A Review of Experimental study of Solar Air Heater with different Parameter

Solar energy is an inexhaustible resource. The sun produces vast amounts of renewable solar energy that can be collected and converted into heat and electricity. In the application of solar energy to the heating of dwellings and other uses, the primary element in the heating system is the ‘‘Collector’’. Most collectors employed a black-painted, flat absorber plate with heat-transfer passages built within, above or below it and with one or more glass covers on the top. The heat transfer in solar collector takes place by simultaneous radiation, convection, and conduction.
