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:

1. Secure the adjustable support with

the base rail.

2. Secure the upper and lower adjusta-

ble supports in accordance with the

required angle of inclination (see

page 15).

Fitting the collector supports

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.

site substructure in accordance with

DIN 1055.

2. Clear the position for installation, for

example of gravel, lay out the protec-

tive mats and position foot supports A

and B in accordance with the dimen-

sions on page 19.

3. Secure the base rails (use as drilling

template) to the foot supports.
