+# Smart Solar Panel Sytem
+The Smart Solar Panel Management System optimizes solar energy efficiency using a tracking mechanism, self-cleaning system, and ultrasonic sensors to deter animals. Powered by ESP32, it enables real-time monitoring of voltage, temperature, and current via a mobile app. This IoT-driven solution enhances energy output, reduces manual maintenance, and ensures sustainable, cost-effective solar power management.
