Photovoltaics (PV) is a method of generating 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.
Photovoltaic panels convert the sunlight directly into electricity. A typical example of a device powered by photovoltaic cells is a solar powered calculator.
This type of device only needs a small amount of electrical power to work and can even be used in a room with artificial light (bulbs / fluorescent light). Solar photovoltaics have long been accepted to be a sustainable energy source.
More than 100 countries use solar PV. Installations may be ground-mounted (and sometimes integrated with tillage and grassland systems) or built into the roof or walls of a building (either building-integrated photovoltaics or simply rooftop).
The electricity generated by your solar power system is free, clean, sustainable and reliable. It will help reduce the amount of greenhouse gases – a major contributor to global climate change.
