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

How does Sun Capital Energy 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 Capital Energy 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 Capital Energy 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 Integrity7.0/10

Reviewers generally describe the sales process as patient, responsive, and low-pressure, with several saying the proposal and bid process felt comfortable. There is one complaint about how the customer experience was handled, so the category reads positive overall but not spotless.Solar.com's composite of published customer feedback, not a customer quote

No-pressure sales approach. Several reviewers say the sales team was patient and did not pressure them, which made the proposal process feel comfortable. Representative review excerpt: "Sales people are very patient and make you feel comfortable and no pressure."

Responsive bid process. Reviewers also describe the bid as responsive and workable, with one saying it landed in the middle of the quotes they received. Representative review excerpt: "Their bid was in the middle of all the quotes I received and they were very responsive so I went with them."

Isolated complaint. One reviewer reports a poor experience and says the company did not seem to care about the customer. This appears as a single complaint within an otherwise favorable set of reviews. Representative review excerpt: "First off, I do not write negative reviews lightly and only do so if the company really does not care about the customer (or at least try to make things..."

Price & financing transparency

Price Transparency6.0/10

Feedback on price and financing is mixed. One reviewer describes attractive pricing, but most of the evidence points to concerns about billing, payment handling, or unexpected cost issues.Solar.com's composite of published customer feedback, not a customer quote

Billing and payment concerns. Several reviewers raise concerns tied to charges, deposits, or repayment issues, suggesting that transparency around final costs was not always clear. Representative review excerpt: "On October 24, 2024, I signed a contract with CEO Omar Ramirez to install a Tesla battery in my home solar system, as required by the lender (Wheelhouse credit Union)."

Follow-through on reimbursement. Another complaint describes difficulty getting a reported overcharge addressed, which reinforces the theme of frustration around money handling. Representative review excerpt: "First off, I do not write negative reviews lightly and only do so if the company really does not care about the customer (or at least try to make things..."

Positive pricing mention. One reviewer says the company offered good pricing and describes the overall experience positively. Representative review excerpt: "If you do business with Sun Capital Energy you will find an amazing hard working crew, great leadership, down-to-earth caring people, and all at awesome prices while saving the planet..."

Communication & coordination

Communication7.0/10

Most reviewers describe the company as responsive and easy to reach, with frequent mentions of updates and helpful coordination. A smaller set of reviews reports communication breakdowns, including missed follow-up and dropped handoffs.Solar.com's composite of published customer feedback, not a customer quote

Responsive project updates. Reviewers say staff stayed in touch, provided updates, and were responsive when projects hit delays or needed attention. Representative review excerpt: "After hitting dead end after dead and and facing the potential loss of my NEM 2.0 status, AARON was a breath of fresh air calling and even texting updates."

Helpful team coordination. Several reviews describe the team as responsive to customer needs and easy to work with across the project. Representative review excerpt: "Aaron, Ernesto and Jesh were absolutely responsive to our every need."

Communication breakdowns. A few reviewers report being unable to get timely responses or say the project handoff broke down at important moments. Representative review excerpt: "When it came time to pay me back the over-charged amount they took from me….Vanessa disappeared and would not respond to emails or phone calls."

Timeline reliability

Timeline Reliability7.1/10

Timeline feedback is mostly favorable, with reviewers praising quick installs, on-time crews, and help moving projects through permits and inspections. There are also a few complaints about delays and inspection-related problems, so reliability appears solid but not perfect.Solar.com's composite of published customer feedback, not a customer quote

Fast and on-time installs. Several reviewers say the crew showed up early or on time and completed installs quickly. Representative review excerpt: "Installer showed up early for the installation of my solar set up and the installation was done quickly and amazingly clean tight install."

Permit and inspection support. Reviewers also note help with approvals and inspections, describing the team as useful in pushing the project forward. Representative review excerpt: "Mike was a huge factor in getting this done and moving us a long with his in person help passing the inspections."

Delays and inspection issues. A smaller set of reviews reports long waits, missed steps, or equipment remaining on after an inspection issue, pointing to occasional schedule problems. Representative review excerpt: "Helene, you say we never informed you that your crew left our system on (twice!) even after it had failed inspection."

Workmanship & site care

Workmanship7.8/10

Reviewers frequently praise the installation crew for clean work, professionalism, and leaving the site tidy. Complaint evidence exists, but it is limited relative to the positive mentions of workmanship and cleanup.Solar.com's composite of published customer feedback, not a customer quote

Clean, professional installs. Multiple reviewers describe the installation as quick, clean, and professionally handled. Representative review excerpt: "Installer showed up early for the installation of my solar set up and the installation was done quickly and amazingly clean tight install."

Respect for the property. Others say the crew showed up on time, cleaned up afterward, and even took care to match new equipment to the house. Representative review excerpt: "They were responsive communicated well showed up on time cleaned up and even painted the new equipment that was paintable to match the house."

Installation problems reported. A few reviewers report workmanship concerns, including installation mistakes or incomplete work that later needed attention. Representative review excerpt: "Long story short, It didn’t get completed until end of December and even then, the panels were installed wrong and lacked approval from Edison."

Long-term support & performance

Long-Term Support7.6/10

Post-install feedback is generally positive, with reviewers describing helpful service after activation and support for system issues. Some complaints mention unresolved concerns or service frustrations, so long-term support looks good overall but uneven in a minority of cases.Solar.com's composite of published customer feedback, not a customer quote

Helpful after-install service. Several reviewers say the team remained helpful after the install, including coming back to fix problems and get power working again. Representative review excerpt: "They came right out and helped me fix my problem with my breaker and got my power working at the other half of my house."

Strong overall service experience. Other reviewers say they were happy with the full experience from sales through service and that the team stayed responsive. Representative review excerpt: "From sales to service I interviewed over 5 Solar companies (not to be mentioned) and could not be happier working with Josh (OPs Director), Ernesto, Aaron or Derek the installer..."

Service concerns after turn-on. A few reviewers report dissatisfaction with how post-install issues were handled, including concerns that were not resolved to their satisfaction. Representative review excerpt: "First off, I do not write negative reviews lightly and only do so if the company really does not care about the customer (or at least try to make things..."

Bottom line: Sun Capital Energy’s review profile is generally positive, with stronger marks for workmanship, communication, and post-install support than for pricing transparency. The main recurring concerns involve billing or repayment issues, along with a smaller number of complaints about delays and follow-through. Overall, the review set suggests a company that often performs well, while still showing some unevenness in cost clarity and project handling.

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.
