If the pump is operated such that it sprays water over the PV panels at a flow rate of 29 l/min, this will result in cooling of the PV panels from the MAT of 45 °C to 35 °C in 4.7 min. In this case, it can be concluded that the cooling rate of the PV panels is ∼2.0 °C/min, and the water spraying should be stopped after 4.7 min. Figure 3.
