But, solar licensing requirements by state vary widely. Some states require a dedicated solar contractor license, while others allow solar installations under an electrical or general contractor license. The exact license you need depends on where the work is performed and whether the project includes electrical, structural, or roofing scope.
Because solar PV systems must comply with the National Electrical Code, states use licensing requirements to ensure installers have the technical knowledge to complete safe, code-compliant installations. Failing to meet licensing requirements by state can delay solar permits, void inspections, or expose contractors to fines and liability.
California has one of the most clearly defined solar licensing frameworks in the U.S. Solar PV installers must hold a C-46 Solar Contractor License, which is specifically designed for solar energy systems. The C-46 license authorizes contractors to:
The requirements for solar panel installations are different depending on the city, county, and state. While several places mandate electrical permits, others require a building permit specifically for solar panels. Certain cities may have a designated permit for solar panels.

For larger utility or commercial scale systems a detailed PV O&M plan prepared by the owner, EPC firm, and/or the developer and accepted by the asset manager is the only long-term operations plan for a PV system.
Large PV power plants (i.e., greater than 20 MW at the utility interconnection) that provide power into the bulk power system must comply with standards related to reliability and adequacy promulgated by authorities such as NERC and the Federal Energy Regulatory Commission (FERC).
The PV O&M cost model allows a customized, if not more accurate, estimate of system cost based on system type and components and on environmental conditions. Survey data on cost and backup service providers are being correlated with model test data to “calibrate” the cost model.
Include decommissioning in the PV O&M plan and/or asset management. The residential and small commercial O&M focus is on fleet performance goals rather than individual systems; meeting performance warranties of individual systems to meet customer satisfaction goals should be balanced against cost and cash-flow optimization.
