ANALYSIS OF SOLAR POWER GENERATION TECHNOLOGY FOR ELECTRIC VEHICLE CHARGING

Abstract

In the era of energy transition and the increasing demand for electric vehicles, the availability of efficient, sustainable, and environmentally friendly energy sources has become a major challenge. This study aims to analyze the performance of a Solar Power Generation System (PLTS) as a charging solution for electric vehicles by evaluating the effect of panel tilt angle variations on the generated energy. The research employed an experimental approach with three tilt angle variations 5°, 10°, and 15° on an off-grid solar power system without a solar tracker. The system consists of four 250 Wp monocrystalline solar panels mounted on a 3-meter pole in a solar tree configuration. Testing was conducted at Universitas Negeri Surabaya using a lux meter, DC Digital Electric Meter, and multifunction digital meter. Quantitative data analysis was applied to determine system efficiency and energy output. The results show that a tilt angle of 10° yielded the highest efficiency of 6.2% and an average energy output of 40.4 Wh per hour, followed by 5° with 5.44% (39.6 Wh) and 15° with 5.33% (36.35 Wh). Simulation of charging a Viar EV1 electric vehicle demonstrated that the system could fully charge one unit from 40% to 100%, and continue charging a second unit up to 61%, 59%, and 52% for tilt angles of 10°, 5°, and 15°, respectively. These results indicate that the panel tilt angle significantly affects the efficiency and effectiveness of a static solar power system in charging electric vehicles in tropical regions.
