PV panel has 72 series connected identical silicon PV cells divided to three modules of 24 PV cells which are protected by bypass diodes. The panel has a short circuit current of 12 A, an open circuit voltage of 43.2 V and Fill Factor of 0.80 in standard test conditions (STC). a) Plot the current and power of one PV cell in the panel as a function of voltage in STC conditions. (2 points) b) Plot the current and power of one PV module in the panel as a function of voltage under nominal operating condition when NOCT = 50 C, irradiance is 800 W/m, wind speed is 1 m/s, solar radiation spectrum is AM1.5 and Kv=-0.15 V/K. (3 points) c) Plot all possible currents as a function of voltage on the PV panel when the panel is operating under STC conditions, except that three PV cells are shaded, one receiving irradiance of 800 W/m and the other two receiving irradiance of 200 W/m.
