The collector is operated at constant temperature θm (mean of in- and outlet temperatures). The calculation of the annual
collector performance is performed with the official Solar Keymark spreadsheet tool Scenocalc Ver. 5.01 (March 2016). A detailed
description of the calculations is available at www.solarkeymark.org/scenocalc

%
Remark: Collector efficiency (η
col
) is defined in CDR (EU) No
811/2013 as collector efficiency of the solar collector at a
temperature difference between the solar collector and the
surrounding air of 40 K and a global solar irradiance of 1000
W/m2, expressed in % and rounded to the nearest integer.
Deviating from the regulation η
col
is based on reference area
(A
sol
) which is aperture area for values according to EN 12975-2
or gross area for ISO 9806:2013.

Remark: The data given in this section are related to collector
reference area (A
sol
) which is aperture area for values according
to EN 12975-2 or gross area for ISO 9806. Consistent data sets for
either aperture or gross area can be used in calculations like in the
regulation 811 and 812 and simulation programs.
