Below you will find the 15min PR calculation formulas


Raw PR (site level)


Raw PR=(Exported Power Site/ Nominal Power DC)/(Irradiance PoA Average/1000)


AL-corrected PR (site level)


AL-PR=Raw PR/Availability


Raw PR (inverter level)



Raw PR=(Power Inverter AC/ Nominal Power DC)/(Irradiance PoA Average/1000)
