Perbandingan output daya modul panel surya monocrystalline dan polycrystalline 50 wp berdasarkan iradiasi dan suhu yang berbeda

This study aims to evaluate and compare the performance of monocrystalline and polycrystalline solar panels through direct field testing under varying lighting, irradiation, and temperature conditions. The testing was conducted by adjusting different load resistor values and recording solar irradiation, panel surface temperature, output voltage, and current every hour from 11:00 AM to 3:00 PM. The collected data were used to calculate the actual output power, energy conversion efficiency, and performance ratio (PR) of each panel.
Based on the measurements, the average solar irradiation in June 2025 was 4.160 kWh/m²/day, or approximately 832 W/m², which is below the standard maximum of 1000 W/m². High panel surface temperatures were proven to reduce power output. The average energy conversion efficiency was 5.95% for the monocrystalline panel and 3.19% for the polycrystalline panel. Meanwhile, the performance ratio (PR) was 0.4111 for monocrystalline and 0.220 for polycrystalline.
In conclusion, the monocrystalline panel demonstrated better and more consistent performance than the polycrystalline panel, especially under high irradiation and fluctuating temperature conditions. Therefore, monocrystalline panels are more suitable for solar power applications in tropical regions with high sunlight intensity.
