Solar glass absorption rate

Does absorption of solar radiation in glass cover increase heat flow?

Thermal network for upward heat flow in single and double glazed flat plate solar collectors including the effect of absorption of solar radiation in glass cover (s). Absorption of solar radiation in the glass cover has been analyzed as a case of uniform heat generation. The rate of heat generation per unit volume is ( αg I / Lg ).

Does solar absorption increase glass cover temperature?

It is found by analysis that due to absorption of solar radiation in glass cover of a single glazed flat plate collector the increase in glass cover temperature under certain conditions could be as high as 6°.

How is absorbed solar radiation distributed in glazing systems?

In the numerical solutions of the distribution of absorbed solar radiation in various glazing systems presented here, each thick element in a glazing layer was divided into a fixed number of ‘slices’, and the radiation absorbed at coated interfaces was added to the amount of radiation absorbed in the adjacent ‘slice’.

What is solar absorption rate?

For thorough understanding, the absorption rate can be formulated as the ratio of the energy absorbed by the surface to the total solar energy incident on that surface, generally leading to a mathematical expression that can be tailored according to the specific scenario at hand.
