Uji variasi Cairan sebagai Pendingin dalam Meningkatkan Efisiensi Solar Panel

Abstract

The increase in solar panel surface temperature during the energy conversion process is one of the main factors contributing to the decrease in photovoltaic system efficiency, especially in tropical regions with high solar radiation intensity such as Indonesia. This study aims to test and compare the effectiveness of several types of liquid coolants in reducing the surface temperature of solar panels and increasing their electrical energy conversion efficiency. The method used is an experimental approach by applying three types of coolants—water, Velux water coolant, and Motorrad water coolant—on a monocrystalline solar panel cooling system. Observed parameters include panel surface temperature, voltage, current, and power output. The results showed that the use of liquid coolants significantly reduced panel temperature compared to the condition without any cooling, with performance varying based on the type of coolant. Motorrad water coolant demonstrated the best performance in stabilizing temperature and enhancing energy output. These findings indicate that selecting the appropriate type of coolant has the potential to increase the energy output of solar panel systems, making it a practical solution for improving renewable energy efficiency in hot climate regions. This study is expected to contribute to the development of more efficient and sustainable solar energy technology.
