How does water immersion affect PV panels?

PV panel surface temperature increases, and the PV panel’s efficiency decreases due to thermal conduction. Water immersion is one way of cooling PV panels, but the proper depth of immersion is required to trade off the solar radiation and PV efficiency. More immersion depth leads to the loss of incoming radiation and transmissivity losses.

Can a solar cooling system solve the problem of overheating PV panels?

Therefore, it is concluded that the proposed cooling system could solve the problem of overheating the PV panels due to excessive solar radiation and maintain the efficiency of the panels at an acceptable level by the least possible amount of water.
