Installer profile
SunLux
SunLux would grade better if its state file were as clean as its BBB page. The company is real and established: founded January 2015 by Joe Benko, Guillermo Santomauro, and Mike Valencia, self-funded, headquartered in Corona, serving Southern California and Central Texas, and claiming more than 7,000 installations totaling 66.5 megawatts. BBB rates it A+ with 8 complaints in 3 years. The CSLB license, 1008374, is current and active through October 2027. None of that is the issue.
The issue is the citation history. The license carries a public complaint disclosure listing two CSLB citations. The 2023 citation, completed August 29, 2024, found departures from trade standards, departures from plans or specifications, and contracting out of classification. The 2018 citation, disclosed under B&P 7124.6, found departures from trade standards and exceeding the contract amount. Two citations five years apart is a pattern, not a paperwork accident, and our rubric treats state citations as government enforcement with a hard D cap. Neither citation suspended the license, which is why this is a D and not an F.
The out-of-classification finding deserves an extra beat, because the license holds C-10 Electrical only. No C-46 Solar classification appears on the record. The evidence on who does the work is mixed too: the about page says sales, design, engineering, and installation sit under one roof, while one customer review on the company's own warranty page describes the installation crew as a contractor with SunLux. The BBB complaints lean toward service follow-through, an inverter down from July to late September 2024, a $795.64 production guarantee payment unpaid for over 6 months, a $40,000 system reported not working for over a year. If you take a quote here, the citation history is the thing to ask about directly.
The evidence
The company says it was founded in January 2015 by Joe Benko, Guillermo Santomauro, and Mike Valencia, BBB dates the business start and incorporation to January 29, 2015, and CSLB issued license 1008374 on October 22, 2015. Three sources land within nine months of each other, which is about as tight as founding evidence gets.

CSLB displays a complaint disclosure on the license with two citations: citation 2 2023 001982, completed August 29, 2024, for departing from trade standards, departing from plans or specifications, and contracting out of classification, and citation 2 2018 001351 for departing from trade standards and exceeding the contract amount. BBB separately rates SunLux A+ with 8 complaints in 3 years, mostly outages, unpaid production guarantee payments, and delays.
The homepage claims more than 7,000 solar installations and 66.5 megawatts across Southern California and Central Texas. No SunLux entry appears in the 2026 Solar Power World national list, the 2025 California list, or the 2026 installer list, so the volume figure rests on the company's own statement.

CSLB lists SUNLUX as a corporation on license 1008374, current and active with a C-10 Electrical classification only, issued October 22, 2015 and expiring October 31, 2027, with a $25,000 bond and workers compensation through May 21, 2027. No C-46 Solar classification appears, which is worth reading next to the 2023 citation for contracting out of classification.

The company's warranty page states a 25 year comprehensive warranty on components and says SunLux guarantees installation, parts, and maintenance. No workmanship duration separate from the component warranty is stated, so ask the contract to spell out what labor coverage survives and for how long.

How to read this
The D here is a rubric cap, not a claim that every SunLux job goes wrong. An active license, an eleven year history, and a BBB A+ all sit on this record too. But state citations are the strongest adverse signal a contractor file can carry short of suspension, and two of them, one involving work outside the licensed classification, put a floor under the caution. Ask who physically installs your system, which classification covers each part of the scope, and what the citation history changed in their process. 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.
