Abstract

The increasing energy demand, along with the fossil fuel crisis and its environmental impacts, has driven the use of renewable energy sources such as solar energy. As a tropical country, Indonesia has high solar radiation potential throughout the year, which can be utilized for irrigation water pumping systems. This study aims to evaluate the efficiency of polycrystalline solar panels in a direct-coupled submersible water pump system at Sriwijaya University. The research employed a descriptive quantitative method with three repetitions of data collection conducted between February and May 2025, from 09:00 to 15:00 WIB. Observed parameters included solar radiation intensity (W/m²), maximum voltage (Vmax), maximum current (Imax), input power (Pinput), output power (Poutput), and water discharge (L/hour). Pinput was calculated by multiplying solar intensity with the panel area of 1.3668 m², while Poutput was obtained from Vmax × Imax. Results showed the lowest efficiency was 0.21% and the highest was 6.31%, with average daily efficiencies of 4.24% (first test), 4.26%(second test), and 1.92% (third test). The maximum water discharge recorded was 1,311.5 L/hour, and the minimum was zero during cloudy conditions. The highest power output of 68.3 W occurred at 14:00 WIB (Day 2), while the lowest, 14.9 W, was recorded in the morning of Day 3. Regression analysis showed a strong correlation between solar intensity and power output (R² ≈ 0.95), as well as between power output and water discharge (R² ≈ 0.92), indicating the system's high dependence on solar irradiance. The decline in efficiency during cloudy and afternoon periods highlights the need for optimal lighting. This study recommends extending the observation period and regularly calibrating measuring instruments to improve data accuracy and validity. Keywords : Direct coupled, Efficiency, Solar Panel, Solar Radiation, Water Pump.
