5.9.5.
Differing mounting rail intervals in rows/columns
The interval of the mounting rails for a particular module row
or column can be different for each module row or column.
This allows for a certain degree of freedom with respect to the
intervals of the mounting rail pairs.
This applies particularly to asymmetrical clamping and, in
certain cases, also to symmetrical clamping.
5.9.6.
Identical mounting rail intervals in rows/columns
If the installation situation requires identical intervals for the
mounting rails in all module rows or columns, e.g. due to
aesthetic requirements, the requirements for symmetrical
clamping areas for very high loads, or bolt installations, aleo
solar recommends a dual-layer substructure.
This makes it possible to align the top layer of profiles
independently, for example, from the tile rows.
The free space under the modules is also thereby increased,
often by more than 45 mm. This means:
at high pressure loads, there is a greater degree of
freedom regarding clamping and less additional
effort required (e.g. omission of additional clamps
or supports),
the modules are better ventilated from the back
and are cooler, which may bring yield advantages.
5.9.7.
Bolt installation
aleo modules have mounting holes with a diameter of 9 mm.
This makes it possible to also attach the modules with M8
(5/16 inch) size bolts (see Ch. 9.4, 'Mounting with bolts'). A
bolt installation requires an appropriate interval between
mounting rails. Avoid flush fitting in a bolt installation
situation. This is an option (see also Ch. 7.4.1, 'Spacing
between the module frames'), but aleo solar recommends
mounting at intervals.
5.9.8.
Lay-in installation
Avoid flush fitting. This is an option (see also Ch. 7.4.1,
'Spacing between the module frames') but, aleo solar
recommends mounting at intervals.
On-roof installation
Modules can be lined up on both the long and
the short side.
In-roof installation
Line up the modules exclusively on the long
side.
Free-field installation
Modules can be lined up on both the long and
the short side.
Also, please observe the guidelines provided by the mounting
system manufacturer.
5.10.
Anti-theft protection
The following list contains a number of anti-theft options (it is
not exhaustive):
Fill the internal hexagon of the bolt heads with cast
resin.
Use bolts with a head that separates with a defined
torque during installation.
Use specially shaped cross slot bolts that can be
screwed in, but not out.
Engrave a self-explanatory code in the frame, e.g.
the
O
wner
I
dentification
N
umber (acronym: 'OIN')
which is made up of five components: city or area
code from the vehicle number plate, municipality
key, street name, house number, and the initials of
the operator.
Use a substructure with locking technology that
requires special tools for removal.
Put a fence around an free-field system.
Install CCTV.
Install an electronic monitoring system.
NOTICE
Avoid driving steel balls into the bolt head internal
hexagons. The strong vibration can cause micro-
cracks and yield losses, and lead to a loss of
warranty.
Also avoid boring the internal hexagons of the bolts.
The vibration can also cause micro-cracks and yield
losses, and lead to a loss of warranty.
Avoid driving in (stamping) identification marks in
the frame. The strong vibration can cause micro-
cracks and yield losses, and lead to a loss of
warranty.
Avoid engraving identification marks into the
module glass. This could irreparably damage the
module.
