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

How does Larsun 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 Larsun 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.

Larsun Solar reviews: what customers say

An independent synthesis of published customer feedback across Yelp, updated September 23, 2026. Green marks praise, amber mixed experiences, red complaints.

Sales & proposal integrity

Sales Integrity7.1/10

Reviewers are generally positive about the sales experience, especially when representatives explain the system clearly and set expectations in a straightforward way. At the same time, a meaningful minority describe pressure, missed expectations, or proposals that did not match what was ultimately delivered.Solar.com's composite of published customer feedback, not a customer quote

Clear explanations. Several reviewers say the sales team took time to explain solar details, feasibility, and panel specifications in a way that felt honest and easy to follow. Representative review excerpt: "Hunter took the time to explain every nuance involved in all the facets of Solar power for our home."

Strong proposal value. Reviewers describe a recurring pattern in this area.

Expectation gaps. Complaints in this category focus on promises that reviewers say were not kept, including slower-than-expected timelines and systems that did not match the original sales discussion. Representative review excerpt: "After I got a few bids they were able to price match and I decided to go with them, they promised a fast time line and they did not deliver."

Price & financing transparency

Price Transparency5.6/10

Feedback on pricing and financing is mixed but leans negative. Some reviewers describe fair or helpful quotes, while many others report surprise costs, unclear billing, or dissatisfaction with how costs were presented and handled.Solar.com's composite of published customer feedback, not a customer quote

Helpful pricing for some. A portion of reviewers say the quoted price felt reasonable for the scope of work, and some describe the overall value as workable for their budget. Representative review excerpt: "With the amount of panels we needed they recommended a new electrical panel and the quote for that was also good."

Unclear added costs. Negative reviews commonly mention unexpected charges or billing concerns after the deal was in place, including added costs that customers say were not clearly explained up front. Representative review excerpt: "This company is shady, they claimed since solar edge is not paying them for labor they have to past that cost on to the customer."

Bill-savings disappointment. Some reviewers say their power costs did not improve as expected after the system was turned on, which led to disappointment with the financial outcome. Representative review excerpt: "In Jan 25 my electric bill shot back upto $350 per month again.im paying $500 for solar and $350 to the electric company."

Communication & coordination

Communication4.7/10

Reviewers often praise individual staff members for being responsive and helpful, but the overall communication picture is inconsistent. Complaints center on difficulty reaching support, repeated handoffs, and weak follow-through during project or service issues.Solar.com's composite of published customer feedback, not a customer quote

Responsive team members. Positive reviews frequently mention prompt replies, patient guidance, and staff who stayed engaged throughout the process. Representative review excerpt: "From the very first call to the completion of our solar installation project, the project manager and the entire crew were incredibly patient, helpful, and responsive."

Quick help when issues arise. Some customers say the company sent help quickly when a problem came up, which they viewed as a sign of solid customer support. Representative review excerpt: "We also appreciated that LA Solar sent someone out quickly when the biggest issue came up, which says a lot about how the company backs its technicians and prioritizes customers."

Support gaps. Negative reviews describe difficulty getting timely updates or reaching the right person, with some customers saying they had to repeat themselves across multiple contacts. Representative review excerpt: "“ It was only few years ago… “we’ll look into it.” High turn over personnel, I have to repeat myself every time I called, there’s new employee."

Timeline reliability

Timeline Reliability5.1/10

Timeline experiences are split. Many reviewers report that projects moved forward smoothly, but a notable share describe delays tied to permits, inspections, cancellations, or slow activation after installation.Solar.com's composite of published customer feedback, not a customer quote

Smooth end-to-end process. Some reviewers say the project stayed on track from first contact through completion and that the system was ready when expected. Representative review excerpt: "From the very first call to the completion of our solar installation project, the project manager and the entire crew were incredibly patient, helpful, and responsive."

Inspection and activation progress. Positive comments also note successful inspection support and timely progress through the post-installation steps needed to get the system operating. Representative review excerpt: "After the system was installed, they had LA SOLAR representative here for the Department of Building & Safety inspection which passed with flying colors."

Delays and cancellations. Complaints focus on projects taking months longer than expected, along with permit problems and canceled appointments that disrupted the schedule. Representative review excerpt: "This is also not my first negative experience with the group, as my install was delayed several months because permits were not filed properly, plus several basic things were missed..."

Workmanship & site care

Workmanship5.8/10

Most reviews about workmanship are positive, with customers frequently describing professional crews and solid-looking installations. Still, some complaints point to missed items, wiring or labeling problems, and foreman or crew conduct that did not meet expectations.Solar.com's composite of published customer feedback, not a customer quote

Professional installation crews. Several reviewers describe the installation team as fast, safe, and professional, with the finished system left looking clean on the home. Representative review excerpt: "And for the installation guys, they were very fast and worked safely on the roof with leaving a professional looking system on my home."

Helpful on-site coordination. Some customers say the crew and project staff were patient and supportive during the installation and follow-up work. Representative review excerpt: "From the very first call to the completion of our solar installation project, the project manager and the entire crew were incredibly patient, helpful, and responsive."

Missed details and workmanship issues. Negative reviews mention missed basic items, wiring or labeling problems, and concerns about the professionalism of some field staff. Representative review excerpt: "In addition, they mislabeled the panel switches and when they came to “fix” the wiring, the installer got electrocuted since the wrong breaker was switched off."

Long-term support & performance

Long-Term Support5.6/10

Post-installation support and system performance draw mixed-to-negative feedback. Some reviewers are satisfied with the system output and warranty-related support, but others report battery, monitoring, or service issues that continued after activation.Solar.com's composite of published customer feedback, not a customer quote

Satisfied with output. A number of reviewers say the system has performed well for them, including one customer who cited strong annual generation. Representative review excerpt: "The system consists of 26 panels and generates about 12MWH of energy per year."

Helpful follow-up support. Positive comments also mention staff who stayed helpful after installation and made the transition feel smoother. Representative review excerpt: "I wanna give a special shout out to Karen as my support provider as he has been instrumental in making this a smooth transition and decreasing my stress level."

Battery and service concerns. Complaints center on monitoring, battery operation, and post-install service problems that some reviewers say were not resolved quickly. Representative review excerpt: "I'm the only person on my block who lost power with solar panels and a battery back up system but it didn't kick in!"

Bottom line: LARSUN SOLAR’s review profile is mixed overall, with stronger feedback on sales explanations and installation professionalism than on pricing clarity, communication consistency, and post-install support. The most common complaints involve unclear costs, delays, and difficulty getting service or follow-up help after the system is installed.

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.
