Abstract

This project aims to develop a dual-axis solar tracking system designed to maximize the efficiency of solar panels by continuously orienting them towards the sun. The proposed model, inspired by the sunflower’s ability to track the sun, will utilize dual-axis tracking to follow the sun’s movement both vertically and horizontally. This approach is expected to significantly increase the energy output of solar panels compared to fixed systems. The project will involve the design, simulation, fabrication, and testing of the tracking model to demonstrate its effectiveness and practicality.

 Introduction

Solar energy is one of the most promising renewable energy sources. However, the efficiency of solar panels is heavily dependent on their orientation relative to the sun. Fixed solar panels cannot capture the maximum possible sunlight throughout the day, leading to suboptimal energy generation. A dual-axis solar tracking system can address this issue by ensuring that solar panels are always aligned with the sun’s position, thereby maximizing the incident solar radiation and energy output. This project seeks to design a dual-axis tracking model that mimics the natural movement of a sunflower, enhancing the overall performance of solar energy systems.

Problem Statement

Fixed solar panels are limited in their ability to capture sunlight throughout the day due to the constant movement of the sun. This limitation results in lower energy generation efficiency. There is a need for an effective tracking system that can dynamically adjust the orientation of solar panels to follow the sun’s path, thus maximizing energy capture. Traditional single-axis trackers improve efficiency but still fall short of the potential energy gains offered by dual-axis tracking systems. The challenge is to design a cost-effective, reliable, and efficient dual-axis tracking model.

Aim

The primary aim of this project is to design, develop, and test a dual-axis solar tracking model inspired by the sunflower’s heliotropic movement. The system will aim to optimize the orientation of solar panels to maximize energy capture and improve overall efficiency.
