PENGEMBANGAN MODUL SIMULASI PANEL SURYA BERBASIS LAMPU PIJAR SEBAGAI ALTERNATIF PRAKTIKUM ENERGI SURYA DI LABORATORIUM

Abstract

This research was conducted to address the challenges of conducting solar panel practicum in the Energy Engineering laboratory during cloudy or rainy weather by developing a simulation module for solar panel experiments using incandescent lamps as the light source. The testing and analysis revealed that solar panel efficiency is higher under sunlight (5.64% at 504 W/m²) compared to incandescent lamps (5.04% at 500 W/m²), with a more pronounced efficiency drop under lamp lighting due to rising temperatures. When temperatures exceed 40°C, a significant decline in efficiency occurs, with rates of 0.106/°C for the lamp and 0.093/°C for sunlight. The solar panel simulation module using incandescent lamps can serve as a practical solution for conducting experiments during overcast or rainy conditions.
