Abstract
The global shift towards renewable energy sources necessitates efficient monitoring solutions for solar photovoltaic (PV) systems to maximize their performance and sustainability. Traditional monitoring systems often involve high costs and complex setups, posing barriers to widespread adoption, particularly for small-scale installations and research projects. In response to these challenges, this paper proposes a novel, low-cost energy monitoring solution tailored for solar PV systems. The system integrates off-the-shelf components, including a Power Supply Hi-Link 5V, an Espressif EP32-WROOM microcontroller, an RS485 to Serial Converter, and an energy meter, offering a cost-effective alternative to conventional monitoring systems. By connecting to the output of the solar PV inverter, our solution captures real-time energy production data, which is seamlessly transmitted to a controller and stored in the cloud-based platform ThingSpeak for remote monitoring and analysis.Keywords
