When the front facing surface of PV solar panels are exposed to sufficient levels of sunlight, i.e. solar radiation, a DC electric current is produced. For PV grid-connected power systems, this
DC solar generated current is fed into an inverter and converts it to AC current. The AC current then powers AC loads connected directly to the PV system, while any surplus AC power is exported
onto the main electricity grid.
What does PV mean?
PV is an abbreviation of the word photovoltaics (photo=light, voltaics=electricity) and refers to semi conductor-based technology that is used to convert light energy directly
into electricity. There are no moving parts, no consumption of fuel, and is pollution free.
