where it was observed
from Fig. 5 that operating the cooling system for
5 min results in a decrease in the solar cells temperature by
10 C and an increase in the solar cell efficiency by 12.5%.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.
