Calculation in accordance with DIN 1055-4, 3/2005 and DIN 1055-5,
7/2005.
Two foot support slabs each A and B are required respectively for each
collector.
Determining the collector row clearance z
At sunrise and sunset (when the sun is very low), shading cannot be
avoided when collectors are arranged behind one another. To keep
the reduction in yield within acceptable parameters, observe specific
row clearances (dimension z) in accordance with VDI
Directive 6002-1. When the sun is at its highest on the shortest day of
the year (21.12.), the rows at the back should be free of shading.
The angle of the sun β (at midday) on 21.12. must be used to calculate
the row clearance.

Note
For the calculation, the Viessmann "SOLSTAT" calculation program is
available at "www.viessmann.com".
In Germany, this angle (dependent upon latitude) is between 11.5°
(Flensburg) and 19.5º (Konstanz).
