A photovoltaic (PV) module is installed in a location at latitude 40 N. The PV module is tilted towards the south and the tilt angle is the latitude of the location, i.e., =40. (a) On the 21st of March (equinox day) at solar noon for that location: Indicate the sun altitude (B) and azimuth angle (,). If the direct beam insolation at ground level la is 950 W/m, calculate the direct beam insolation on the PV module (IBC). . - - - If the diffuse factor C is 0.082, calculate the diffuse radiation on the PV module (IDC). (9 Marks) (b) The PV module I-V characteristic under the operating conditions of part (a) is shown in Figure 1 on Page 3. Estimate the power supplied by the PV module in the following cases: If the reflectance coefficient on the ground p is 0.1, calculate the reflected radiation on the PV module (IRC). The load is a battery having a voltage VB of 25 V. - The load is a resistance R of 5 Ohms. There is a DC-DC converter between the PV module and the load that is operated with maximum power point tracking. Note: Draw Figure 1 in the answer booklet and indicate the operating points corresponding to the conditions above graphically.
