Installer profile
Green Muscle Solar
Worth a quote, with one document to demand first. Green Muscle Solar, LLC holds ROC license 328742, a Specialty Residential R-11 Electrical classification, active, first issued May 5, 2020 and renewed through May 31, 2028. The ROC page read on August 26, 2026 shows 0 open, 0 disciplined, and 0 resolved or settled cases. Volume is not a self-claim here: the 2026 Solar Power World Top Solar Contractors list ranks Green Muscle 254th nationally with 3,507.20 kW installed in 2025, and the 2026 Top Solar Installers list ranks it 96th among residential installers. For a company whose BBB record starts October 18, 2019, that is real, independently published output.
The consumer file is small and mostly quiet. BBB rates the company A+, accredited since July 2020, with 2 complaints in the last 3 years and no complaint text published, so the themes cannot be read. The company says it is 100 percent vertical, not a broker or sales agency, with master electricians supervising every install, though it stops short of saying no subcontractors are used. Two details worth knowing. The R-11 classification is residential only, unlike the dual CR-11 that some Valley competitors carry, and the bond behind it is $7,500 rather than the $14,500 a CR-11 requires. And the warranty page problem repeats itself: a team page mentions a full 25-year product and output warranty, which covers equipment, while no workmanship duration or scope appears anywhere in the pages read. Six years in, clean state record, verified volume. Get the bid, then make the workmanship warranty exist on paper before you sign.
The evidence
BBB records a business start of October 18, 2019 and incorporation on November 21, 2019, and the ROC first issued license 328742 on May 5, 2020, so the company is roughly six years old. The about page claims over a decade of solar expertise, but that is a team experience claim, not a company age, and no company-stated founding year was published on the pages read.

The ROC detail page shows 0 open cases, 0 disciplined closed cases, and 0 resolved or settled closed cases, subject to the ROC's disclosure limits, which exclude cancelled, dismissed, and settled-without-corrective-work-order complaints. BBB rates the company A+ with 2 complaints in the last 3 years and 1 closed in the last 12 months, publishes no complaint text, and searches found no government enforcement action.

The 2026 Solar Power World Top Solar Contractors list ranks Green Muscle Solar 254th with 3,507.20 kW installed in 2025 in Arizona as a primary-service installer, and the 2026 Top Solar Installers list ranks it 96th among residential installers on the same figure. That is independent third-party volume, not a company claim.

A team page states the equipment comes with a full 25-year product and output warranty, which is a manufacturer-style equipment term, and no workmanship warranty duration or scope is published on the homepage, about page, or FAQ page read. The only warranty on record is an equipment claim with no stated coverage for the installation work itself.

How to read this
This grade weighs a short but verifiable record: an active license, a near-empty complaint file, and volume a trade publication printed under its own masthead. It does not certify workmanship quality, and it cannot count complaints the ROC chooses not to display. The practical gap is the warranty. Before signing, get the workmanship term in writing with a duration and a named obligor, and confirm who is actually on the roof, since the vertical-operation language does not quite say employees only. Our full rubric, including how our own installation business gets graded on the same scale, is on the methodology page. We are a solar installer and we partner with other solar companies. Grading is structurally separated from revenue; see disclosures.
