Determining the collector row distance z
When installing several collectors in series, maintain distance z (see page 19).
Example:
Würzburg is located at approx. latitude 50° north.

1. Determine the angle of the sun β.
In Germany, this angle (subject to lat-
itude) lies between 12 ° (Flensburg)
and 20 ° (Freiburg).
Angle of the sun:
90 ° − 23.5 ° − latitude
(23.5° can be assumed as a constant
value)
90 ° − 23.5°− 50 ° = 16.5 °
2. Calculating dimension z:
h = 2165 mm
α = 45 °
β = 16.5 °

Information regarding ballast and
max. load on the substructure
Calculation in accordance with
DIN 1055-4 8/1986 and DIN 1055-5
6/1975.
Two foot supports A and two foot sup-
ports B are required for each collector
(see the following diagram).
For the calculation, the Viessmann cal-
culation program "SOLSTAT" is availa-
ble at www.viessmann.com.
