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

How does Sun's Free 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's Free 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's Free 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 Integrity7.2/10

Reviewers mostly describe the sales and proposal process as clear, practical, and responsive. A small number of comments raise pricing-clarity concerns, but the dominant pattern is that the team answered questions and adjusted proposals when needed.Solar.com's composite of published customer feedback, not a customer quote

Clear, helpful proposals. Reviewers say the team explained the situation at the site and what was needed in straightforward terms, which helped them feel informed before moving forward. Representative review excerpt: "He came to the house, looked at the panel for what I thought I needed, he told me what was the current situation and what I needed to know and..."

Willing to adjust recommendations. Some reviewers report that the team was open to revisiting equipment choices and working through different proposal options rather than pushing a single approach. Representative review excerpt: "After he'd recommended a charger for my place, I asked him if he would be willing to try a different one and he was willing to work with me on..."

Pricing confusion in one review. A small number of reviewers describe confusion about quoted pricing and what they expected from online research, and one says the discussion felt unprofessional. Representative review excerpt: "When asked about the pricing issues, why it quotes about $2000 when online, people were saying it costs about $500, Kevin was unprofessional."

Price & financing transparency

Price Transparency6.8/10

Feedback on pricing and financing is mostly favorable, with several reviewers describing fair pricing, reasonable quotes, and cost-effective bids. There are also a couple of complaints about price expectations and quote clarity, so this category reads as positive but not spotless.Solar.com's composite of published customer feedback, not a customer quote

Fair and reasonable pricing. Reviewers commonly describe the pricing as fair or the quote as reasonable, and some say the work came in as a cost-effective option for the job. Representative review excerpt: "His prices are very fair and he is completely dependable and stands by his work."

Pricing bid experience. Several reviewers say they received a bid they considered cost-effective, with one noting that the quote compared well against other estimates they collected. Representative review excerpt: "Ben got my Tesla charger installed in no time and was the most cost effective bid from 5 electricians."

Price expectation mismatch. A small set of reviewers report concerns about price differences and said they wanted clearer explanation around how the quoted amount was determined. Representative review excerpt: "When asked about the pricing issues, why it quotes about $2000 when online, people were saying it costs about $500, Kevin was unprofessional."

Communication & coordination

Communication7.6/10

Reviewers generally describe the team as responsive, helpful, and easy to work with throughout the project. Most comments highlight good handoffs and active follow-through, while a small number mention coordination challenges along the way.Solar.com's composite of published customer feedback, not a customer quote

Responsive and helpful. Multiple reviewers say the team was responsive and easy to reach, with communication described as helpful during questions and planning. Representative review excerpt: "Ben was responsive and super helpful."

Good project ownership. Reviewers report that the team stayed engaged through the job and worked through issues until the system was in good shape. Representative review excerpt: "There were many problems along the way but Kevin, Ben, and Pedro worked on my system until I was good."

Handled coordination well. Some reviewers say the team managed permits, installation, and add-on work smoothly and made the process easy to coordinate. Representative review excerpt: "They got us permitted and installed faster than expected and were very easy to work to get our Tesla Powerwall added on to our previously installed solar system!"

Timeline reliability

Timeline Reliability7.1/10

Most reviewers say the project moved faster than expected or stayed on track through permitting and inspection steps. A few comments mention delays or problems along the way, so the section is favorable overall but not uniformly so.Solar.com's composite of published customer feedback, not a customer quote

Faster-than-expected progress. Reviewers often say the work moved faster than they expected, including permitting and installation milestones. Representative review excerpt: "They got us permitted and installed faster than expected and were very easy to work to get our Tesla Powerwall added on to our previously installed solar system!"

Permit and inspection handling. Some reviewers describe the team as organized about filing permits and scheduling final inspections after the install was complete. Representative review excerpt: "Wednesday morning Ben and Pedro came and installed the charger in 4 hours, filed the permit at the City and Thursday morning Kevin scheduled the final inspection with the city..."

Some projects had delays. A small number of reviewers say there were problems or setbacks during the process before everything was resolved. Representative review excerpt: "There were many problems along the way but Kevin, Ben, and Pedro worked on my system until I was good."

Workmanship & site care

Workmanship8.0/10

Workmanship is a clear strength in the review set. Reviewers frequently describe solid installation quality, professional crews, and efficient work, with only one complaint pattern appearing in the evidence.Solar.com's composite of published customer feedback, not a customer quote

Solid installation quality. Reviewers describe the crew’s work as solid and well executed, including projects that involved more complexity than expected. Representative review excerpt: "As I told them, that they did a solid job was reflected in the joke of the the competing East Bay solar company's lead installer that came after them to..."

Professional, efficient crews. Many comments focus on efficient, stress-free installs and say the team handled the job professionally from quote through completion. Representative review excerpt: "The whole process from asking for initial quote to getting it installed was so stress-free that I wish more companies were as efficient like this."

Good on challenging jobs. Several reviewers say the crew handled tricky installations successfully and completed the work to a standard they appreciated. Representative review excerpt: "Pedro, Ben (and I cannot remember the name of the 3rd guy who came later in the day because the job was a bit more complicated than what they expected)..."

Long-term support & performance

Long-Term Support6.8/10

Post-install support and performance feedback is mixed relative to the rest of the profile. Reviewers often say the team returned to fix issues and improve system performance, but there are also comments describing problems that needed follow-up after the job was done.Solar.com's composite of published customer feedback, not a customer quote

Follow-up on issues. Some reviewers say the team came back quickly when a charger or system issue appeared after installation and worked until it was functioning properly. Representative review excerpt: "He went above and beyond for my somewhat tricky job, showing up the next morning when the first charger malfunctioned."

Performance and repair help. Reviewers report that the team identified wiring or equipment problems and helped get systems operating correctly afterward. Representative review excerpt: "Kevin found two problems: over the years one plug on roof had collapsed and my previous solar repair technician had incorrectly wired the inverter."

Post-install problems in a few cases. A small number of reviewers describe ongoing issues along the way that required repeated attention before the system was resolved. Representative review excerpt: "There were many problems along the way but Kevin, Ben, and Pedro worked on my system until I was good."

Bottom line: SUN'S FREE SOLAR’s review profile is mostly positive, with especially strong feedback on workmanship and solid marks for communication and sales clarity. The main soft spot is long-term support and performance, where a few reviewers describe follow-up issues after installation, while pricing and timeline feedback is generally favorable but not perfect.

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.
