How it works: PV systems use cells, modules, and arrays to capture sunlight and convert it into electrical energy. PV systems are modular in nature, meaning that basic building blocks of smaller components and subsystems are integrated to construct larger systems. Individual cells are combined to make modules. Modules are then combined to achieve the desired system voltage and power output, forming an array.

The basic physical process of a PV system converts light into electricity known as the photovoltaic effect. The photovoltaic effect is the movement of electrons within a material when it absorbs photons with energy above a certain level. Photons of light transfer their energy to electrons in the material surface. The electrons with enough energy to escape from their atoms are conducted as an electrical current.

An inverter is a device that converts the DC (Direct Current) power from the PV array into AC (Alternating Current) that can be used to power your building.
