The role of a solar collector cover is to maximise the solar radiation collected whilst retaining the heat generated. One way the cover does the latter is by containing a layer of warm air so that a lower rate of convective heat loss to ambient takes place from the cooler outside surface of the glazing than would from the much hotter absorber.
