Green Occupation:
47-2231.00 - Solar Photovoltaic Installers

Green occupations will likely change as a result of the green economy. Green economy activities and technologies are increasing the demand for occupations, shaping the work and worker requirements needed for occupational performance, or generating new and emerging occupations.

This is a Green New & Emerging occupation — the impact of green economy activities and technologies is sufficient to create the need for unique work and worker requirements, which results in the generation of new occupations.

Solar photovoltaic installers work in the following green economy sectors:

  • Renewable Energy Generation — This sector covers activities related to developing and using energy sources such as solar, wind, geothermal, and biomass. This sector also includes traditional, non-renewable sources of energy undergoing significant green technological changes (e.g., oil, coal, gas, and nuclear).

They perform these tasks important to the green economy:

  • Activate photovoltaic (PV) systems to verify system functionality and conformity to performance expectations.
  • Apply weather sealing to array, building, or support mechanisms.
  • Assemble solar modules, panels, or support structures, as specified.
  • Check electrical installation for proper wiring, polarity, grounding, or integrity of terminations.
  • Compile or maintain records of system operation, performance, and maintenance.
  • Demonstrate system functionality and performance, including start-up, shut-down, normal operation, and emergency or bypass operations.
  • Determine appropriate sizes, ratings, and locations for all system overcurrent devices, disconnect devices, grounding equipment, and surge suppression equipment.
  • Determine connection interfaces for additional subpanels or for connecting photovoltaic (PV) systems with utility services or other power generation sources.
  • Determine materials, equipment, and installation sequences necessary to maximize installation efficiency.
  • Determine photovoltaic (PV) system designs or configurations based on factors such as customer needs, expectations, and site conditions.
  • Diagram layouts and locations for photovoltaic (PV) arrays and equipment, including existing building or site features.
  • Examine designs to determine current requirements for all parts of the photovoltaic (PV) system electrical circuit.
  • Identify and resolve any deficiencies in photovoltaic (PV) system installation or materials.
  • 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.
  • Identify methods for laying out, orienting, and mounting modules or arrays to ensure efficient installation, electrical configuration, or system maintenance.
  • Install active solar systems, including solar collectors, concentrators, pumps, or fans.
  • Install module array interconnect wiring, implementing measures to disable arrays during installation.
  • Install photovoltaic (PV) systems in accordance with codes and standards using drawings, schematics, and instructions.
  • Install required labels on solar system components and hardware.
  • Measure and analyze system performance and operating parameters to assess operating condition of systems or equipment.
  • Perform routine photovoltaic (PV) system maintenance on modules, arrays, batteries, power conditioning equipment, safety systems, structural systems, weather sealing, or balance of systems equipment.
  • Program, adjust, or configure inverters and controls for desired set points and operating modes.
  • Select mechanical designs, installation equipment, or installation plans that conform to environmental, architectural, structural, site, and code requirements.
  • Test operating voltages to ensure operation within acceptable limits for power conditioning equipment, such as inverters and controllers.
  • Visually inspect and test photovoltaic (PV) modules or systems.
