Data Acquisition and Monitoring for Photovoltaic Plants Based on Low-Cost IoT Technologies

With the significant increase in the installed capacity of photovoltaic plants, especially large plants, challenges related to monitoring generation are becoming increasingly common, mainly due to the high cost of equipment, leaving small companies and even end consumers without a monitoring. For effective management of energy generation, it is important to remotely monitor operational information, daily production and climatic variables that influence generation. However, this task becomes expensive for facilities located in remote areas where physical access is limited. In this context, this project's technological contribution is the development of a monitoring system and a data acquisition prototype capable of sending it to the internet and accessing it from anywhere using simple programming language, such as the Arduino IDE and the board ESP32 development.
