Original abstract
Conventional fixed photovoltaic (PV) panels lose significant output because the sun's position changes continuously and dust accumulates on the panel surface. This paper presents an enhanced PV system combining dual-axis solar tracking with a cleaning alert system and IoT real-time monitoring. Four LDR sensors and an ESP32 drive two DC motors through an L298N H-bridge to align the panel along the azimuth and elevation axes. A dual-channel alert, using INA219 power sensors and an ESP32-CAM, detects dust-related loss. Results show a ≈42% improvement in daily energy yield over a fixed installation, ±2° tracking accuracy, and a dust-alert response under five minutes.
