Daily PR: Photovoltaic Daily Full Load Hours / Daily Irradiation
CPR = (Actual Production + Sum of all external losses) / Theoretical Production
PR Calculation Logic
Both monthly and annual PR values are ‘recalculated after aggregation’; they are not calculated as the average of daily PR values.
Cumulative electricity generation for the period = PR × installed capacity × cumulative irradiance for the period
Monthly PR: Monthly cumulative electricity generation ÷ installed capacity ÷ monthly cumulative irradiance
Annual PR: Annual cumulative electricity generation ÷ installed capacity ÷ annual cumulative irradiance
