Electric Power Monitoring System on Solar Panels with the Application of Internet of Things (IoT)

Abstract

This study designs an Internet of Things (IoT)-based solar panel power monitoring system with automatic cooling using a water sprayer to maintain solar panel efficiency. The cooling system functions when the panel temperature exceeds 25C, resulting in an efficiency increase of up to 27% compared to panels without cooling. This monitoring system collects panel temperature, voltage, and current data using sensors and Arduino connected to the Blynk application, allowing real-time monitoring of panel performance. Testing for 7 days showed that the temperature of the cooled panel was around 28.02C with a power efficiency of 64.1%, while without cooling, the average temperature was 37.69C with an efficiency of 41.74%. These results indicate a significant increase in efficiency and stability of power output. This IoT system also makes it easy for users to monitor panel performance data remotely, which can be applied in various weather conditions.
