1. Remove the roof tiles and install the support rails
The solar panel system that is mounted inset in the roof re-
places the roof tiles and therefore requires more space. Count
on 50 cm extra on each side of the solar panels.
For the weight bearing capacity to be sufficient an additional
supportive batten must be installed 19 cm from the last batten.
A wider and thicker board or sheet can also be installed to
provide greater stability.
A sealing membrane underneath the inset panel is recommen-
ded, especially when the roof is such that the solar panel sys-
tem cannot easily be inspected from the inside.
The sealing membrane must cover at least 0,5 m outside both
the solar panel’s sides and upper side. At the bottom edge
the sealing membrane must overlap the bottom fixing plate
by at least 10 cm.
NOTE
The sealing membrane is extra important for low
pitch roofs and where the roofing felt under the
battens is poor.

2. Measure out and determine the location of the solar
panels
When you decide where the solar panel is to be located, the
left side piece must be positioned on the batten in such a way
that roof tiles cover it. Two lines must therefore be drawn.
Line (1) goes under the kink in the panel, line (2) goes 15 cm
to the right of the kink in the panel. Line (2) is in the same
place as the solar panel's left edge.
