Researchers are striving to improve the efficiency of photovoltaic panels. As
efficiency of PV cells decrease with temperature rise, panel cooling would increase
the power output and solar energy can be better exploited. One of the strategies for
this purpose is passive cooling by use of fins. In the present study, annual energy
output of a 50W panel is calculated in two unfinned and pin-finned cases based on
meteorological data of Shiraz, Iran. The results show that with the installation of 2
cm, 4 cm and 6 cm aluminum pin fins with finned-to-total-backside-area ratios of
0.17, 0.27 and, 0.55 the power output increases by 1.24-4.16%, compared to the
unfinned case. This increase is equivalent to 1.04-3.50 kWh, more energy
production during a year.
