Solar Powered Homes

Photovoltaic (PV) arrays are by far the most common form of residential solar installation. These systems collect photons from the sun and convert the energy they contain into useful solar electricity.

The fundamental unit of a PV array is a solar cell, composed primarily of a semiconductor material, where the conversion of light to electricity takes place. As the output of these cells is relatively small they are packaged together into larger units called modules (or panels), which in turn are combined to form PV arrays. Apart from the PV modules, there are a number of “balance of system” components required for the array to function – including inverters, mounting or racking equipment, disconnect switches, combiner boxes, and wires and connectors.
