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

How does Greencat 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 Greencat 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.

Greencat reviews: what customers say

An independent synthesis of published customer feedback, updated September 28, 2026. Green marks praise, amber mixed experiences, red complaints.

Sales & proposal integrity

Sales Integrity7.0/10

Reviewers mostly describe clear, helpful sales conversations and straightforward explanations of the program and scope. A small number of complaints point to uncertainty around what would be installed and whether expectations were fully aligned.Solar.com's composite of published customer feedback, not a customer quote

Clear explanations. Many reviewers say representatives explained the program clearly and set out the work in a way that was easy to follow. Representative review excerpt: "Tech Oliver provided a clear and thorough explanation of the program and outlined exactly what he was going to do."

Helpful assessments. Some customers describe the initial assessment as thorough and the sales interaction as informative and comfortable. Representative review excerpt: "Oliver with GreenCat did an amazing job with the assessment of my house."

Scope uncertainty. A small number of reviews say the proposal or on-site explanation felt unclear about the exact equipment or attic work that would be included. Representative review excerpt: "Rep was very sketchy not knowing what they were going to put in my attic."

Price & financing transparency

There were no substantive reviews in this category, so the review corpus does not provide enough evidence to summarize pricing, financing, deposits, refunds, or rebate timing. As a result, no score is available here from the analyzed reviews.Solar.com's composite of published customer feedback, not a customer quote

No evidence set. No substantive review evidence was available for pricing or financing transparency. Representative review excerpt: "Oliver with GreenCat did an amazing job with the assessment of my house."

No pricing signal. The corpus does not include enough price-related detail to draw a reliable conclusion about final costs or financing terms. Representative review excerpt: "He was very helpful explaining what the program was about."

Communication & coordination

Communication7.5/10

Most reviewers describe responsive, professional communication and say the team was helpful in answering questions and coordinating work. The complaint pattern is limited but does include reports of slow replies and difficulty getting callbacks.Solar.com's composite of published customer feedback, not a customer quote

Responsive teams. Many reviewers say staff were professional, respectful, and able to answer questions clearly during the project. Representative review excerpt: "This looks better esthetically & is much more efficient (thank u Albert!) I appreciate that they were able to answer all of my questions."

Clean handoffs. Several customers mention smooth coordination with crews who kept the workspace clean and handled multiple tasks efficiently. Representative review excerpt: "Just wanted to say first off the two gentlemen who came and did the work Albert and Daniel were very courteous and kept their workspace clean they were always polite..."

Delayed follow-up. A few reviewers report slow responses and trouble reaching the company when they needed issues resolved. Representative review excerpt: "From a customer perspective—they take forever to respond and resolve issues."

Timeline reliability

Timeline Reliability7.5/10

Reviewers generally say work stayed on schedule, with crews arriving when expected and completing projects efficiently. The available reviews do not show a notable pattern of schedule failures or missed appointments.Solar.com's composite of published customer feedback, not a customer quote

On-time crews. Some reviewers specifically mention that crews arrived on time each day and followed a set schedule. Representative review excerpt: "They were on time every day, followed a set schedule and worked so hard in 100+ degree weather."

Efficient completion. Others describe fast, efficient installation work and timely progress from start to finish. Representative review excerpt: "This guy was very quick with the installation; I was surprised by how fast it was."

Smooth process. Several reviews frame the overall process as timely, including inspection and installation steps. Representative review excerpt: "Oliver was the young man that did the first inspection and he was such a delight to work with."

Workmanship & site care

Workmanship8.9/10

This is the strongest-rated area in the review set, with most customers describing professional crews, clean work, and careful site handling. Complaints are rare, but a small number of reviews mention post-installation issues or equipment problems after the work was done.Solar.com's composite of published customer feedback, not a customer quote

Professional installs. Many reviewers praise the crews for doing clean, professional installation work across a range of home projects. Representative review excerpt: "I had the pleasure to have Martin, Luiz and victor work at my residence and they did a wonderful, professional and clean work."

Careful cleanup. Customers frequently mention respectful crews who cleaned up after the job and kept the workspace orderly. Representative review excerpt: "Ron & team is very professional, clean up after their mess, have pride & joy in what they do, very respectful, and both are very efficient done in a timely..."

Post-install issue. A small number of reviews describe problems after installation, including an equipment-related issue that needed follow-up. Representative review excerpt: "Since they installed the new water heater I have problems with the breakers"

Long-term support & performance

Long-Term Support5.0/10

Reviewers are split between positive post-install experiences and complaints about follow-up support or issues after the system was installed. The praise centers on working equipment and clear explanations, while the complaints point to unresolved service concerns and contractor-related support problems.Solar.com's composite of published customer feedback, not a customer quote

Working as expected. Some reviewers say the installed equipment was working well and that the crew did a good job explaining the completed work. Representative review excerpt: "Sherman did a great job with the Installation he was very Professional and courteous, and the water heater is working great without any issues"

Helpful follow-up. Others describe clear communication and good customer service after installation. Representative review excerpt: "They also took the time to explain the work clearly so I understood everything that was done and the reason for it."

Support concerns. A few reviews mention post-installation problems or broader support concerns, including issues with breakers and contractor turnover. Representative review excerpt: "Since they installed the new water heater I have problems with the breakers"

Bottom line: Across the reviewed Google feedback, GREENCAT is rated strongly for workmanship, with generally positive marks for communication, scheduling, and sales clarity. The main caution areas are limited but real: some reviewers report slow follow-up, and the weakest category is long-term support and performance, where post-install issues appear in a minority of reviews.

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.
