What does kWp mean?
As with any electrical device, the power of a PV solar energy system is measured in Watts. A kilowatt, or kW, is a thousand Watts. However, because the power generated by a PV system depends on light availability, ‘Standard Test Conditions’ (or STC) are defined under which the power is measured. The power of a PV solar energy system is normally quoted at STC and is measured in kWp (kilowatt power).
