In this paper, a solar panel cooling system was implemented to know the effect of temperature on the variables (output) of the solar cell in terms of electrical power, voltage and current, as well as the effect of flow level and cooling time, as I used two identical solar panels. The first panel was cooled and the second panel was not cooled for comparison. The effect of cooling on the capacity was about 8.6%, while the effect of cooling on the voltage was around 6.45%, and these values were at the times of peak solar radiation at midday for the city of Misurata during the month of August 2019 AD and also the rate of temperature drop was good about 20% and these values were affected Greatly on the efficiency and performance of the solar panel.
