The increasing demand for sustainable and eco-friendly energy sources has accelerated the development of hybrid renewable energy systems. This paper presents the design and implementation of a dual power generation system that integrates solar and wind energy to provide a reliable and continuous power supply. The proposed system utilizes an Arduino Uno as the central controller to manage power generation, battery charging, and load operation. A 12 V rechargeable battery is employed for energy storage, while a charging control circuit ensures safe and efficient power management from both energy sources. A light-dependent resistor (LDR) and servo motor are incorporated to enable solar tracking, allowing the solar panel to automatically align with the direction of maximum sunlight, thereby improving energy harvesting efficiency. A voltage sensor continuously monitors the system voltage to protect the battery and connected load. The generated energy is used to power a 40 W load, demonstrating the practical applicability of the system. The experimental results indicate that the hybrid solar-wind approach enhances power availability and system reliability compared to single-source renewable systems, making it suitable for small-scale and off-grid applications.
