Installer profile

Semper Solaris

C
C grade. The active multi-trade license, 2012 start, and Solar Power World volume are substantial positives. But 165 BBB complaints in three years is too large to wave away, even for a high-volume installer, and published solar labor terms lack a duration.
Semper Solaris is not a thinly documented operation. California lists one active license with general building, electrical, solar, roofing, and HVAC classifications, while Solar Power World reports 12,867.54 kW installed in 2025 and a national rank of 144 for 2026. That scale gives the company a real operating record. It also gives the complaint count context, but not a free pass. BBB reports 165 complaints in the last three years, with 35 closed in the last 12 months. The CSLB record shows no displayed disciplinary action, and the pending Rojas matter is a labor and PAGA case rather than consumer or regulatory enforcement. Still, a buyer should treat the complaint volume as a service-risk signal, then demand a project-specific escalation path before paying a deposit.

The evidence

LongevityVerified

Semper Solaris says it was founded in 2012. CSLB issued its current license on October 26, 2012, and BBB reports 14 years in business. Those independent timing markers line up with the company's founding statement.

Complaints and enforcementAdverse record

BBB lists an A+ rating and accreditation, but reports 165 total complaints in the last three years and 35 closed in the last 12 months. CSLB displays no disciplinary action or citation, and BBB shows no government-action alert. Rojas v. Semper Solaris Construction Inc. is pending in San Diego Superior Court as a Labor Other Labor action, identified as an employment class and PAGA matter rather than a consumer-protection case. The complaint volume remains a material customer-service concern despite the company's scale.

Verifiable volumeVerified

Warranty termsCompany claim

Semper Solaris says its products and labor are covered by warranties and names a Silfab Enhanced Labor Warranty, but it does not publish a duration or the terms for solar workmanship. It separately says it can offer a 50-year Owens Corning roof warranty, and solar module warranties are manufacturer 25-year coverage. The solar labor obligation still needs a contract document.

How to read this

This is the profile where size cuts both ways. It proves capacity and a serious licensing footprint, while the public complaint count means your own job needs an accountable owner. Ask who handles design changes, inspection delays, roof issues, and post-install service. Put a named escalation contact and response timeline in the deal file. Then read the actual solar labor warranty, not just the product and roof headlines. 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.
