In California, Installers are necessary to have either a common contractors license or a C-forty six Solar Contractors License. This license addresses installations for photovoltaic systems, solar h2o and Area heating, and solar pool heating. Other certifications you need to look out for, none of that happen to be legally https://solarinstallerincalifornia.blogspot.com/2025/05/join-californias-solar-movement-with.html
