In California, Installers are required to have either a standard contractors license or simply a C-46 Solar Contractors License. This license handles installations for photovoltaic systems, solar water and Area heating, and solar pool heating. Stellar Solar’s systems have a 25-calendar year warranty that handles products, energy output, and labor. https://solarcompaniesinfresnoca.blogspot.com/2025/11/power-your-home-and-business-with.html
