Sistem Monitoring Daya Keluaran PLTS terhadap Penurunan Suhu Permukaan Panel Surya

The output power monitoring system of a photovoltaic (PV) power plant was developed to analyze the effect of surface temperature control on solar panel performance. The study utilized a 50 Wp monocrystalline solar panel. An experimental method was employed by comparing panel performance under two operating conditions: without a cooling system and with a water-cooling system. The system was integrated with a real-time monitoring platform capable of measuring panel surface temperature, voltage, current, and output power continuously. Testing was conducted from 09:00 to 13:00 WIB. The novelty of this study lies in the integration of a water-cooling system with a real-time monitoring system for a 50 Wp PV module to directly evaluate the relationship between panel surface temperature and output power. The results indicate that the implementation of the cooling system increased the output power from 16.95 W to 29.70 W at 10:00, from 32.64 W to 35.88 W at 11:00, and from 36.72 W to 38.64 W at 13:00. In addition, the panel surface temperature remained more stable within the range of 29.3–35.6°C. The monitoring system successfully provided accurate and continuous measurements throughout the testing period. These findings demonstrate that reducing the panel surface temperature can effectively enhance output power and improve the operational stability of the PV system
