How does Run On Sun 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 Run On Sun 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.

Run On Sun 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 Integrity7.7/10

Reviewers mostly describe Run on Sun’s sales process as clear, knowledgeable, and low-pressure. The main complaint pattern is limited to a small number of reviews mentioning delayed or missing follow-up.Solar.com's composite of published customer feedback, not a customer quote

Clear, knowledgeable guidance. Reviewers frequently say the team explained solar details in a way that was easy to understand and helped set expectations early. Several also describe the process as direct and not overly pushy. Representative review excerpt: "Jim is intimately conversant with the finer points of solar power and explains the detail in ways that any individual can relate to — this builds a great customer relationship."

Hands-on, end-to-end process. Some reviewers like that the same team stays involved through the process rather than handing customers off repeatedly. That continuity is described as reassuring during a complex project. Representative review excerpt: "For one thing, they handle all parts of the process themselves, it's not a sales person who hands you over to the installer, who hands you over to another person."

Follow-up gaps in a few cases. A small number of reviewers report missed follow-up or slower responses after an initial conversation. These complaints appear to be uncommon relative to the overall volume of praise. Representative review excerpt: "I reminded Victoria my plan and was promised to get a response from Jim until the end of day, but nothing."

Price & financing transparency

Price Transparency6.9/10

Feedback on pricing and financing is generally positive, with reviewers saying costs and next steps were explained clearly enough to support confidence in the project. The limited complaint pattern centers on a price coming in higher than expected, often tied to added equipment or scope changes.Solar.com's composite of published customer feedback, not a customer quote

Costs usually explained clearly. Reviewers often describe the pricing conversation as understandable and tied to the work being done. Some also note that they felt comfortable with the purchase because the system benefits were discussed openly. Representative review excerpt: "When installation was complete, Jim provided a helpful binder with information on the PV system and has followed up to ensure that I'm happy with the system thus far."

Helpful information after install. A few reviewers mention receiving a binder or other follow-up materials that helped clarify system details after installation. That kind of documentation is described as useful for staying oriented on the project. Representative review excerpt: "When installation was complete, Jim provided a helpful binder with information on the PV system and has followed up to ensure that I'm happy with the system thus far."

Occasional higher-than-expected total. One reviewer says the final price was a little higher than expected because new racks and equipment were added. This points to a small amount of surprise-cost sensitivity, though it is not a widespread theme. Representative review excerpt: "It was a little pricier than expected, but we ended up with new racks and new equipment which is where the additional cost came in."

Communication & coordination

Communication7.7/10

Most reviewers describe Run on Sun as responsive and willing to stay involved through coordination steps. A few negative reviews mention slow replies or phone-service problems, but they are rare relative to the overall praise.Solar.com's composite of published customer feedback, not a customer quote

Responsive project ownership. Reviewers frequently say the team stayed engaged from the first visit through later follow-up questions. Several describe that kind of hands-on coordination as a major strength. Representative review excerpt: "They were diligent in completing the job in a timely manner and have consistently been responsive to any follow-up inquiries I have had."

Helpful coordination on special issues. Some reviewers report that the team worked through utility-related or site-specific complications directly with them. Those accounts suggest a practical, problem-solving approach to communication. Representative review excerpt: "After numerous efforts by email to explain our needs, Jim and I went to Pasadena Water & Power in person, and he was able to get to a substantial compromise..."

A few communication misses. A small number of reviewers mention unanswered emails or difficulty reaching the office by phone. These complaints suggest occasional communication gaps, but not a dominant pattern. Representative review excerpt: "Jim initially responded quick but then no response with follow up emails regarding site evaluation."

Timeline reliability

Timeline Reliability7.3/10

Reviewers generally say projects moved at a reasonable pace and that crews arrived when expected. Still, a small number of reviews describe substantial delays, so timeline reliability is solid overall but not flawless.Solar.com's composite of published customer feedback, not a customer quote

Often on schedule or prompt. Many reviewers say installers arrived on time and the work moved forward without unnecessary waiting. Others note that jobs were completed within a short period once the project was underway. Representative review excerpt: "Installers arrived on time, were courteous and unobtrusive."

Able to keep projects moving. Some reviewers mention that the team fit them into a busy schedule and still completed the work despite weather or workload challenges. That suggests decent control over planning and execution in many cases. Representative review excerpt: "This was a very busy time for solar installers, and Jim Jenal was able to squeeze us into the schedule, and despite the heavy rains, they got the job done."

Occasional major delay reports. A small number of reviewers report projects running far later than expected. Those reviews indicate that timing problems can happen, even though they appear to be uncommon. Representative review excerpt: "Run from Run On Sun Project was four months late to complete (how does a two month project miss by four months?) and now I'm filing in small claims court..."

Workmanship & site care

Workmanship7.9/10

Installation feedback is mostly positive, with reviewers describing professional crews, good cleanup, and careful handling of site conditions. The limited complaints point to the same issue seen elsewhere in the profile: isolated delays and problem installations that required attention.Solar.com's composite of published customer feedback, not a customer quote

Professional crews and clean job sites. Reviewers often say the installers were courteous, pleasant to have on-site, and left the area tidy at the end of the day. Cleanup and professionalism come through as consistent strengths. Representative review excerpt: "Their crew of installers were a pleasure to have at our house and always left the job site immaculate at the end of the day."

Careful work on reinstallations and fixes. Some reviewers describe the team removing and reinstalling equipment to address roof or system issues. Those accounts suggest a practical, detail-oriented approach to the physical work. Representative review excerpt: "We are in the Pasadena area and reached out to Run on Sun to get our solar panels uninstalled and subsequently reinstalled in order to fix a leak in our..."

A few problematic installations. A small number of reviews mention prior installation problems or extended delays that needed corrective attention. These appear to be exceptions rather than the norm, but they are part of the workmanship record. Representative review excerpt: "Jim came to my house, looked at what the other contractor had done, found all the problems with the current installation in progress, and pointed out everything that needed to..."

Long-term support & performance

Long-Term Support7.6/10

Post-installation feedback is mostly favorable, with reviewers saying the team helped restore performance, answered follow-up questions, and even handled small service issues in person. The only notable negative signal is a rare review touching on system-performance concerns.Solar.com's composite of published customer feedback, not a customer quote

Quick help after installation. Reviewers describe fast turnaround when something needed attention after the system was up and running. In several cases, the team is said to have resolved issues personally and promptly. Representative review excerpt: "They were very efficient and had my system back up and running very quickly."

Helpful follow-up service. Some reviewers mention small post-install problems being handled directly by Jim or the crew. That suggests the company stays involved after the initial turnover. Representative review excerpt: "Recently, I had a small issue with hooking my new wifi system up to the Envoy panel, and Jim came out personally to fix it."

Rare performance concern. One review references issues with system reporting, which points to an isolated post-install performance concern. It stands out as a one-off complaint rather than a broad pattern. Representative review excerpt: "I had electronic issues with the Enphase system not reporting on my solar system performance."

Bottom line: Run on Sun’s review profile is broadly positive across sales, communication, workmanship, and post-install support, with scores mostly in the high-7s to low-8s. The most common issues are occasional follow-up lapses, a few timeline complaints, and a small amount of pricing surprise, but those concerns appear limited relative to the overall praise.

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.
