Installer profile

Stellar Solar

B
B grade. A license record dating to 1998, two resolved BBB complaints in three years, and independently listed volume, but no published workmanship warranty term.

Yes, get the quote. The exact legal entity is TMAG Industries Inc, doing business as Stellar Solar Electric, on license 749095, C-10 Electrical only, current and active, issued May 7, 1998 and expiring May 31, 2028. The 1998 founding claim actually checks out, which is rarer than it should be: the company says it, BBB dates the business start to April 1, 1998, and the CSLB issue date lands a month later. The FAQ states that installation crews are company employees, not day-labor subcontractors. Volume is independently listed, not just claimed: Solar Power World ranks it 150 nationally and 24 among installers for 2026 with 12,207.82 kW installed in 2025, and 51 in the 2025 California list with 4,177.29 kW.

The complaint file is short. BBB shows an A+ rating, accreditation since 2006, and 2 complaints in the last three years, both published as Resolved: a $200 microinverter inspection charge followed by a second $200 charge the consumer called bait and switch, and a 2022 panel add-on where an approximately five foot gap put four panels into tree shade sooner, closed after a founding partner called the customers. No complaint disclosure link appeared on the CSLB record when it was read, which means nothing publicly disclosable, not a certified zero. Two watch items. The license flags a workers comp certificate as waiting to be processed, dated August 29, 2026, against a Cypress Insurance policy that expired the same date; that is an administrative flag worth rechecking before you sign. And BBB still lists SunPower by Stellar Solar as an alternate name, so this company previously sold under the SunPower dealer brand. What the end of that relationship means for equipment warranties sold under it was not confirmed by the sources read.

The gap that keeps this from an A is the warranty. The FAQ asserts a workmanship warranty plus manufacturer warranties, but never states the workmanship duration or scope. A service article gives a 1 year workmanship warranty on service work, and the MVP+ lease page says 20 years of service and support. For a purchased system, no published number exists. Ask for the workmanship term in writing and attach it to the contract before comparing this bid against anyone else's.

The evidence

LongevityVerified

The 1998 founding holds up across three independent records: CSLB issued license 749095 on May 7, 1998, BBB dates the business start and incorporation to April 1, 1998, and the company says it has powered homes and businesses since 1998 with the C-10 license held continuously since founding.

Complaints and enforcementVerified

No complaint disclosure link displayed on the CSLB record when read on August 25, 2026, which under CSLB's disclosure rules means nothing publicly disclosable rather than no complaint ever, and BBB shows an A+ rating with 2 complaints in the last three years, 1 closed in the last 12 months, both published as Resolved.

Warranty termsCompany claim

The FAQ says every installation is covered by a workmanship warranty plus manufacturer warranties on panels, batteries, and inverters, but states no workmanship duration or scope; a service article gives a 1 year workmanship warranty on service work, and the SolarLease page says the MVP+ lease includes 20 years of service and support, so no published workmanship term exists for a purchased system.

How to read this

A B here rewards what can be checked: a 1998 license that matches the founding story, a two-complaint record, and volume published by a third party. It does not certify the one thing the company leaves unstated, the workmanship term on a purchased system. Make that number appear in your contract, and ask for the current workers comp certificate given the processing flag on the license record. 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.
