SOLAR

Duties

PV installers typically do the following:

• Plan PV system configurations based on customer needs and site conditions
• Measure, cut, and assemble the support structure for solar PV panels
• Install solar modules, panels, and support structures according to building codes and standards
• Connect PV panels to the electrical system
• Apply weather sealant to equipment being installed
• Activate and test PV systems
• Perform routine PV system maintenance

At the jobsite, PV installers verify the measurements and design of the structure on which the PV system is being set up. For PV systems on flat roofs, PV installers must first add a structure that allows the PV system to be mounted at an angle. PV installers set up new systems on support structures and place PV panels or PV shingles on top of them. Once the panels are in place, they sometimes connect the panels to electrical components. After the system is in place, PV installers must test the system and its components.

PV installers use a variety of handtools and power tools, including drills, wrenches, saws, and screwdrivers, to set up PV panels and connect them to frames, wires, and support structures.

Depending on the job and state laws, PV installers may connect the solar panels to the electrical grid, although electricians sometimes do this task. Once the panels are set up, workers check the electrical systems for proper wiring, polarity, and grounding, and they also perform maintenance as needed.
