3. Information / Pipework examples
Ideally, the collectors should be oriented between south-east and south-west
(optimum: south). Please refer to our technical advisors in case of an alternative
orientation. Trees, neighbouring structures, chimneys, etc. should throw as
little shade over the collectors as possible. Observe the different position of
the sun (summer/winter).
The clearance between the top edge of the solar collectors and the bottom
edge of the gable should be at least three tiles deep to enable the flow line to
be rising inside the attic space.
In areas subject to heavy snow loads ensure that the snow can slide off the
collector. In other words, roof structures below the collector surface must be
avoided. For safety reasons, never damage cross battens or the tile under the
roof hooks (cracked, drilled, aged), otherwise they might break under extreme
snow loads. If in doubt, replace battens and / or tiles in these areas.
It would also be advantageous, when mounting the solar collectors on top of
the roof, if the tiles below the roof hooks were to be replaced by lead tiles.
Observe the snow load in accordance with EN 1991, 2-3 and DIN 1055-5.
Notes
Pipework examples
A collector array consists of up to 10 collectors, when connecting pipework on
alternate sides.

the highest point)

Recommendation:
Piping several collector arrays in
accordance with Tichelmann
