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

How does Source 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 Source 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.

Source Solar 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 Integrity7.3/10

Reviewers consistently describe Source Solar’s sales approach as honest, low-pressure, and straightforward. The feedback centers on clear roof assessments, fair pricing, and a sense that proposals were framed around realistic expectations rather than aggressive selling.Solar.com's composite of published customer feedback, not a customer quote

Honest roof and site assessments. Reviewers say the company was candid about whether a roof was a good fit for solar and did not push a system when the site did not make sense. Representative review excerpt: "When they initially inspected our roof, they were completely honest with us - they said that they wouldn't want to put solar on a roof that only had a few..."

Trustworthy sales experience. Customers describe the team as honest and trustworthy, with a sales approach that focused on helping rather than pushing a hard sell. Representative review excerpt: "If you are looking for an HONEST and TRUSTWORTHY solar installer that aren't just interested in just selling you solar but are there through the entire process, these are your..."

Fair pricing in proposals. Reviewers also mention fair pricing and say the proposal felt transparent and aligned with the work being offered. Representative review excerpt: "If your looking for an all around HONEST local company source is the way to go Josh showed up , gave me his absolutely HONEST opinion and fair pricing ."

Price & financing transparency

Price Transparency6.8/10

Reviewers generally report that pricing and financing were explained clearly, including loan timing, estimates, and funding logistics. Most feedback is positive, though this is the one category with a complaint signal, so expectations around final cost and timing should still be reviewed carefully.Solar.com's composite of published customer feedback, not a customer quote

Clear explanations of costs and estimates. Reviewers say the team answered questions patiently about billing, production estimates, and energy plan details, which helped them understand the financial side of the project. Representative review excerpt: "We are newbies to the world of solar energy, and they very patiently answered all our questions about the time-of-use energy plan, yearly billing, production and use estimates, the monitoring..."

Financing patience and flexibility. Customers describe Source Solar as patient when financing took time to come together, including cases where outside loan funding moved slowly. Representative review excerpt: "I secured a loan through my credit union and Source Solar was patient with the time it took for the funding."

One complaint signal on pricing expectations. The review set includes a small amount of criticism around pricing expectations and value, so this area reads mostly positive but not completely free of concern. Representative review excerpt: "And if you get enough quotes and do your research you'll see that a lot of installers are trying to sell you subpar panels at a premium price."

Communication & coordination

Communication7.5/10

Reviewers consistently praise Source Solar for responsive communication and active project coordination. Feedback highlights fast replies, clear handoffs, and regular updates that helped customers feel informed through the process.Solar.com's composite of published customer feedback, not a customer quote

Regular project updates. Reviewers say the team kept them posted on each step of the process, which helped reduce uncertainty during the project. Representative review excerpt: "I've heard nightmare stories of the process dragging out for months and months - but they kept us posted on each step of the process, and they were incredibly professional..."

Quick responses. Customers report that messages and calls were answered quickly when questions came up about next steps. Representative review excerpt: "Ryan was quick to respond to texts and phone calls when I had questions regarding the next steps."

Helpful multi-channel communication. Reviewers also describe communication as smooth across phone, text, and email, with project contacts being easy to reach. Representative review excerpt: "He was easy to work with and communicated well on the phone, by text and email."

Timeline reliability

Timeline Reliability7.2/10

Reviewers generally report that Source Solar stayed on schedule and kept projects moving through permits, inspections, and activation. The feedback is strongly positive overall, with occasional notes that outside permitting or utility steps can affect timing.Solar.com's composite of published customer feedback, not a customer quote

Reasonable project pacing. One reviewer describes a two-month path from contract signing to Permission to Operate, while noting that part of the timing depended on factors outside the installer’s control. Representative review excerpt: "We ended up getting a new roof and it took 2 months from signing the contract to receiving Permission to Operate - we know that some of it is out..."

On-time field work. Customers say the crew was on time and kept them informed during installation, which helped the project stay organized. Representative review excerpt: "His team was always on time, and they kept me in the loop with the installation which was very helpful."

Handled inspection hiccups. Reviewers mention small inspection or plan-review issues that were worked through without derailing the project.

Workmanship & site care

Workmanship7.9/10

Reviewers describe the installation crews as professional, efficient, and careful with the worksite. Feedback emphasizes quality electrical work, timely execution, and a smooth install process with little mention of site damage or cleanup issues.Solar.com's composite of published customer feedback, not a customer quote

Professional installation crews. Reviewers say the crews were professional and easy to work with during the install process. Representative review excerpt: "Ryan and Josh were super responsive, able to get to our site quickly and did and excellent job."

Efficient project completion. Customers describe the installation as efficient, with one review noting a very fast turnaround from delivery to final installation. Representative review excerpt: "Ryan and Josh were so professional, efficient (from delivery of the panels to our garage to final installation was 3 days)."

Quality electrical upgrades. Reviewers also praise related electrical panel work and describe the completed upgrades as well done. Representative review excerpt: "These brothers did a wonderful job on upgrading our electrical panel so that we could have a new spa and eventually have solar panels."

Long-term support & performance

Long-Term Support7.4/10

There is limited post-install evidence in the review set, but the available feedback is positive. Reviewers mention helpful follow-up on monitoring and system education, suggesting support did not stop at turn-on.Solar.com's composite of published customer feedback, not a customer quote

Helpful post-install education. A reviewer says the team patiently answered questions about monitoring, billing, and production after the system was installed. Representative review excerpt: "We are newbies to the world of solar energy, and they very patiently answered all our questions about the time-of-use energy plan, yearly billing, production and use estimates, the monitoring..."

Monitoring support. The available review evidence also points to a smooth experience with monitoring setup and day-to-day system visibility after activation. Representative review excerpt: "The monitoring app they installed has functioned perfectly and we are actually hooked on watching our daily intake and lamenting any passing clouds that affect our production."

Bottom line: Source Solar’s review profile is broadly positive, with especially strong feedback on communication, workmanship, and sales honesty. Price and financing are also viewed favorably overall, though that category has the clearest complaint signal in the set. Across 21 substantive reviews, reviewers mostly describe a team that stays responsive and keeps projects moving through installation and activation.

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.
