Photovoltaic Systems
Photovoltaic (PV) systems use photovoltaic cells to capture energy from sunlight and convert it into direct current (DC) electricity. This electricity can then be used as DC (often stored in a battery) or converted into alternating current (AC) via an inverter. A PV module or ‘panel’ is formed from a number of cells which are connected within the module into sub-strings. Modules are normally connected together into one or more strings to form what is known as an array.
