temperatures of 29.6 C, 45.1 C, and 50.5 C. The I–V test was measured
during the cooling of the stationary solar module at mentioned
temperatures under solar intensity of I = 1100 W/m2. The
output power of the stationary solar PV system was presented versus
the voltage in Fig. 8a. From the figure, it is evident that the
higher the PV temperature, the less energy will be produced.
Similar performance can also be seen in the voltage versus temperature
graph of Fig. 8b. It is obvious that the voltage is highly dependent
on the temperature and an increase in temperature will
decrease the voltage at constant current.
