Abstract

The efficiency of solar panels is generally influenced by the installation tilt angle, as it affects the amount of sunlight absorbed and the detector's response in converting light intensity into electrical energy. This study aims to analyze the relationship between light intensity, efficiency, and photocurrent responsivity of monocrystalline solar panels based on experimental data collected in Bengkulu City. The research method employed correlation and linear regression analysis to evaluate the relationships between light intensity, efficiency, and photocurrent responsivity at tilt angles of 0°, 30°, and 60°. The results indicate that the highest efficiency of 15% was achieved at a 0° tilt, even though the highest light intensity of 146,467 lux occurred at a 60° tilt. The relationship between light intensity and efficiency is nonlinear, although a positive correlation was observed, with the highest regression coefficient of 0.0000006x and the highest coefficient of determination (R²) of 39.19% found at a 30° tilt. Conversely, the relationship between light intensity and photocurrent responsivity exhibited a negative correlation, with the highest regression coefficient of –0.0000001x and the highest R² of 25.98% at a 60° tilt. These findings suggest that the linear relationship between light intensity and both efficiency and photocurrent responsivity is relatively weak, likely due to other dominant factors affecting the performance of the solar panel
