Solar energy is a highly potential renewable energy source, especially in tropical regions that receive abundant sunlight throughout the year. This study aims to evaluate the performance of a 100 Wp monocrystalline solar panel under clear and cloudy weather conditions to determine the impact of weather changes on electrical energy conversion efficiency. Data were collected over three consecutive days by measuring light intensity using a BH1750 sensor, while voltage and current were recorded through an Arduino Uno–based monitoring system. The results indicate that solar panel performance is optimal during clear weather, whereas efficiency decreases by up to 44.4% under cloudy conditions due to reduced light intensity. These findings highlight the importance of technical strategies, such as energy storage systems and the use of panels adaptive to diffuse radiation, to improve solar energy performance in tropical regions. Additionally, integrating local weather monitoring can support more efficient and responsive energy management.
