Smart Solar Tracking and Cleaning System

Overview

This solar panel tracking and cleaning system enhances power harvesting by optimizing solar panel exposure and maintenance. The tracker system adjusts the panel according to the Sun's position to maximize solar light collection using a solar irradiation sensor. The cleaning system maintains a clean panel surface with a wiper and water sprinkler. An MCU controls the tracking and wiper motors and operates the water pump solenoid valve. Wi-Fi, Bluetooth® Low Energy (LE), and LTE modules provide cloud connectivity and enable remote operation, enhancing system functionality and accessibility.

System Benefits:

  • Low maintenance requirement due to the use of BLDC motors.
  • Ultra-low power Wi-Fi + Bluetooth LE module enables cloud connectivity and integration with smart home systems.
