Peak capacity of solar cells refers to the amount of power generated by the solar cells under the best possible solar radiation. Peak capacity of solar cells denoted in Watt-peak (Wp), Kilowatt peak (kWp) or MW peak (MWp), refers to the maximum power the solar cells can deliver under standard conditions’ typically referring to conditions of good sunlight. A 1 kWp solar cell can generate power at 1 kW if the DNI -Direct Normal Irraidance (a measure of sunlight) is good.
