Solar PV( photovoltaic) system, is a power system designed to supply usable solar power by means of photovoltaics. It consists of an arrangement of several components, including solar panels to absorb and convert sunlight into electricity, a solar inverter to convert the output from direct to alternating current, as well as mounting, cabling, and other electrical accessories to set up a working system.
First solar cell capable of converting enough of the sun’s energy into power to run every day electrical equipment was discovered in 1950’s , with efficiency of 4%. Since then the technology has developed in many ways and solar PV was used in many applications from powering up calculator’s to supplying electricity to such advanced technologies as international spaceships. Finally, it became a widespread source of energy for many ordinary people like you and me ranging from residential and commercial rooftops Solar PV installations (1kW to hundreds of kW) to big scale commercial power stations (Megawatts) supplying electricity to our homes through utility companies.
