Solar Pv — Quiz

Test your understanding of solar pv with 5 practice questions.

Practice Questions

Question 1

A PV module has a rated power of 350 W at STC and a temperature coefficient of power of −0.35 %/°C. If the module’s operating temperature is 45 °C, what is its approximate power output?

Question 2

A grid‐connected PV system has a DC rating of 50 kW$_{STC}$ and receives an annual reference irradiation H = 1300 kWh/kW$_{STC}$. If its measured annual AC energy output is 52 000 kWh, what is its performance ratio (PR)?

Question 3

Estimate the expected annual AC energy yield of a PV installation with module area A = 100 m^2, module efficiency η = 18 %, annual plane‐of‐array irradiation G = 1500 kWh/m^2, and system PR = 0.75.

Question 4

For an off‐grid PV system that must supply an average daily load of 8 kWh, with 4 days of autonomy, system voltage of 48 V, and a maximum depth of discharge (DOD) of 60 %, what minimum battery capacity in ampere‐hours (Ah) is required?

Question 5

In a solar PV module’s I‐V characteristic, how does an increase in series resistance $R_s$ primarily affect the curve?
