Performance Comparison of 10Wp and 15Wp Monocrystalline Solar Panels on 12V Battery Charging

Abstract

The increasing demand for electrical energy has encouraged the utilization of renewable energy sources, particularly solar energy through photovoltaic technology. The charging time of a 12 V battery is influenced by the power capacity of the solar panel used. This study aims to compare the charging time of a 12 V battery using 10 Wp and 15 Wp monocrystalline solar panels. The research employed a quantitative experimental method with a comparative approach. Both panels were tested under identical environmental conditions using the same charging system. Data were collected through direct measurements of output voltage, current, power, efficiency, and battery charging duration during the testing period. The results indicate that the 15 Wp monocrystalline solar panel produced higher output current and power than the 10 Wp panel, resulting in a shorter battery charging time. In contrast, the 10 Wp panel required a longer charging duration due to its lower power output. These findings demonstrate that panel capacity significantly affects charging performance. Therefore, the 15 Wp monocrystalline solar panel is recommended for small-scale 12 V battery charging applications because it provides faster charging and higher energy conversion performance
