System Components

Modules

Photovoltaic modules or panels are made of semiconductors that convert sunlight directly into electricity. PV modules provide a safe, reliable, maintenance- free and environmentally friendly source of power for a very long time.

Inverters

PV cells generate direct current (DC), but most common appliances require alternating current (AC). An inverter is used to convert low-voltage DC to higher voltage AC. As the core intelligence centre of a solar PV system, the inverter can convert the DC output from the array to AC power that can be synchronized with the local utility. This feature makes it possible to sell electricity directly back to the grid.

Balance of System Components

The remaining electrical and mechanical components of a PV system are known as the balance of system components (BOS). Mechanical components include fasteners, brackets, enclosures, racks, and other structural supports. Electrical components include conductors, cables, conduits, junction boxes, enclosures, connectors, and terminations needed to make circuit connections between modules, disconnects, inverters, meters, and other electrical systems and equipment.
