Photovoltaic system

A photovoltaic system (PV system or solar electric system) is designed to capture and harness the sun's energy using photovoltaics. A PV system consists of several components: solar panels that capture sunlight and convert it into electricity, an inverter that transforms the output from DC to AC, and other mounting components, cables, and electrical accessories that are needed to create a functional system. It may also include a tracking system for the sun to increase overall performance, and integrated battery solutions, given the expected drop in prices of storage devices. As photovoltaic systems convert light directly into electricity, they should not be confused with other solar technologies, such as concentrated solar power or solar thermal energy, which are used for heating and cooling.

The system can also include advanced technologies such as tracking systems - smart meters or battery solutions, which are increasingly popular as they allow excess energy to be stored for later use, which is particularly useful during periods when solar energy production is lower or in the event of a power grid failure.
