19、r pumping systems. It also defines minimum actual performance values to be obtained on-site. It does riot address PV pumping systems with batteries. The parameters defining the photovoltaic power generating system (PVPGS) and the standard days, used to provide data in figure 1, should be in accordan
20、ce with IEC standards, in preparation, on the reference solar day. 2 Short term predlcted characteristlcs 2.1 The cuwes shown in figure 1 and figure 2 shall be given, and shall take Into account the following parameters: - Hi (kWh - m-2 . day“): mean daily in-plane total irradiation. See values 4, 6
21、, and 7 kWh - m-2 - day- given in figure 1 ; - Hb (kWh.m“* - day-): mean daily in-plane total irradiation during the reference period; Daiiy and instantaneous predicted de/V8ry curves - Gi (W - m-*): in-plane total irradiance. Values are given in figure 2 for 250 W - m-2, 500 W . m-2, 800 W - m-2, 1
22、 O00 W - m-2, and the higher value Git of Gi. for which the instantaneous delivery, qo, is equal to zero; - Gio (W - m-2): in-plane reference total irradiance; - Mmt, (m): total manometric head. Values are given in figures 1 and figure 2 for 0,75 Mmt, 1.15 Mmt, and 1.3 Mmt,; - Tamd (OC): on-site mea
