Pengaruh Nano Fluida sebagai Material Sistem Pendingin terhadap Efisiensi Panel Surya

Abstract

The amount of energy required is increasing as the economy and population grow. The increasing amount of energy used, the less the supply of conventional energy reserves, the decreasing amount of fossil energy results in the need for renewable energy, to prevent the imbalance between economic progress and conventional energy reserves. The development of alternative energy around the world has increased. One of them is solar energy, solar panels are a semiconductor element that can convert solar energy into electrical energy with photovoltaic principles. The PLTS system will work optimally under standard conditions, namely the intensity of sunlight has a value of 1,000 W/m2 with a solar module temperature value of 25°C, and the solar radiation spectrum is in a global position, where the angle of incidence of sunlight is 0°. In this study, the authors used CuO-Water nanofluid as a solar panel surface cooling material. The results showed that the use of CuO-Water nanofluid cooling produced an average solar panel output power of about 26.10 Watts and could reduce the surface temperature of solar panels by about 19.21°C with a solar panel efficiency of about 13.26%, while the use of water cooling produced an average solar panel output power of about 25.14 Watts and could reduce the surface temperature of solar panels by about 12.32°C with a solar panel efficiency of about 12.48%.
