Abstract

The performance of solar panels is greatly affected by their operational temperature. An increase in temperature due to direct sunlight exposure can cause a decrease in the output power efficiency of the photovoltaic panel. One solution to overcome this problem is to implement a cooling system. This research aims to optimize the output power of polycrystalline type solar panels with a capacity of 20 WP through the application of an active cooling system Thermoelectric Cooler (TEC) with perforated aluminum plates as passive coolers. This research uses three panels, namely, solar panels without cooling, solar panels using passive cooling, namely perforated aluminum plates and solar panels using Thermoelectric Cooler cooling with the addition of perforated aluminum plates. Each configuration was tested under the same weather conditions, with data collection carried out for 14 consecutive days starting at 09.00 to 15.00 WIB. The measured parameters include solar radiation intensity (W/m²), panel surface temperature (°C), voltage (V), and current (A). The results showed that cooling had a significant effect on increasing the energy efficiency of the panels. Panels without a cooling system only produced an average efficiency of 7.29%. Panels with perforated aluminum plates recorded an average efficiency of 9.09%. Meanwhile, the panel with a combination of TEC cooling with the addition of perforated aluminum plates is able to achieve an average efficiency of 12.50%. From these results it can be concluded that the combination of active and passive cooling is able to effectively reduce the panel temperature and significantly increase the output power efficiency.
