Monitoramento da taxa de desempenho de módulo fotovoltaico através de microcontrolador e tecnologia Lorawan

Abstract

Like any electronic device, photovoltaic modules are susceptible to degradation. This project aims to develop a prototype capable of monitoring the performance rate of these modules, enabling the user to analyze its current state and take necessary actions if they show below-expected performance. The project was developed using various low-cost sensors available in the national market. The selected sensors can measure humidity, pressure, ambient temperature, surface temperature, irradiance level, dust concentration, and GPS coordinates. These data are processed by a microcontroller and transmitted to an internal server using LoRaWAN technology. This is a long-distance data communication technology suitable for applications in remote locations where easy internet access is unavailable, as is the case with photovoltaic module installations. Lastly, the data is made available to the user through dashboards accessible via any device with access to the Internet. Although the development of a prototype could not be completed, promising data was still collected, even in its incomplete state.
