How does Photon Brothers 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 Photon Brothers 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.

Photon Brothers 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 often describe the sales and proposal process as clear, detailed, and helpful, with several noting that they were walked through options and received comprehensive proposals. The main complaints center on expectations not matching the final project experience, including concerns about missing disclosures, weak follow-up after the sale, and disagreement over incentive-related assumptions.Solar.com's composite of published customer feedback, not a customer quote

Clear proposals and helpful guidance. Many reviewers say the sales team explained options well and provided thorough proposal information, which helped them make an informed decision. Representative review excerpt: "The person that I dealt with, Dustin Oswald, walked me through the process, offered me different options and prepared a proposal which I accepted (the proposal also includes the installation..."

Detailed information up front. Some reviewers describe the quote and planning materials as comprehensive and easy to review online, with enough detail to support the decision-making process. Representative review excerpt: "Really great to work with - the team provided a comprehensive quote with all information available online."

Post-sale expectation gaps. A smaller but material set of reviews says important details were not fully explained before signing, including follow-up expectations and incentive-related assumptions. Representative review excerpt: "For instance, we were never told that we had to program our battery to discharge at least 50% of its capacity daily during peak hours for a two-week period while..."

Price & financing transparency

Price Transparency5.1/10

Reviews on pricing and financing are mixed to negative. Praise centers on teams that explained loan paperwork, incentives, and changing rebate conditions clearly, while complaints focus on rebate timing, incentive eligibility, and customers feeling that the financial picture did not match what they understood at the start.Solar.com's composite of published customer feedback, not a customer quote

Helpful with paperwork and incentives. Some reviewers say the team clearly guided them through loan paperwork and incentive-related steps, including adapting when rebate rules changed. Representative review excerpt: "I was assigned a team that guided the entire process explaining g everything to me clearly and managed everything- from the paperwork for the loan, the incentives, coordinating the site..."

Adapted to rebate changes. A few customers report that the company handled changing rebate conditions well and kept the process moving despite shifting timing. Representative review excerpt: "Took awhile navigating the landscape of changing rebates but they did an excellent job and were very good at adapting."

Rebate expectations not met. Complaint themes include customers saying they were told they would qualify for certain rebates or savings, but later felt those expectations were inaccurate or delayed. Representative review excerpt: "Finally, we were not told the truth about the rebates we would be eligible for (even though we emailed and said "please confirm we will be eligible for these rebates..."

Communication & coordination

Communication6.7/10

Most reviewers describe the team as responsive and easy to reach, with steady updates and helpful handoffs during the project. The complaints tend to focus on slow follow-up, repeated outreach to get answers, and occasional coordination breakdowns after installation or during issue resolution.Solar.com's composite of published customer feedback, not a customer quote

Responsive and easy to reach. Many reviewers say the team answered questions promptly and used calls, texts, or email to keep them updated during the project. Representative review excerpt: "They always answered every questiand either called me back or texted me or email me."

Kept customers informed. Several customers describe the coordination as smooth and stress-free because they received regular updates throughout the process. Representative review excerpt: "He was incredibly responsive and kept me informed every step of the way, which made the whole process smooth and stress-free."

Follow-up gaps after issues. Some reviewers report that getting a response after a problem took repeated emails and persistence, especially when something needed to be revisited after install. Representative review excerpt: "We had connection issues in the beginning where the new installation was not connected properly and it took a lot of convincing and emails to get them to come back..."

Timeline reliability

Timeline Reliability5.8/10

Timeline feedback is mixed. Many reviewers say the company handled permits, inspections, and utility paperwork for them and that installation moved quickly once it began, but others describe long waits for activation, inspection issues, or delays in getting post-install follow-up and payments resolved.Solar.com's composite of published customer feedback, not a customer quote

Permits and approvals handled. Positive reviews frequently note that the team took care of permitting, HOA checks, and utility-related paperwork. Representative review excerpt: "They handled all permissions, HOA checks, permitting and all rebate submissions that they could."

Fast work once underway. Some reviewers say that once the project started, installation moved quickly and the crew left the site clean and ready for inspection. Representative review excerpt: "The crew that came out and installed my system worked very fast and left.No mess.Everything worked perfect passed inspections with no issues."

Delays in activation or follow-through. Complaint themes include long waits after install, repeated follow-up to resolve issues, and cases where inspection or connection steps took much longer than expected. Representative review excerpt: "At best, I will receive the check more than a year after the install, during which time I had to ask again and again and again."

Workmanship & site care

Workmanship8.3/10

This is one of the strongest areas in the review corpus. Reviewers frequently praise the installation crew’s professionalism, speed, cleanup, and inspection readiness, while the smaller set of complaints mentions roof damage, site mess, or installation errors that required correction.Solar.com's composite of published customer feedback, not a customer quote

Professional, clean installs. Many reviewers describe the crews as fast, professional, and careful about leaving the site clean after the work was completed. Representative review excerpt: "The crew that came out and installed my system worked very fast and left.No mess.Everything worked perfect passed inspections with no issues."

Strong hands-on installation teams. Several customers say the installers were helpful and thorough, and that the project was managed smoothly on site. Representative review excerpt: "Photon Bros, service guys were great with installation."

Occasional workmanship problems. A small number of reviews report issues such as roof leaks, mess left behind, or installation problems that needed follow-up attention. Representative review excerpt: "The whole reason I had a new roof put on was to get whatever roofing issues addressed before the panels were put on, now I have a leaking roof, and..."

Long-term support & performance

Long-Term Support8.0/10

Reviewers generally speak positively about post-install support, warranty help, and system performance over time. The main complaints involve repair or service follow-through, roof-related issues, and a few reports that post-install problems took too long to resolve.Solar.com's composite of published customer feedback, not a customer quote

Helpful warranty support. Some reviewers say staff helped them pursue warranty service and stayed involved after the system was installed. Representative review excerpt: "Jake worked very hard on our behalf to obtain warranty service from the manufacturer of our inverter panel, and Lucas was extremely helpful during the installation process."

Good long-term service examples. Positive comments also mention battery replacement visits and systems that continued working well over time. Representative review excerpt: "While it took a while to get going, Photon came yesterday and completed the battery replacement with a Powerwall-3, just as thorough and professional as with the initial project."

Post-install issues needing follow-up. A smaller set of reviews reports persistent service problems or unresolved issues after the system was operating, including roof leaks or failures that required continued attention. Representative review excerpt: "The system is finally working, but have had leaks from the roof every winter."

Bottom line: Photon Brothers’ review profile is strongest on installation workmanship and long-term support, where reviewers frequently praise professionalism, cleanup, and warranty help. The softer spots are pricing transparency and timeline reliability, where some customers describe incentive expectations, activation delays, or follow-up gaps that did not match what they expected at the outset.

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.
