Arduino-Based Solar Tracking System for Optimized Sunlight Alignment
Year: 2026
Type: conference-paper
Abstract: The biggest challenge and concern in the coming years is the idea of generating energy with less fossil fuel use. The idea of using solar energy as a fuel and the ability to convert the freely available energy we receive from the sun into usable energy is exciting and perhaps the top priority now, compared to other renewable energy sources. Although solar energy is the most common form of green energy, it faces some challenges. Fixed solar panels suffer from reduced energy production efficiency due to the changing angle of the sun throughout the day, leading to a decrease in wattage generated, especially on cloudy winter days. This research paper presents a solution using an Arduino-based single-axis solar tracking system. The system consists of an Arduino, low-latency photoresistors (LDRs), and servo motors to continuously adjust the angle of the solar panel. The experimental results show a significant increase in energy production, with an improvement of up to 48.19% in winter and 21.97% on sunny summer days compared to a fixed system. The solar tracking system proves effective in significantly increasing energy production and is an excellent alternative to fixed panels.
