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

How does Greencube 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 Greencube 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.

Greencube Solar reviews: what customers say

An independent synthesis of published customer feedback, updated September 23, 2026. Green marks praise, amber mixed experiences, red complaints.

Sales & proposal integrity

Sales Integrity7.0/10

Reviewers describe the sales experience as generally helpful and confidence-building, with feedback pointing to clear advice and proposals that matched customer needs. There are not enough complaint signals in this category to show a consistent downside pattern, so the available evidence reads mostly positive.Solar.com's composite of published customer feedback, not a customer quote

Helpful guidance. Reviewers say the sales process included helpful guidance that made it easier to move forward with a solar decision.

Representative review excerpt: "Deciding to go with this company for our solar panel installation was truly one of the best choices we've made."

Price & financing transparency

There were no substantive review signals in this category, so there is not enough evidence to assess how clearly pricing, financing, deposits, refunds, or incentive timing were handled. This section remains neutral because the review corpus did not surface a pattern either way.Solar.com's composite of published customer feedback, not a customer quote

No evidence found. The collected reviews did not provide enough direct detail about pricing or financing to support a substantive summary. Representative review excerpt: "Throughout the entire project, their communication was top-notch, keeping us in the loop at every step."

No clear pattern. Because the corpus contains no category evidence here, there is no documented pattern around final price, deposits, refunds, or incentive timing.

Workmanship & site care

Reviewers consistently describe professional installation work and clean job sites. Feedback highlights efficient crews, smooth installs, and a process that left customers feeling the work was handled carefully.Solar.com's composite of published customer feedback, not a customer quote

Long-term support & performance

Long-Term Support7.0/10

Reviewers generally report positive post-install experiences, including systems that met energy needs and a process that felt smooth after installation. The evidence is favorable, though it is centered more on overall satisfaction than on detailed long-term service or warranty examples.Solar.com's composite of published customer feedback, not a customer quote

Meets energy needs. Reviewers say the system was designed to fit their energy needs well, which points to a positive performance outcome. Representative review excerpt: "Their expertise in commercial solar solutions really shines through, and they crafted a system that fits our energy needs perfectly."

Satisfied outcome. Reviewers report being very pleased after installation, suggesting the system delivered a good overall experience once turned on.

Questions answered. Reviewers also describe the team as knowledgeable and responsive to questions, which supports a positive post-install support impression. Representative review excerpt: "The installation was smooth and efficient, thanks to a professional crew that answered all my questions."

Bottom line: Across 25 substantive Google reviews, GREENCUBE SOLAR’s profile is mostly positive, with especially strong feedback on communication, timeline reliability, workmanship, and post-install satisfaction. The score is less well-defined on price and financing because the review corpus did not surface enough direct evidence in that area, and the lower-scoring categories read more as modestly positive than strongly outstanding.

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.
