Gautam Mohan Posted March 23, 2023 Share Posted March 23, 2023 Why Global Incident Radiation(Glob Inc) is used in PR calculation in PVSyst instead of Global Effective Radiation (Glob Eff)? Link to comment Share on other sites More sharing options...
Agnes Bridel Posted March 24, 2023 Share Posted March 24, 2023 The performance ratio is the ratio of energy produced and energy used if the system were to continuously work at STC condition, as defined in the norm IEC EN 61724. Barring normalization factors, this is equivalent to the ratio of energy produced in given conditions versus the available energy on the PV plane (for a grid-connected system). The latter is GlobInc and not GlobEff. See the help page "Project Design > Results > performace Ratio" for more information. Best regards, Link to comment Share on other sites More sharing options...
