PV installers typically do the following:

• Plan PV system configuration based on customer needs and site conditions
• Install solar modules, panels, or support structures in accordance with building codes and standards
• Connect PV panels to the power grid
• Apply weather sealing to equipment being installed 
• Activate and test PV systems to verify performance
• Perform routine PV system maintenance

Sunlight is considered an environmentally friendly source of energy. By way of photovoltaic panels, sunlight is transformed into electricity. Recent technological advances have sufficiently reduced the cost of solar panels to make it a viable source of electricity for businesses and homeowners alike. PV installers put these systems in place.

PV installers use a variety of hand and power tools to install photovoltaic panels. They often use wrenches, saws, and screwdrivers to connect panels to frames, wires, and support structures.

Many new workers begin by performing basic tasks, such as installing support structures and placing PV panels or PV shingles on top of them. Once the panels are in place, more experienced installers usually perform more complex duties, such as connecting electrical components.

Depending on the job and state laws, PV installers may connect the solar arrays to the electric grid, although electricians sometimes perform this duty. Once installed, workers check electrical systems for proper wiring, polarity, grounding, and integrity of terminations, and perform maintenance as needed.
