Sun Tracker Single Axis Mini Project

Project Title: Design and Implementation of a Single-Axis Sun Tracker for Enhanced Solar Panel Efficiency

Executive Summary:

This project presents the design and development of a single-axis sun tracker system to improve the energy output of a solar panel. Utilizing a light-dependent resistor (LDR) positioned on either the east or west side of the panel, the system constantly monitors the sun’s position and adjusts the panel’s orientation accordingly using a servo motor. This report details the project’s components, functionality, testing methods, and key results, demonstrating its effectiveness in increasing solar power generation.

Introduction:

• Motivation: Briefly explain the importance of solar energy, challenges in maximizing its capture, and how single-axis trackers address these issues.
• Project Objectives: Outline the specific goals of your project, such as increasing solar panel efficiency by a certain percentage or reducing energy losses due to misalignment.
