The irradiation values measured on location yields an average solar irradiation for the entire analysis period of 120 kWh/m².
This irradiation value is extrapolated to the modular area of the PV plant as follows:
Irradiation value in kWh/m² x plant area in m² = 120 kWh/m² x 10 m² = 1,200 kWh
In order to subsequently calculate the nominal plant output, the irradiation value for the PV plant is multiplied by the modular efficiency:
1,200 kWh x 15 % = 1,200 kWh x 0.15 = 180 kWh
PR = 110 kWh/180 kWh = 0.61112 = 61.11 %
