Installer profile
Sun Light & Power Solar
Sun Light & Power should be a serious comparison quote for a Bay Area project. Its active CSLB license 326203 carries C-46 Solar, B General Building, and C-10 Electrical classifications and was issued in 1976. That date matches the company's account of being founded by Gary Gerber in 1976. Solar Power World ranks it 206 nationally in its 2026 contractor list and reports 5,956.38 kW installed in 2025. The company also says it is 100 percent employee owned and has delivered more than 3,000 projects across California. Those claims are not a substitute for a contract, but the state history and published volume are substantial.
Do not let the long track record turn the warranty conversation into an afterthought. Sun Light & Power publishes manufacturer warranty terms for equipment such as panels, inverters, and batteries, not a clear company workmanship or labor warranty term. The exact business name did not appear in the CSLB name search, but the active record was verified by entering known license 326203 and reads SUN LIGHT & POWER. Get the labor warranty, roof-penetration remedy, and project responsibility in the signed agreement before you treat this as a finished comparison.
The evidence
CSLB issued license 326203 on October 12, 1976. Sun Light & Power says Gary Gerber founded the company in 1976, and BBB also lists its business start as October 12, 1976. The exact name did not return in the CSLB name search, but the record was verified directly by known license number.

The license page reviewed carried no CSLB complaint-disclosure link. That is a narrow public-record result, because California law limits what CSLB can disclose; it cannot establish that a customer has never complained. BBB gives the company an A+ rating, yet its reviewed complaints page supplies no public count or theme.

In Solar Power World's 2026 contractor rankings, Sun Light & Power is 206 nationally with 5,956.38 kW reported for 2025. The entry categorizes the business as an EPC serving residential, commercial, and industrial work. Solar Power World's 2025 California ranking puts it at 46.
CSLB lists Sun Light & Power as a corporation with active C-46 Solar, B General Building, and C-10 Electrical classifications under license 326203, expiring July 31, 2027. The record lists a $25,000 contractor bond and workers compensation coverage through October 1, 2026.

The reviewed warranty page identifies manufacturer coverage for listed equipment, including panel, inverter, and battery products. It does not publish a Sun Light & Power workmanship or labor warranty term. Equipment protection and responsibility for an installation defect are different questions.

How to read this
The grade reflects deep operating history and evidence that can be checked outside the company's own site. It does not fill in the missing labor warranty. Ask for the full workmanship commitment in the actual proposal, including the duration, exclusions, transfer rules, and process for a roof or electrical defect. Then compare that paper against other bids, line by line. 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.
