Adjusting The Angle Of Inclination Α - Viessmann VITOSOL 300-T Installation Instructions Manual

Installation on flat roofs
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 °

Adjusting the angle of inclination α
Position the collector array as far south as possible; linear tube axis aligned east-
west.
