Some of the key things solar inspectors look for during the inspection process are:
Roof structure and attachments: They will check that the roof can structurally support the panel weight and that mountings are properly secured.
Electrical connections: They confirm all wiring is up to code, properly sized, and adequately protected.
Voltage and currents: They test that voltage and currents are within expected ranges throughout the system.
Safety features: They check that all required safety mechanisms like shut off switches are installed and functional.
Panel condition: They inspect panels for any damage sustained during installation.
Inverter operation: They ensure the inverter is working properly to convert the solar energy into usable electricity.
Meter connection: They confirm the meter is correctly allowing energy to flow both ways.
Waterproofing: They check areas where roof or walls were penetrated to confirm proper seals.
The goal is to verify all solar components were installed correctly and safely.
