ENperformance ratio 
(Symbol: RP) (Unit: dimensionless, usually expressed as a percentage, %)

index that shows the effect of PV system losses on the rated PV array capacity

NOTE 1 Typically, PV system losses are due to PV array temperature, incomplete utilisation of the irradiation and PV system component inefficiencies or failures

NOTE 2 The performance ratio is commonly calculated from the ratio of the final system yield over the reference yield
