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

How does Treepublic 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 Treepublic 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.

Treepublic 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 Integrity7.7/10

Reviewers generally describe the sales process as knowledgeable and helpful, with proposals that matched customer goals and, in some cases, flexible adjustments when equipment changed. A smaller set of reviews reports contract or expectation issues, including last-minute changes and confusion about what was initially promised.Solar.com's composite of published customer feedback, not a customer quote

Helpful, knowledgeable sales guidance. Many reviewers say the sales team was responsive, answered questions, and helped them work through system design choices. Several describe a smooth handoff from sales into the project phase. Representative review excerpt: "The sales team Sean is very knowledgeable and helpful; the owner Omar and the project managers were all available to answer my questions'."

Proposal changes handled without extra cost. Some reviewers say the installed equipment differed from the original proposal, but the company upgraded the panels without charging more. Those reviews frame the change as a positive correction rather than a disruption. Representative review excerpt: "When the panels they'd put in the proposal were out of stock, they used slightly better panels at no extra cost."

Occasional expectation mismatches. A few reviews describe frustration when the installed system did not match what had been discussed or when contract details changed close to installation. These complaints are uncommon, but they point to some proposal and expectation-management issues. Representative review excerpt: "The initial installation wasn’t set up for whole-house backup as promised, and communication during that period was frustrating — slow responses, missed follow-ups, and a lot of uncertainty."

Price & financing transparency

Price Transparency7.1/10

Reviewers often describe pricing as fair and say the company helped with rebates and other incentive-related steps. The main complaints involve deposit refunds, rebate or incentive timing, and a few concerns about missing or unclear cost details.Solar.com's composite of published customer feedback, not a customer quote

Fair pricing and follow-up. Several reviewers describe the pricing as fair and say the company stayed engaged after the sale. Some also mention that the team helped them understand bill impacts and financing-related steps. Representative review excerpt: "Fair pricing for the services provided and good follow up from the management of the company throughout the process."

Help with rebates and incentive steps. Reviewers say the company helped with rebate paperwork and other incentive-related coordination. In those accounts, the support continued until the incentive process was completed. Representative review excerpt: "He fell on his sword for initially missing the whole house setup and furthermore brought in a dedicated rep to handle my rebate which ultimately came."

Refund and timing concerns. A smaller group of reviews reports delays or confusion around deposits, rebates, or incentive timing. These comments suggest that the financial details were not always resolved as clearly or quickly as customers expected. Representative review excerpt: "Months later, I received a check refunding my deposit minus the cost of the inspection (per the memo line) with no apology, follow-up call, or explanation."

Communication & coordination

Communication8.5/10

This is one of the strongest categories in the review set. Reviewers frequently describe the team as responsive, informative, and available across sales, project management, and installation coordination, though a small number report slow callbacks or difficulty reaching the company.Solar.com's composite of published customer feedback, not a customer quote

Responsive project support. Many reviewers say they were kept informed through emails, texts, and timely answers to questions. Several describe a dedicated team that stayed involved through the project. Representative review excerpt: "I had a dedicated Team working for me that was informative and responive every step of the way, continually emailing and texting me to keep me in the loop as..."

Good coordination across moving parts. Reviewers often mention permitting, inspections, and utility coordination as areas where the company kept the project moving. These accounts emphasize steady follow-through and clear communication. Representative review excerpt: "As with any solar project, there were a lot of moving parts (permitting, inspections, utility coordination), but they kept things moving and were responsive whenever we had questions."

Some slow or missed responses. A few reviews report difficulty getting callbacks, slow follow-up, or communication that felt muddled during service issues. These complaints are present but limited relative to the overall praise. Representative review excerpt: "The installation process it's self was smooth, timely and professional Where Treepublic plainly sucks is on the communication front and when it comes to service after the initial installation."

Timeline reliability

Timeline Reliability8.0/10

Reviewers mostly describe installations, permitting, and activation as moving along on schedule or with active project management. The complaint pattern is narrower and centers on delays, city-related issues, and occasional last-minute changes.Solar.com's composite of published customer feedback, not a customer quote

Projects kept moving. Many reviewers say the team stayed engaged through permitting, inspections, and utility steps so the project continued to progress. Some specifically mention timely completion and active scheduling support. Representative review excerpt: "As with any solar project, there were a lot of moving parts (permitting, inspections, utility coordination), but they kept things moving and were responsive whenever we had questions."

On-time completion reported. Several reviews say the system was installed and turned on when promised, including before a year-end deadline in one account. Those reviewers describe the timeline as dependable. Representative review excerpt: "Treepublic successfully installed my 7.48 kW solar system before year-end as promised, and the system is now live on Enphase and performing well."

A few delay and scheduling complaints. A smaller set of reviews mentions city issues, inspection-related delays, or short-notice changes before installation. These comments suggest that schedule reliability was not perfect in every case. Representative review excerpt: "Once the correction had been made to the contract and installation was about to commence we were told the afternoon before the installation that the panels we had ordered were..."

Workmanship & site care

Workmanship8.6/10

Reviews are largely positive on installation quality, professionalism, and cleanup. A small number of complaints mention roof damage, leaks, or mounting details that affected appearance or required follow-up repairs.Solar.com's composite of published customer feedback, not a customer quote

Professional installation crews. Many reviewers say the crew was professional and did a clean, quality install. Several describe the work as smooth and well executed. Representative review excerpt: "Despite end-of-year demand, the team prioritized my project, communicated clearly, and delivered clean, professional workmanship."

Good results with roof-related work. Some reviewers say the company handled both solar installation and roof-related work well. These reviews describe the finished job as solid and satisfactory. Representative review excerpt: "We used Treepublic to install our solar panels (and fix the roof at the same time) a few years ago and they did a great job."

Limited workmanship concerns. A small number of reviews report roof leaks, damage during reinstallations, or mounting choices that were not aesthetically ideal. These complaints are relatively uncommon but point to occasional site-care issues. Representative review excerpt: "Each time, I have had the roof repaired, only to have Treepublic damage it again when reinstalling the solar panels."

Long-term support & performance

Long-Term Support8.3/10

Post-installation reviews are mostly favorable, with many customers saying their systems are producing well and that the company stayed involved after turn-on. The main concerns involve hard-to-reach support, repair follow-up, and a few production or warranty-related complaints.Solar.com's composite of published customer feedback, not a customer quote

Systems reported to perform well. Several reviewers say their systems have continued working well long after installation, including multi-year follow-up comments. These accounts suggest strong long-term performance for many customers. Representative review excerpt: "I am writing this review now as a follow-up 4+ years later to state that the system has worked flawlessly since installation and I would still reccomend interested parties to..."

Post-install support and monitoring. Some reviewers say the company kept checking in after installation, monitored performance, and helped with app or billing-related follow-up. That ongoing support is a recurring positive theme. Representative review excerpt: "Post battery installation and subsequent issues with app configuration and redo to include a whole house backup, the company made good on ensuring that the battery system and app were..."

A few warranty and service concerns. A smaller set of reviews reports difficulty reaching support or dissatisfaction with repair and production follow-up. These comments indicate that post-install service was not consistently smooth for everyone. Representative review excerpt: "The system has worked well for about a year, but when tech support issues arise they are reluctant to help, and hard to reach."

Bottom line: Treepublic Solar’s review profile is strongest on communication, workmanship, and long-term system performance, with most reviewers describing responsive project support and solid installation quality. Sales clarity and price transparency are still generally positive, but there are a few recurring complaints around contract expectations, deposits, rebate or incentive timing, and post-install follow-up.

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.
