Installation on collector supports

Prevent shading if several collectors are installed
behind each other. Maintain clearance z between
rows.
1. Determine the angle
(the shortest day of the year) at midday.
In Germany, this angle measures between 11.5°
(Flensburg) and 19.5° (Konstanz), subject to lati-
tude.
Example:
Würzburg is approximately located on latitude 50°
north. In the northern hemisphere, this value is
deducted from a fixed angle of 66.5°:
= 66.5° 50° = 16.5°
