Abstract
The sun provides an abundant energy source, harnessed by solar photovoltaic (PV) cells to produce electricity. However, conventional PV cells have low conversion efficiency, as their output fluctuates due to varying light intensity and the sun's shifting position in the sky. This variability reduces the efficiency of stationary solar panels at different times of the day and throughout the year. Solar panels perform best when aligned perpendicularly to the sun, but efficiency decreases when the orientation changes. To improve this, sun tracking systems boost efficiency and energy output by following the sun's daily and seasonal movement from east to west. This research introduces a cost-effective two-axis active solar tracking system, utilizing a light-dependent resistor to detect the sun's position and an Arduino Uno microcontroller to control two linear actuators, ensuring the panels stay aligned perpendicularly to the sun for maximum power generation.
