Photovoltaic (PV) systemis a method ofgenerating electrical power by converting solar radiation into direct current electricity using semiconductors that exhibit the photovoltaic effect. Photovoltaic power generation employs solar panels composed of a number of solar cells containing a photovoltaic material. Due to the increased demand for renewable energy sources, the demand on solar photovoltaic systems has increased considerably in recent years.
Solar cells produce direct current electricity from sun light which can be used to power equipment or torecharge a battery through a charge controller. The first practical application of photovoltaics was to power orbiting satellites and other spacecraft, but today the majority of photovoltaic modules are used for grid connected power generation. In this case an inverter is required to convert the DC to AC.
Renewable power can be suitable for many applications such as:
- – Residential apartments
- – Buildings
- – Power stations
- – Transport
- – Street / Garden lighting
- – Telecommunication
