What role does a solar contractor play in the permitting process?

Gathering Necessary Documents and Information

A solar contractor’s involvement in the permitting process begins with gathering all necessary documents and information required by local authorities. This typically includes the property owner’s identification, plot plan, and electrical plan. The contractor must also calculate the system’s electrical load and determine the required number of panels, inverter, and other components. For example, according to the National Electric Code (NEC), a residential solar system typically requires a 200-amp electrical service panel.

Submitting Permit Applications and Scheduling Inspections

Once all necessary documents are collected, the solar contractor submits a complete permit application to the local authorities. The permit application must include detailed information about the solar system, such as the number of panels, inverter type, and mounting system. After submitting the application, the contractor schedules an inspection with the local electrical inspector to verify the system’s compliance with local regulations. The inspector will check the system’s electrical connections, grounding, and mounting to ensure safety and code compliance.

Ensuring Compliance and Obtaining Final Approval

During the inspection, the solar contractor must be prepared to address any issues or concerns raised by the inspector. This may involve making adjustments to the system, such as relocating a panel or modifying the electrical connections. Once the inspector has deemed the system compliant, the contractor will obtain final approval and certification of the solar installation. In some jurisdictions, the contractor may also need to provide a certificate of completion and a copy of the final inspection report to the property owner.
