Abstract: The depletion of fuel sources leads to energy crisis is serious and burning issue. The alternative energy is always better option and out of available resources like solar energy, wind energy and biomass; but compare to wind energy and bio mass solar energy is always better option because solar energy is the easiest source to extract useful energy in terms of availability in ample amount. The objective of present work is to develop spiral solar air heater and performance will be check using K type thermocouple.
