If a surface is exposed to solar radiation, it will be heated. In this sense, any such exposed surface is a solar collector. The degree of this heating will depend on (1) the amount of radiation incident on the surface and (2) the absorptance of the surface. Radiation incident on a surface can be measured as. 1.Solar Expansion Tank - VesselsThe diaphragm of solar tanks ensure that the solar system pressure do not go beyond of drop way below the needed within the system design.
