Solar Photovoltaic Installers

Solar Photovoltaic Installers typically perform the following tasks: • 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. • Activate photovoltaic (PV) systems to verify system functionality and conformity to performance expectations. • Identify and resolve any deficiencies in photovoltaic (PV) system installation or materials. • Visually inspect and test photovoltaic (PV) modules or systems. • Examine designs to determine current requirements for all parts of the photovoltaic (PV) system electrical circuit. • Demonstrate system functionality and performance, including start-up, shut-down, normal operation, and emergency or bypass operations. • Identify methods for laying out, orienting, and mounting modules or arrays to ensure efficient installation, electrical configuration, or system maintenance. • Measure and analyze system performance and operating parameters to assess operating condition of systems or equipment. • Program, adjust, or configure inverters and controls for desired set points and operating modes.
