Abstract

This research utilizes solar energy to generate electricity through solar panels with experimental study methods in outdoor (sunlight) and indoor (lights) conditions. Experiments using two 500-watt (12000 Lux) incandescent lamps produced a maximum power of 5.25 watts at 35°C with an intensity of 94.8 W/m², while sunlight produced up to 13.93 watts of power at 55°C with an intensity of 206.6 W/m² using a 20 Wp polycrystalline panel. The power increases to the optimum temperature, then decreases due to thermal effects. Low temperature improves efficiency; high temperature lowers it. A 21.6 Ah (12 V) lithium-ion battery stores 259.2 Wh of energy, and with the slow charging method, it takes about 2 hours to reach the 20% discharge limit. Indoor testing with light lamps provides a more stable alternative. The increase in light intensity increases power to a certain point before decreasing due to temperature.
