Abstract: An increase in solar module temperature significantly reduces its electrical energy conversion efficiency. This study aims to analyze the effectiveness of a water sprayer-based cooling system in maintaining optimal module surface temperature and improving power efficiency. The system was designed using an ESP32 microcontroller and an STC1000 sensor to monitor temperature, current, voltage, and water flow rate. The water pump is automatically activated........
