Solar Photovoltaic Installers

Typical tasks

From O*NET 31.0. Core tasks first. Few of these tasks have a benchmark today.

• Install photovoltaic (PV) systems in accordance with codes and standards, using drawings, schematics, and instructions.
• Check electrical installation for proper wiring, polarity, grounding, or integrity of terminations.
• Identify electrical, environmental, and safety hazards associated with photovoltaic (PV) installations.
• Identify installation locations with proper orientation, area, solar access, or structural integrity for photovoltaic (PV) arrays.
• Assemble solar modules, panels, or support structures, as specified.
• Apply weather sealing to array, building, or support mechanisms.
• Install module array interconnect wiring, implementing measures to disable arrays during installation.
• Install required labels on solar system components and hardware.
• Diagram layouts and locations for photovoltaic (PV) arrays and equipment, including existing building or site features.
• Determine materials, equipment, and installation sequences necessary to maximize installation efficiency.
• Test operating voltages to ensure operation within acceptable limits for power conditioning equipment, such as inverters and controllers.
• Determine appropriate sizes, ratings, and locations for all system overcurrent devices, disconnect devices, grounding equipment, and surge suppression equipment.
