This manuscript presents the design and implementation of a web-based automatic solar panel monitoring system using the ESP8266 microcontroller. The system enables real-time monitoring of solar panel performance, including voltage, current, and power output, accessible remotely via a web interface. The proposed approach emphasizes practicality, cost-effectiveness, and ease of deployment for small- to medium-scale solar installations. All experimental setups, datasets, and implementation details are included in the manuscript. This submission has not been published elsewhere and is intended for consideration as an original research article.
