the solar absorber plate 20 this significantly increases the heat transfer conductance between the solar absorber plate 20 and the ambient air which prevents the solar absorber plate 20 from overheating the air may or may not circulate in cavity 30 that depend upon the temperature difference across the cavity 30 and the cube of its gap distance 30 the temperatures of the solar absorber plate 20 and the inner glazing film 26 are not necessarily equal to the temperature of the cavity 30 whose temperature varies across the gap 30 from the temperature of 26 to the temperature of 18 once the circulation of the fluid through the heat collector 22 commences the temperature in the solar collector system 10 will lower and the inner glazing film 26 move away from the solar absorber plate 20 and becomes taut thereby returning the solar collector system 10 to its normal operation experiments with the solar collector system 10 of the present invention have revealed that when the experimentally measured solar absorber plate 20 stagnation temperature was approximately one hundred and sixteen 116 u00b0 c degrees celsius the outer glazing temperature was approximately fifty 50 u00b0 c degrees celsius if the inner glazing film 26 were not properly engineered so that it had remained taut the.
