A Real-Time Monitoring Device for Assessing Photovoltaic Performance in Residential Settings

This project introduces an add-on device that monitors key data points essential for evaluating the daily performance of a photovoltaic (PV) array. It is designed for homeowners who are transitioning to solar energy for economic or environmental benefits. The goal is to enhance the operational understanding for users by offering a smart system capable of detecting inefficiencies, especially for users with limited technical knowledge of PV components. The device measures five parameters: light intensity, temperature, humidity, current, and voltage. These metrics have been successfully integrated and are fully operational. This paper details the electronic design, hardware prototype, and data collected to validate the system’s performance.
