Solar photovoltaic installer responsibilities are to install module array interconnect wiring, implementing measures to disable arrays during installation; install required labels on solar system components and hardware; install photovoltaic (pv) systems in accordance with codes and standards using drawings, schematics, and instructions; apply weather sealing to array, building, or support mechanisms;

assemble solar modules, panels, or support structures, as specified; visually inspect and test photovoltaic (pv) modules or systems; activate photovoltaic (pv) systems to verify system functionality and conformity to performance expectations; check electrical installation for proper wiring, polarity, grounding, or integrity of terminations;

identify methods for laying out, orienting, and mounting modules or arrays to ensure efficient installation, electrical configuration, or system maintenance; identify and resolve any deficiencies in photovoltaic (pv) system installation or materials; test operating voltages to ensure operation within acceptable limits for power conditioning equipment, such as inverters and controllers; identify installation locations with proper orientation, area, solar access, or structural integrity for photovoltaic (pv) arrays; demonstrate system functionality and performance, including start-up, shut-down, normal operation, and emergency or bypass operations; perform routine photovoltaic (pv) system maintenance on modules, arrays, batteries, power conditioning equipment, safety systems, structural systems, weather sealing, or balance of systems equipment; identify electrical, environmental, and safety hazards associated with photovoltaic (pv) installations; measure and analyze system performance and operating parameters to assess operating condition of systems or equipment; determine connection interfaces for additional subpanels or for connecting photovoltaic (pv) systems with utility services or other power generation sources; program, adjust, or configure inverters and controls for desired set points and operating modes; determine appropriate sizes, ratings, and locations for all system overcurrent devices, disconnect devices, grounding equipment, and surge suppression equipment; examine designs to determine current requirements for all parts of the photovoltaic (pv) system electrical circuit;

compile or maintain records of system operation, performance, and maintenance; install active solar systems, including solar collectors, concentrators, pumps, or fans; determine photovoltaic (pv) system designs or configurations based on factors such as customer needs, expectations, and site conditions; determine materials, equipment, and installation sequences necessary to maximize installation efficiency; diagram layouts and locations for photovoltaic (pv) arrays and equipment, including existing building or site features; select mechanical designs, installation equipment, or installation plans that conform to environmental, architectural, structural, site, and code requirements.
