Performance of solar collectors for the DRY data sets

In the following figures solar thermal performance in units of [kWh/(m2 year)] is plotted as a function of the mean solar collector fluid temperature in units of [°C]. The results are shown for various irradiance and temperature DRY data sets relative to the previous DRY data set of Lund (1995), which is shown with black curves. The figures are made for three different areas in Denmark in pairs of two. The figures in each pair show the thermal performance of collectors without and with ETFE foil, respectively. All these figures are taken from the technical report by Dragsted & Furbo (2012).

Yearly thermal performance of a solar collector without an ETFE foil as a function of the mean solar collector fluid temperature for different Design Reference Years for Zealand and Bornholm.
Yearly thermal performance of a solar collector with an ETFE foil as a function of the mean solar collector fluid temperature for different Design Reference Years for Zealand and Bornholm.
