IoT-based intelligent solar panel protection system with automatic rain and heat protection control

Abstract

An IoT-based intelligent solar panel protection system with automatic rain and heat dissipation control, comprising: a solar panel array for generating electrical energy from solar radiation; a power supply unit with a rechargeable battery and voltage regulator to supply the system components with regulated voltage; an environmental sensor unit with at least one rain sensor for precipitation detection, at least one temperature sensor for monitoring the temperature of the solar panel array, at least one light intensity sensor for detecting the direction and intensity of incident sunlight, and optionally one or more humidity and voltage sensors for monitoring environmental and electrical operating parameters; a microcontroller connected to the environmental sensor unit that continuously receives and processes sensor data.compares the received sensor data with predefined thresholds and generates control signals based on the processed sensor data; a solar tracking mechanism connected to the microcontroller that automatically aligns the solar array with the direction of maximum sunlight based on signals received from the light intensity sensor; a protective mechanism positioned next to the solar array that is movable between an open position, exposing the solar array, and a closed position, covering the solar array; a motor driver connected to the microcontroller; at least one servo motor coupled to the protective mechanism and configured to receive control commands from the microcontroller via the motor driver to move the protective mechanism between the open and closed positions; and an IoT communication module.which is configured for wireless communication with a remote cloud platform and a user device for the transmission, storage, monitoring, and analysis of operational and environmental data, wherein the microcontroller is configured to keep the protective mechanism in the open position during normal operation to allow maximum solar energy generation, automatically actuates the servo motor to move the protective mechanism to the closed position when continuous rain is detected for a predetermined period or when the temperature of the solar module assembly exceeds a predetermined threshold, thereby protecting the solar module assembly from moisture-related damage and thermal deterioration, and is further configured to automatically return the protective mechanism to the open position after the rain stops and the temperature drops below the predetermined threshold.
