Photovoltaic output changes with irradiance, panel temperature, shading, orientation, and electrical loading. This paper presents an ESP32-based platform that measures voltage, current, temperature, and light intensity from a 12 V solar panel and transfers time-stamped records to a personal computer through USB serial communication. A Python pipeline validates and stores the measurements, computes power and energy, creates leakage-safe time-series features, and compares several regression algorithms for short-horizon energy prediction. A Flask dashboard integrates live monitoring, historical plots, data-quality warnings, model metrics, and forecasts. The proposed evaluation uses chronological splits, fixed preprocessing, and common metrics so that persistence, linear, tree, ensemble, and kernel models can be compared fairly. The work emphasizes calibrated measurement and traceable validation because prediction quality cannot be separated from sensor accuracy and dataset integrity.
KEYWORDS
This paper presented an AI-assisted renewable-energy performance monitoring architecture based on a 12 V solar panel, calibrated sensors, an ESP32, USB serial communication, Python analytics, and a Flask dashboard. The design measures electrical and environmental conditions, preserves raw and calibrated records, and computes power and energy only from time-aligned valid samples. The predictive workflow compares persistence, linear, tree, ensemble, and kernel regression methods using fixed features, chronological folds, and common metrics. The evaluation intentionally separates model development from the final test period and records all configuration needed for reproduction. Experimental accuracy will be reported only after hardware calibration and representative data collection are complete. Future work can extend the acquisition period across seasons, add calibrated irradiance and weather inputs, estimate forecast intervals, detect model drift, and evaluate transfer between panels. These additions should retain the same traceability principles so that changes in hardware, data, and models remain distinguishable.
