one of the strongest categories in the review set. Reviewers frequently say the systems perform well over time and that the company remained involved after installation, with only a small number of complaints about post-install support or equipment concerns.Solar.com's composite of published customer feedback, not a customer quote

Strong system performance. Many reviewers say the system works well, produces as expected, or continues to perform reliably after installation. These comments are consistent with strong long-term satisfaction. Representative review excerpt: "They analyzed our energy use, engineered a system using Enphase technology, and delivered a clean, powerful installation that now fully powers our home."

Ongoing support after turn-on. Some customers note that the team remained available for follow-up work, including later battery additions or later service on previously installed systems. Representative review excerpt: "I have used this firm twice, first for a solar roof panel installation, then 18 months later to add a battery backup system."

Post-install concern in a minority of reviews. A small number of reviewers describe repair or equipment issues after installation, which shows that post-install support was not flawless in every case. Representative review excerpt: "Jayson did some testing with the inverter and determined that it was no longer functioning correctly and that it is just a matter of time and it will totally quit..."

Bottom line: Sun Solar Electric’s review profile is strongest on workmanship and long-term system performance, with most customers describing clean installs and reliable output after turn-on. Sales clarity, pricing, communication, and timing are generally positive as well, though a small number of reviews mention follow-up gaps, missed appointments, or disagreements about what was promised and delivered.

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.
