Can the utility company deny interconnection based on permit issues?

Permit Requirements and Utility Interconnection

When a solar system is installed on a customer’s property, it’s essential to obtain the necessary permits before applying for interconnection with the utility company. In the United States, for example, the National Electric Code (NEC) requires that solar systems be installed in accordance with local building codes and regulations. This typically involves obtaining permits from the local building department. The permits must be properly executed and recorded, as this serves as proof that the system was installed safely and in compliance with local regulations.

Utility Company Inspection and Permit Validation

During the utility company’s inspection, they will verify that the solar system meets the necessary safety and performance standards. This includes checking the system’s electrical connections, ensuring that it is properly grounded, and verifying that the system is sized correctly for the customer’s energy needs. The utility company will also verify that the necessary permits have been obtained and are valid. If the permits are expired or not properly executed, the utility company may deny interconnection.

Best Practices for Solar Permitting and Interconnection

To avoid interconnection denials due to permit issues, it’s essential to follow best practices for solar permitting and interconnection. This includes ensuring that all necessary permits are properly obtained and recorded, and that the system is installed in accordance with local building codes and regulations. The National Renewable Energy Laboratory (NREL) recommends that solar installers and homeowners work with local authorities to obtain the necessary permits, and that they be prepared to provide documentation and proof of permit compliance during the utility company’s inspection. By taking these steps, solar system owners can ensure a smooth and successful interconnection process.
