A solar-powered air heating system using one ended evacuated tubes. A solar air heater containing evacuated tubes is used for heating purpose. With the increased attention the efficiency of solar heating facilities and the performance of additional equipment are becoming increasingly important. In the present study, thinking is giving on the heat transfer characteristics of solar air heater with some modifications in design to increase air travel length. Performance of solar air dryer would be checked with and without air heater. Effect of climate conditions would also be studied on its performance
