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

aperture area for values according to EN 12975-2 or gross area for

ISO 9806:2013.

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.
