When are solar inspections conducted during the installation process?

Inspection Before Racking Installation

Solar inspections are often conducted before the racking system installation to ensure that the mounting system is properly sized and compatible with the solar panels. This is usually done by the permitting authority or a certified solar inspector. A typical solar inspection checklist during this stage will include verifying that the roof or ground mount is structurally sound, that the racking system is designed for the local wind and snow loads, and that all necessary permits have been obtained. This allows any issues to be addressed before the racking installation begins, saving time and preventing potential safety hazards.

Inspection After Panel Installation

The second solar inspection typically occurs after the solar panels have been mounted to the racking system. During this stage, the inspector will verify that the solar panels are properly secured, that the electrical connections between panels and the racking system are correct, and that the system is designed and installed to meet the local electrical codes. This includes checking for proper wire sizing, securing, and labeling of electrical connections, and ensuring that the solar panel connectors are compatible with the inverter and electrical panel.

Final Inspection and System Testing

The final solar inspection and testing occur after the electrical connections have been made and the system is energized. The inspector will verify that the system is operating correctly, that the inverter is functioning properly, and that all safety interlocks and disconnects are functioning as intended. This stage typically includes a visual inspection of the system, testing the electrical connections with a multimeter, and verifying that the system is producing the expected amount of power.
