Calculation of the collector mounting distance to avoid shading
Flat roof example:
Example of pitched roof:
In order to avoid shading throughout the year, the lowest sun position of the year should be specified.2)
Since the angle of solar radiation in the transition period is between 20° and 40°, a collector tilt angle of approx. 60° is best for heating support.3)
If the collector is mounted on a pitched roof, the existing roof pitch must also be specified.
