Abstract

A popular alternative to using fossil fuels to generate power is to use a photovoltaic (PV) system. However, the efficiency of PV system is very sensitive to the environmental conditions and frequent maintenance is needed to achieve the best performance. In practice, data of both the surrounding environment and the PV system need to be collected simultaneously to monitor the status and also to characterize the performance of the system. But this cannot be done manually as the PV system is commonly placed at remote or hard-to-reach places. To address this problem, an IoT based solar photovoltaic monitoring system is designed and developed in this project. ESP32 is used as the core processing unit. Several sensors such as temperature, solar irradiation, current and voltage sensors are used for data collection. An IoT cloud server is used to store and display the data. The measurement results show satisfactory accuracy and reliability of the system. Further data analysis of the collected high temporal resolution sensor data reveals substantially different correlations of the parameters in three different weather conditions during non-rainy days, namely cool and cloudy, moderately hot and sunny, and very hot and sunny. A support vector machine (SVM) regression is proposed to predict the PV panel temperature and the result is compared to the conventional least square regression. Improved prediction performance is observed especially for the very hot and sunny scenario.
