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

How does A.M. Sun 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 A.M. Sun 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.

A.M. Sun 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 Integrity6.5/10

Reviews about sales and proposal integrity lean positive overall, with many reviewers saying the company was honest, knowledgeable, and accurate in sizing or estimating systems. At the same time, a meaningful minority describe mismatches between what was discussed and what was ultimately delivered, especially around rebate timing, warranty or monitoring expectations, and overall upfront clarity.Solar.com's composite of published customer feedback, not a customer quote

Honest, helpful sales guidance. Several reviewers describe the sales experience as straightforward and customer-focused, saying the team looked out for their interests and seemed to know the product well. Representative review excerpt: "He was honest, and was looking out for my best interests."

Accurate estimates and clear proposals. Some reviewers say the proposal matched the project outcome, including panel counts and system design, which helped set realistic expectations. Representative review excerpt: "Their estimate of the number of panels was spot on."

Watch-outs on promises and expectations. Complaints center on reviewers reporting that certain rebates, warranty terms, or monitoring expectations were not delivered as discussed, which left them feeling the proposal was not fully upfront. Representative review excerpt: "received none of the rebates that their salesman said we would get, they took several months more than was estimated to complete the job and were very hard to get..."

Price & financing transparency

Price Transparency5.3/10

Feedback on pricing and financing is mixed and trends more cautious than other categories. Reviewers praise some financing experiences and say the cost-benefit made sense, but others report deposit problems, unexpected charges, or disagreement over rebate timing and what was included.Solar.com's composite of published customer feedback, not a customer quote

Financing and value can work well. Some reviewers mention using financing successfully and describing the projected cost and benefit as reasonable for their situation. Representative review excerpt: "We went with their financing."

Flexible enough for repeat customers. A few reviewers say they used the company again on another home or that the pricing structure fit more unusual project needs. Representative review excerpt: "We used them at our previous home and our current home."

Concerns about deposits and added charges. Complaints focus on deposits not being returned, charges that were not expected, and disagreements about what was included after the system was installed. Representative review excerpt: "Did not get my $500 deposit back."

Communication & coordination

Communication7.6/10

Communication and coordination are a clear strength overall. Most reviewers describe the team as responsive, organized, and easy to reach throughout the project, though a smaller group reports missed follow-up or slow responses when issues came up.Solar.com's composite of published customer feedback, not a customer quote

Responsive throughout the project. Many reviewers say updates were frequent and communication stayed clear from contract through installation, with multiple team members keeping the project moving. Representative review excerpt: "From the initial contact and contract with Keith, to updates and progress reports from Jeanie, the installers, to customer service from Lacey."

Easy to work with. Reviewers also describe the company as easy to reach and helpful when questions came up, which contributed to a smoother overall process. Representative review excerpt: "Sun Solar was easy to work with and provided great communication during our project."

A few follow-up gaps. The main complaints involve slow or inconsistent follow-up, including cases where customers said they had trouble getting answers or scheduling was not handled well. Representative review excerpt: "Two of my solars broke, I've been trying to contact this company non stop trying to get them to fix and even after 8 months still nothing, every time I..."

Timeline reliability

Timeline Reliability7.2/10

Timeline reliability is generally strong, with many reviewers saying projects finished on schedule or moved quickly once work started. The smaller complaint set points to delays, uncertainty around installation dates, or long waits for specific equipment or follow-up.Solar.com's composite of published customer feedback, not a customer quote

Projects often move quickly. Several reviewers report fast turnarounds from start to finish and say the crew showed up on the scheduled day and completed the work efficiently. Representative review excerpt: "Along with his experienced team, they got the project done in 48 days from start to finish with no hiccups."

Reliable install-day execution. Reviewers also describe the team as prompt and professional once the installation date arrived, which helped keep projects on track. Representative review excerpt: "Prompt, professional, and responsive to our questions and our expectations."

Delay and no-update complaints. A few reviewers say they experienced long waits or could not get a firm installation date, and some report not receiving proactive updates while waiting. Representative review excerpt: "They cannot give me a date for installation and they have not once reached out to me to update or give me any information."

Workmanship & site care

Workmanship8.3/10

Workmanship and site care receive strong marks overall. Reviewers frequently describe professional crews, clean installations, and solid follow-through on inspection-related issues, while a small number raise concerns about placement, cleanup details, or site-specific problems.Solar.com's composite of published customer feedback, not a customer quote

Professional, clean installs. Many reviewers praise the installation team for professional conduct and for leaving the site clean after the job was done. Representative review excerpt: "The install team was professional and completed a spotless install."

Repeat business on more than one project. Some reviewers say they returned for additional projects after a positive installation experience, which suggests confidence in the crew’s workmanship. Representative review excerpt: "I had such a good experience with AM Sun doing our solar power installation I decided to use them to install our EV Charger."

A few placement and site concerns. The main complaints describe concerns about panel placement, site-specific issues, or missed details that customers felt should have been addressed before or during installation. Representative review excerpt: "Your manager who came out after we complained to you at first, said that the panels were not placed in the most effecient location to catch the sun."

Long-term support & performance

Long-Term Support8.4/10

Long-term support and system performance are among the strongest parts of the review profile. Many reviewers say the system continued producing well and that warranty or service support was helpful after installation, though a small group reports difficulty getting repairs or monitoring-related issues resolved.Solar.com's composite of published customer feedback, not a customer quote

Ongoing service after install. Reviewers say the company stayed available after the system was turned on and that they could still call with questions when needed. Representative review excerpt: "Even now I am still in the loop as their customer and can call for questions and I know the person on the other end of the phone has a..."

Systems keep producing well. Several reviewers report strong performance over time, including systems that continued to generate electricity effectively after installation. Representative review excerpt: "The system works great and we’ve been producing all of our own electricity since the system came online."

Repair and monitoring frustrations. A few reviewers report difficulty getting help with broken equipment or monitoring issues, saying follow-up after the sale was slower than expected. Representative review excerpt: "Two of my solars broke, I've been trying to contact this company non stop trying to get them to fix and even after 8 months still nothing, every time I..."

Bottom line: A.M. SUN SOLAR’s reviews are strongest on workmanship, long-term support, communication, and timeline reliability, with many customers describing professional crews and steady post-install service. The main caution areas are pricing transparency and sales/proposal expectations, where some reviewers report issues tied to deposits, added charges, rebate timing, or 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.
