2.1 Prior to installation

Prior to installation of solar collectors, select a suitable 
position respecting the following conditions:

•  roof facing South
•  roof inclination (25°- 45°)
•  unshaded place 
•  accessible for servicing
•  permissible roof load
•  shortest possible distance between the collectors and 

(accumulation) tank

Further have ready the necessary material, tools and 
safety equipment for working on a roof.
Check if the roo

fi

 ng manufacturer offers roof hooks and 

if the roof warranty will not be violated. 

2.1.1 Installation with roof anchors and au-
xiliary boards

Prior to installing anchors on auxiliary boards, the fo-
llowing shall be ensured: 
•  The auxiliary board length shall exceed the length of 

the rail by at least 200 mm on each end.  

•  The auxiliary board width shall be between 100 and 

200 mm.

•  It shall be 30 mm thick.
•  The height of the auxiliary board from the counter 

batten shall be equal to the batten thickness which 
can be reached by underlying the auxiliary board (see 

Fig. 3

).

Installation

•  Remove roo

fi

 ng so that auxiliary boards can be 

inserted (approx. distance between boards 1600-1800 
mm). For roof tiles, just shifting them upwards  in the 
length of the auxiliary board is suf

fi

 cient (see 

Fig. 4

).

•  Fit the auxiliary boards to battens so that the distribu-

tion of anchors resembles the positions in Fig. 2. At 
the same time screw the boards so high that the roof 

anchor does not hinder placing the roof tile with the 
right overlap (see Fig. 8).

•  Hang the roof anchors onto the auxiliary board 

respecting their distribution shown in Fig. 2.  

•  Fit the anchors using stainless steel screws.

2.1.2 Installation with roof anchors for rafters

For tiled roofs, rafter anchors can be used. Either a 

fi

 xed 

(not adjustable) stainless-steel hook (Fig.7a) can be 
used, or an adjustable aluminum anchor (Fig. 7b) that 
enables horizontal shift of the anchor along the fastening
