Consider a single 435 W, SunPower (Model: E20/435) PV module (Sce Table below) used to charge a 84-V battery a. What duty cycle should be provided to a maximum power point, buck-boost converter to deliver 86-V to the battery when the module is working at standard test conditions (STC)? How many amps will it deliver to the battery under those conditions? b. If the ambient temperature were to warm up some without a change in solar irradiance, should the duty cycle be increased or decreased and why? C. Suppose ambient temperature is 30°c with 1-sun of insolation. Recalculate the amps delivered to the battery, compared to STC TABLE Examples of PV Module Performance Data Under Standard Test Conditions (1 kW/m², AM1.5, 25°C Cell Temperature) Manufacturer SunPower Yingli First Solar NanoSolar Sharp Model E20/435 YGE 245 FS Series 3 Utility 230 NS-F13565 Material c-Si me-Si CaTe CIGS a-si Panel efficiency 20.1% 15.6% 12.2% 11.6% 9.6% Rated power PMPP (W) 435 245 87.5 230 135 Rated voltage VMPP (V) 72.9 30.2 49.2 40.2 47 Rated current IMPP (A) 5.97 8.11 1.78 6 2.88 Open-circuit voltage Voc (V) 85.6 37.8 61 50.7 61.3 Short-circuit current Isc (A) 6.43 8.63 1.98 6.7 3.41 NOCT (°C) 45 46 45 47 45 Temp.
