Title

Dual Axis solar tracking system

Abstract

With fossil fuels like oil and gas becoming scarce, there's a growing need for alternative energy sources. Solar energy is a promising option, thanks to the sun's virtually limitless supply of power. However, to make solar energy more commercially viable, we need to improve its efficiency in capturing sunlight. This project focuses on designing a system that tracks the sun's movement and directs sunlight towards solar panels. By doing this, the panels will receive a more consistent and intense source of sunlight, boosting their electricity output. Developing this system requires further research to improve existing solar tracking technology. This project utilizes Light Dependent Resistors (LDRs) to detect sunlight, a DC gear motor for movement, and an ESP8266 microcontroller as the central processing unit. The microcontroller acts as the brain of the system, receiving sensor data, processing it, and controlling the motor to track the sun. Programming knowledge is crucial, as the program uploaded to the microcontroller dictates the system's operation. The project focuses on building a working model to test the sun-tracking mechanism. This prototype uses a geared DC motor mounted on a base made of Perspex to move the solar panel throughout the day, simulating sunrise to sunset. Tests are being conducted to refine the design and ensure the system operates efficiently and reliably.
