How does Sun Light & Power 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 Light & Power 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 Light & Power 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 Integrity6.8/10

Reviewers most often describe the sales and proposal process as clear, knowledgeable, and not overly pushy. A smaller set of reviews raises concerns about design fit, savings expectations, or contract and rebate details, so this category lands positive-to-mixed overall.Solar.com's composite of published customer feedback, not a customer quote

Clear, knowledgeable sales process. Reviewers say the team explained options clearly and came across as experts who were easy to work with. Some also say they did not feel the usual hard sales pressure. Representative review excerpt: "Everything was explained clearly, the work crews were high quality and the job was performed timely and efficiently."

Reasonable proposals and expectations. These reviews suggest the upfront design process often felt grounded and thoughtful. Representative review excerpt: "Here are my criteria for choosing a solar vendor: Long-lived company: ✅ Competitive pricing: ✅ (similar to another bid we got, and in line with local data) Good communication: ✅..."

Fit and contract-detail concerns. Other reviewers report designs that felt undersized or impractical, and some say contract language or rebate timing did not match verbal expectations. Those complaints point to occasional gaps between the proposal and the final outcome. Representative review excerpt: "Shame on us for not understanding the rebate issue as written in the contract, but verbally they had told us they would "take care of the applying for the rebate"."

Price & financing transparency

Price Transparency5.7/10

Feedback on pricing and financing is mixed and leans negative. Some reviewers say costs were explained upfront and handled cleanly, while others report surprise charges, service fees, refund issues, or incentive timing problems.Solar.com's composite of published customer feedback, not a customer quote

Unexpected charges and service fees. Negative reviews describe surprise costs for inspections, extra charges added later in the job, and fees that felt hard to justify. These comments suggest that some customers experienced limited transparency once service or follow-up work was involved. Representative review excerpt: "At the end they charged us an extra $3K to fix a problem THEY caused and help us over a barrel and wouldn't finish the job unless we paid."

Rebate and incentive timing issues. Some reviewers report delays in filing paperwork needed for rebates or incentives, which affected when they received funds. That pattern makes incentive timing an occasional pain point in this category. Representative review excerpt: "10 years ago, they took more than 2 months to file a form that was needed for us to get our $15k rebates from the Feds & state solar incentive..."

Upfront pricing for some projects. Positive reviews say costs were explained clearly and financing was not used to obscure the total price. Representative review excerpt: "They were up front about costs, didn't try to hide things through financing deals, and the installation was done very cleanly."

Communication & coordination

Communication7.1/10

Most reviewers describe strong responsiveness, helpful project managers, and smooth coordination across the job. There are still some complaints about missed appointments, delayed follow-up, and difficulty reaching the office, but they appear less common than the positive feedback.Solar.com's composite of published customer feedback, not a customer quote

Responsive project support. Reviewers frequently say the team was responsive, knowledgeable, and pleasant to work with. Several also mention good communication with project managers and helpful follow-through on questions or repairs. Representative review excerpt: "The Team assigned to us is so responsive, highly knowledgeable, and so pleasant to work with."

Clear coordination across stages. Some customers describe solid handoffs and support from the team throughout the project, including help with repairs and system issues after the initial install. These reviews point to strong ownership of the job from start to finish. Representative review excerpt: "Sun Light and Power helped me repair my solar array when my original installer went out of business and my main inverter failed."

Missed updates and hard-to-reach moments. A smaller group of reviewers reports forgotten appointments, trouble reaching the office, or long email-and-phone exchanges to resolve an issue. Those reviews suggest communication can be inconsistent in some cases. Representative review excerpt: "You get the picture: they forgot the appointment, they didn't do any prep with any of my data, they wasted everyone's time."

Timeline reliability

Timeline Reliability6.8/10

Reviewers often say permits, paperwork, and final activation were handled successfully, with some jobs moving smoothly once underway. Still, a minority report delays, missed appointments, and slower-than-expected scheduling, so timeline reliability is positive but not spotless.Solar.com's composite of published customer feedback, not a customer quote

Permits and paperwork handled well. Positive reviews say the company worked through permits, utility paperwork, and final installation in an organized way. Some customers describe the process as moving efficiently once the project got rolling. Representative review excerpt: "They designed the new system, did all of the PG and E paperwork, obtained the permits, removed our old panels and inverter, and in about 3 days, got the new..."

Successful end-to-end completion. Several reviewers note that the system was completed and activated as expected, with the team taking care of the steps needed to finish the job. These comments suggest dependable execution for many projects. Representative review excerpt: "They helped me find one and then worked with me to get the permits and do the final install."

Delays and no-show complaints. Other reviewers describe slower-than-wanted timelines, missed appointments, and delays tied to service or paperwork. Incentive timing also appears in complaints where paperwork was not filed quickly enough. Representative review excerpt: "10 years ago, they took more than 2 months to file a form that was needed for us to get our $15k rebates from the Feds & state solar incentive..."

Workmanship & site care

Workmanship7.4/10

Workmanship reviews are mostly positive, with many customers describing professional crews and clean, well-executed installs. A smaller number of reviewers report sizing issues, repair disputes, or frustration about how some problems were handled after the fact.Solar.com's composite of published customer feedback, not a customer quote

Professional installation quality. Reviewers commonly describe the crews as professional and the installation work as well planned and neatly executed. Some also say the job was handled carefully across more complex roof layouts or multi-building projects. Representative review excerpt: "Very professionally planned, scheduled, and installed."

Careful cleanup and on-site fixes. A number of customers mention technicians addressing water intrusion risk, rebooting systems, or taking care to clean up and protect the site. These comments support a generally solid workmanship picture. Representative review excerpt: "We moved forward with an appointment and Devon helped us with our system, getting it rebooted and taking care to waterproof several areas where water could have intruded, causing the..."

Repair and sizing disputes. A smaller set of reviews reports installation mistakes, including incorrect equipment sizing or disagreement over how follow-up repairs should be handled. Those complaints show up less often, but they are material when they do occur. Representative review excerpt: "They installed the wrong size inverter and would not work with me to fix the problem."

Long-term support & performance

Long-Term Support8.5/10

This is the strongest category in the review set. Reviewers frequently say systems performed well, issues were resolved quickly, and post-install support remained helpful over time, though a few complaints mention diagnostic fees, repair problems, or equipment issues.Solar.com's composite of published customer feedback, not a customer quote

Strong system performance. Many reviewers say their systems work as designed and continue to produce well after install. Several describe meaningful energy savings or reliable monitoring once the system was turned on. Representative review excerpt: "The system works as designed and for most of the year (minus winter due to nearby trees) we are off the grid, saving us hundreds in electricity charges every month."

Helpful repairs and warranty follow-up. Reviewers also say the company stepped in to troubleshoot, restart, or repair systems after installation. Some customers note that the team was able to resolve problems in a timely way when service was needed. Representative review excerpt: "They got our solar system back up and running, troubleshoot, and resolve any issues in a timely, and quick manner."

Service-cost and repair complaints. A smaller number of reviews describe high diagnostic fees, equipment failures, or systems that stopped working after service. These concerns are present, but they are outweighed by the stronger performance feedback overall. Representative review excerpt: "Apparently getting a ‘diagnostic’ service in 2023 on same system will cost you $2800."

Bottom line: SUN LIGHT & POWER’s review profile is strongest in long-term support and post-install performance, with generally solid marks for workmanship and communication. The most mixed area is price and financing transparency, where reviewers describe both clear upfront explanations and some surprise costs or incentive-timing delays. Overall, the feedback paints a company that often performs well, while still drawing occasional complaints around pricing details, scheduling, and follow-up.

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.
