Photovoltaic, or PV, cells are the basic building blocks that make up a solar panel. These cells convert energy from the sun into direct current (DC) electricity.
A combiner connects multiple wires carrying the electrical current generated by individual solar panels together into a capacity wire, which then flows to an inverter.
The inverter transforms direct current into alternating current (AC) electricity. AC electricity is the type of electricity that powers your computers and refrigerators.
The solar system sends this electricity to power your home and a utility meter measures your consumption and any excess energy you produce.
