Analysis of Photovoltaic Current Based on Tilt Angle Variation Using the ANOVA Method

Abstract

Solar panels play a crucial role as the main component in a Solar Power Plant (PLTS), where solar energy is converted into electrical energy. The efficiency of power conversion in solar panels is influenced by various factors, including material type, tilt angle, and weather conditions. To optimize efficiency, proper adjustment of the panel's tilt angle is required to achieve maximum current output. The variation in tilt angles remains a challenge in obtaining high efficiency, necessitating a method to address this issue effectively. The use of ANOVA aims to analyze the effect of solar panel tilt angle variations on output current, providing a reference for PLTS installation. This study was conducted through experimental research on solar panels by applying various tilt angles to collect current distribution data. The data was then processed using sufficiency tests, normality tests, homogeneity tests, and ANOVA. The findings indicate that tilt angle variation significantly affects output current, as the ANOVA test result yielded a P-value of 0.0405, indicating statistical significance. Furthermore, the experiment identified an optimal tilt angle for maximizing current output, with a recommended angle of 20° facing eastward.
