Install photovoltaic (PV) systems in accordance with codes and standards, using drawings, schematics, and instructions.

Assemble solar modules, panels, or support structures, as specified.

Apply weather sealing to array, building, or support mechanisms.

Determine appropriate sizes, ratings, and locations for all system overcurrent devices, disconnect devices, grounding equipment, and surge suppression equipment.

Install module array interconnect wiring, implementing measures to disable arrays during installation.

Identify methods for laying out, orienting, and mounting modules or arrays to ensure efficient installation, electrical configuration, or system maintenance.

Identify electrical, environmental, and safety hazards associated with photovoltaic (PV) installations.

Examine designs to determine current requirements for all parts of the photovoltaic (PV) system electrical circuit.

Check electrical installation for proper wiring, polarity, grounding, or integrity of terminations.

Test operating voltages to ensure operation within acceptable limits for power conditioning equipment, such as inverters and controllers.
