In the worldwide scenario, solar air heating system (SAHS) is mainly used for various applications. Renewable energy plays very important role in air heating system for industrial and domestic applications. Basically solar air heating system using Copper U-Tube Evacuated Solar Collector is useful for agricultural applications. In our experimentation, author primarily focuses on improving the thermal performance of solar air heating system. Experimental result shows that maximum output temperature of air achieved is 130–140 °C. This solution will be easily adoptable in agricultural as well as selected industrial applications.
