Analisis Perbandingan Performa Modul Surya Polycrystalline dan Monocrystalline Berkapasitas 320 Wp Menggunakan Perangkat Uji Sun Simulator PASAN

Electric current, measured in amperes (A), and potential difference, measured in volts (V), are the two main forms of electrical energy needed to run electrical devices. The energy required to start, run, or maintain mechanical and electronic devices, such as motors and lighting fixtures, is represented by the electrical power consumption, which is measured in watts (W). The Sun Simulator Pasan test system is used in this study to evaluate the performance of monocrystalline and polycrystalline solar modules. A flash from a light box is focused onto the solar modules during the testing process under controlled circumstances, such as an air mass spectrum of AM1.5, an ambient temperature of 25°C, and an irradiation intensity of 1000 W/m². The Photovoltaic Module Quality Testing Laboratory (LPKMF), BRIN-PUSPIPTEK, examined both monocrystalline and polycrystalline modules with a 320 Wp rating in accordance with laboratory standards.  Comparing the efficiency and performance variations of the two varieties of solar modules with comparable rated capacities is the aim of the test conducted under Standard Test Conditions (STC).  According to the findings, the Polycrystalline module achieved an efficiency of 17.79% with a peak power output of 315.722 Wp, which deviates 9.278 Wp, or around 2.03%, from its rated value.  In the meantime, the monocrystalline module attained an efficiency of 18.82% and produced a peak output of 323.838 Wp, which was 1.602 Wp or 2.79% higher than the rated 325.44 Wp. These findings demonstrate that Monocrystalline modules exhibit slightly higher performance and efficiency under identical testing conditions.
