Efficient PV Monitoring with LoRaWAN: Integrating IoT and Smartphone Application for Cost-Effective Solutions

This paper presents a low-cost, scalable approach for monitoring photovoltaic (PV) installations, catering to the growing demand for effective monitoring frameworks in renewable energy. The system incorporates sensors to record critical data such as solar panel output, battery status, and ambient variables, addressing cost-effectiveness, scalability, and remote monitoring concerns in PV installations. Data transfer is supported via a LoRaWAN network, providing long-range and low-power connectivity, making it ideal for remote and off-grid PV systems. Field testing results show that the system provides real-time data on PV system performance, enabling preventive maintenance and informed decision-making. The inclusion of LoRaWAN technology improves system scalability and efficiency, providing a path for mass adoption in sustainable energy solutions. The low-cost design makes PV systems accessible to a wide range of users, including those in distant or economically challenged locations. The research describes a realistic and efficient monitoring approach customized to the unique requirements of PV systems, contributing to the greater adoption of sustainable energy solutions by using LoRaWan technology.
