The Effect of Fins Number Variation on Aluminum Heat Sink to the Photovoltaic Performance

摘要

Optimization of energy becomes a popular topic nowadays due to the rise in global energy demand, the decrease in fossil fuel, and environmental problems. One of the solutions to cope with those problems is solar energy. Solar energy has a problem, which is the increased working temperature of the panel. Working temperature increase in panel photovoltaic (PV) panels will cause a decrease in performance and damage to PV panels. One way to reduce the working temperature in PV panel is a cooling method using a heat sink. The variations used were no fin, 5 fins, and 10 fins. This study to obtain the I-V curve obtained by measuring the voltage and current values. Panel without heat sink (ground) was obtained efficiency of 8.72%, maximum power of 34.18 W, and working temperature of 72.6°C with the same intensity 1100 W/m~2. Heat sink panel no fins obtained an efficiency of 9.13%, maximum power of 39.65 W, and working temperature of 69°C. Heat sink panel with 5 fins, the efficiency is 9.58%, the maximum power is 39.65 W, and the working temperature is 66.5°C. Heat sink panel with 10 fins, the efficiency is 10.21%, the maximum power is 40.17 W, and the working temperature is 63.4°C. The results showed that the number of fins the efficiency increased from 0.56 to 1.8%, increased the maximum power by 2.56-5.55 W, and the working temperature decreased by 3.6 to 9.1°C compared to the panel without heat sink.
