W=2 Y=5 Z=0 Question 1 (a) A rooftop project in China selected a 140W solar module under conditions of 1-sun insolation, at ambient temperature of 30°C. The module has a nominal operating cell condition (NOCT) of 46.Y °C. It is given from the datasheet that at standard temperature of 25°C, Voc is 42.Z Volts, and Voc drops by 0.37%/°C. On the other hand, maximum power is expected to drop by 0.45%/°C. Analyse the given solar system as follows: i. Cell temperature, Tcell (3 Marks) ii. Open-circuit voltage, Voc (3 Marks) iii. Maximum power output, P max (3 Marks) iv. Estimate and explain the percentage drop of maximum power from rated power (2 Marks)
