| Popis: | 31st European Photovoltaic Solar Energy Conference and Exhibition; 2408-2411 Many modern PV modules have a much higher fill factor than the P-V curves used in standard test procedures for PV inverters. A high fill factor makes a PV module more susceptible to MPP tracking losses. Single phase grid connected PV inverters without DC link always have a ripple on the DC side. This ripple makes an ideal MPP tracking impossible, because even if the DC voltage is optimized, the operating point always oscillates around the MPP. A high fill factor increases the losses caused by this effect. This paper shows that these losses can be as high as or even exceed the losses caused by the inverter’s conversion efficiency. This is done by data obtained with a simulation model, but also with actual measurements performed on a real PV inverter. |
