CSLB's definition: “A solar contractor installs, modifies, maintains, and repairs thermal and photovoltaic solar energy systems. A licensee classified in this section shall not undertake or perform building or construction trades, crafts, or skills, except when required to install a thermal or photovoltaic solar energy system.” (California Code of Regulations / Business and Professions Code, via cslb.ca.gov).
CSLB's public license file (September 2026) shows 1,051 current C-46 licenses statewide. 62% have a workers' comp policy on file and 34% are filed exempt. 28% are sole owners, 63% corporations and 8% LLCs; 44 were issued in the last 12 months.
Right now 13 C-46 licenses are suspended for workers' comp and 25 for bond problems — a suspended license cannot legally contract.

Any California contractor with employees must carry workers' comp (Labor Code 3700). A license with no employees can currently file an exemption with CSLB; beginning January 1, 2028 (SB 1455), CSLB will require workers' comp for all active licenses, with joint-venture licenses the only exception.
The carrier assigns the WCIRB class based on roof-mounted vs. ground-mounted work and electrical scope.
Every active California contractor license needs a $25,000 contractor license bond on file with CSLB (raised from $15,000 on January 1, 2023). For owners with good credit, the bond commonly costs about $140–$250 a year; price depends mainly on credit.
LLC licenses also need a $100,000 employee/worker bond and liability insurance of at least $1 million (plus $100,000 per member over five, up to $5 million).
