IoT-based experimental prototype for monitoring of photovoltaic arrays

In this paper a smart prototype has been designed for monitoring of PV arrays using Internet of Things (IoT). An electronic sensing board has been designed. A website application has been also developed in order to monitor the data online (electrical PV array current and voltage, air temperature and solar irradiance). The designed prototype has been verified experimentally at Renewable Energy Laboratory in Jijel University (Algeria). Experimental results showed the capability of the prototype to monitor the data without using additional circuits and efforts. The prototype could be used for fault detection (FD) in PV arrays by integrating for example a FD algorithm.
