Here’s the answer in a nutshell. There are seven CSLB license classifications that can legally install photovoltaic solar energy systems. They can include:
- “A” – General Engineering contractors are authorized to install solar energy systems.
- “B” – General Building contractors are authorized to install solar energy systems within the definition of B&P Code section 7057, since a solar energy system constitutes the use of two unrelated building trades or crafts.
- C-4 – Boiler, Hot-Water Heating and Steam Fitting contractors are authorized to perform projects that include solar heating equipment associated with systems authorized by this classification.
- C-10 – Electrical contractors are authorized to perform any solar projects that generate, transmit, transform, or utilize electrical energy in any form for any purpose.
- C-36 – Plumbing contractors are authorized to perform any project using solar equipment to heat water or fluids to a suitable temperature.
- C-46 – Solar contractors install, modify, maintain, and repair thermal and photovoltaic solar energy systems. A licensee in this classification shall not undertake or perform building or construction trades, crafts or skills, except when required to install a thermal or photovoltaic solar energy system.
- C-53 – Swimming Pool contractors are authorized to install solar heating in swimming pool projects.
If you’re looking to install solar systems, or you’re looking for a contractor to install a solar system on your home or building, make sure you have the correct CSLB license classification for the job.
