General installation guidelines
General
– Durning installation of the solar mounting system, the instructions and
safety precautions presented in this document and the accompanying
installation manual must be followed carefully. As also stated in the General
terms and Conditions of sale and delivery of Van der Valk Solar Systems B.V.,
non-compliance with the installation guidelines in this document means that
the customer can no longer invoke any warranty and Van der Valk is no longer
liable for any form of damage.
– The information, comments and advice in this document are binding. Van der
Valk Solar Systems reserves the right to update this document without further
notice.
Safety
– The installation of the mounting system must be carried out by qualified
technical personnel.
– Omitting parts may negatively affect performance and is therefore not
allowed.
– Avoid carrying out installation work during bad weather conditions,
especially in case of strong winds and a wet (slippery) roof surface.
– During the planning and execution of the installation, always take into
account possible changing weather conditions, in particular strong winds or
storms. Take the right measures and make sure that no situation can arise
where solar panels have already been placed on the system, but other essential
parts (such as ballast tiles, side or back plates) are still missing.
– During installation work on the roof, always use fall protection and, if
necessary, work with safety nets and roof edge protection.
– Always wear appropniate protective clothing and gloves when carrying out the
installation work.
– Follow the guidelines in the publication “health & safety in roof work’.
Environmental factors
– High neighbouring buildings or objects, such as windmills, can affect the
wind pressure. In these cases, advice should always be obtained from Van der
Valk Solar Systems before instalation can take place.
– If prior to, during or after the installation it 1s determined that the
project data and/or environmental factors do not fully correspond to the
project report, the project must always be re-calculated and any required
adjustments need to be made.
– Incoastal areas, the system should be placed at least 500 meters from open
water to prevent accelerated corrosion by the action of salt water. When
buildings are present between the open water and the roof, a minimum distance
of 250 meters from open water may be maintained.
Standards and regulations
For correct and safe installation and use of the solar mounting system, always
observe the applicable standards and regulations:
– EN 1990: Basis of structural design
– EN 1991-1-3: General actions: snow loads
– EN 1991-1-4: General actions: wind loads
– IEC 60364: Electrical Installations for Buildings

Stability and condition of the roof and roof covering
– Placing a mounting system that uses ballast only, is only allowed in case
the roof pitch is less than 5°. In case the roof pitch 1s 5° or more the
mounting system always needs to be fixed mechanically to the roof.
– The condition of the roof must be checked upfront for sufficient strength to
bear the weight of the mounting system including PV panels ballast and wind
and snow loads. Make sure that the load reserve of the roof is not exceeded
anywhere.
– Check the stability of the roof and adjust the roof/construction where
necessary.
– Check prior to installation whether the roof covering and/or insulation 1s
suitable for the pressure and thermal expansion of the solar mounting system.
The maximum pressure 1s shown in the project report of the ValkPVplanner or
can be requested at Van der Valk Solar Systems.
– Bulging of the roof membrane should be prevented. This can hifit the solar
mounting system and can cause displacement of the mounting system or ballast.
Itis the installer’s responsibility to prevent the roof membrane from bulging.
– Factors such as overhead cranes, seismic activity and others that affect the
stability of the roof and/or building can affect the installed solar mounting
system. Van der Valk Solar Systems does not take these factors into account,
unless confirmed in writing.
– The roof surface on which the solar mounting system is to be installed must
be clean, dry and flat.
– The roof height may not exceed 25 meters in case the project has been
calculated in the ValkPVplanner must be corresponding to the roof height in
the project report. For installations on roofs higher than 25 meters, Van der
Valk Solar Systems should always be contacted in advance.
Roof zones
– When installing the solar mounting system, always take the applicable
roof zones according to EN1991-1-4 into account. Placing solar panels in the
edge zone of the roof (the distance measured from the roof edge, which is
equal to 1/5 of the building height) is only possible if this has been
explicitly taken into account in the calculation.
– [tis possible to position panels in the edge zone of the roof in the
ValkPVplanner (calculation software), on the basis of which the required
additional ballast or fixation points are automatically calculated. This can
only be done using “Satellite” or “White Map’ design mode. The edge zone Is
automatically calculated by the ValkPVplanner, based on the roof height and
building circumference, in accordance with the applicable regulations. In case
the design mode “Simple mode’ is used, the calculation always assumes that the
solar panels are in the middle zone of the roof only.
– Incase solar panels on the ValkPro+ system are fully or partially placed in
the edge zone of the roof, it is mandatory to use side plates.
– ValkKits (ValkBox3, ValkDouble, ValkTriple, ValkQuattro) can only be placed
in the middle zone of the roof. Placing these systems in the edge zone of the
roof is not allowed.
Ballast
– After installation of the solar mounting system, it must be carefully
checked whether the ballast has been placed in accordance with the ballast
drawing. Ballast tiles must be neatly stacked, so that they are sufficiently
supported by the tile carriers, mass corners and/or ballast wings.
Dilatations
– The maximum allowed dimensions of a coupled mounting system is a 30
meters in the aluminium direction and 60 meters in the steel direction. The
maximum dimensions are based on the thermal expansion in case of a maximum
temperature difference (Delta T) of 70 degrees Celsius.
– The coupled mounting system must not be placed over a gutter or ridge. In
the mounting system is place over a gutter or ndge, the system must be split
(dilatation), even if the change in roof pitch is minimal.
– When using the extra wide panel support feet for ValkPro+ with ballast,
different dilatation rules apply: in such installations the coupled system may
be a maximum of 30 meters in the steel/roof carrier direction and 15 meters in
the aluminium direction.
Solar panels
– Itis the responsibility of the installer to determine in advance whether
the selected solar panel is suitable for the mounting system in terms of
dimensions and pressure loads. The calculated loads on the solar panel are
shown in the project report of the ValkPVplanner or are available on request
at Van der Valk Solar Systems.
Cable management
– Inorder to create a sound and durable electrical connection between the
solar panels, it must be ensured that the cables from the junction box have
sufficient length and thus do not cause any mechanical stress on the cable
glands. Take into account thermal expansion and contraction of cables and the
mounting system.
– Cables and connectors must be kept away from sharp and/or abrasive parts and
the roof surface by using sufficient and appropnate cable clamps and cable
baskets.
Disassembly and removal
– Components of the solar mounting system can be easily and completely
disassembled at the end of their service life and separated for recycling. The
systems only contain nut and bolt, screw and click connections, so nothing is
glued or welded. All materials are fully recyclable. Disposal of the
components always in accordance with the locally applicable laws and
regulations.

QR code.
When the consoles are properly installed on the respective roof, the Side++
profile can be attached to them using the hanger bolt clamp.
When fitting the hanger bolt clamp (721100), it is important to leave at least
1mm of thread above the clamp.
When fitting the hanger bolt clamp (721100), it is important to leave at least
1mm of thread above the clamp.
The aluminium profiles are mounted to the console with the hammerhead bolts.
The hammerhead bolts are placed in the slots of the profiles. When all bolts
are placed in the profile everything is fastened with the nut of the roof
hook. (max. torque is 15Nm).
There are 2 options available when mounting the console to the profile, these
are the 721100 and the 747895.
The groove on the hammerhead bolt corresponds with the orientation of the bolt head. Make sure the bolt is always mounted correctly.
Dilatations
The coupled system has to be dilatated after certain measurements, this needs
to be done because of the thermal expansion/contraction. For the aluminium
profiles this measurement is 30 meters. The minimal dilatation distance
between the profiles is 150 mm.
ValkSolarFix in combination with C+ profile
Standard parts for installation
The C+ profile can be mechanically anchored to the roof. These consoles with a
special height of 20mm can be fixed by:
– Toggle anchors for wooden or steel roof structures
– Concrete anchors for fixation in concrete roof structures
– Roof screws for fixation in wooden roof structures
– Roof screws for fixation in steel plate roof structures
– Roof screws for fixation in aerated concrete

When the consoles are properly installed on the respective roof, the C+
profile can be attached to them using the mounting set.
ValkSolarFix in combination with roof carrier
Standard parts for installation
The ValkPro+ system can be mechanically anchored to the roof. These consoles
with a special height of 20mm can be fixed by:
– Toggle anchors for wooden or steel roof structures
– Concrete anchors for fixation in concrete roof structures
– Roof screws for fixation in wooden roof structures

The 2™ nut on which the roof carrier rests allows you to clamp on the hanger
bolt at different heights. The max allowable clamp height on the hanger bolt
is 150mm
When the consoles are properly installed on the respective roof, the roof carrier profile can be installed on them. The console should be placed in the location where the tile carrier is normally installed. That is in the second slotted hole from the aluminium rear foot. In this case, the ValkSolarFix therefore replaces the tile carrier.
The ValkSolarFix can be mounted to the roof carrier with the mounting set (max torque = 8 – 14 Nm)
Fixation in combination with Side++ (VP+)
A second option for fixing the ValkPro+ to the roof is to attach the console
under the panel. In this case, a Side++ profile is attached to the console,
after which the Side++ profile is fixed to the roof carrier profiles on either
side of the panel. The Side++ profile should be attached in front of the
aluminium rear foot. This is in the first slotted hole from the aluminium rear
foot.
To properly attach the Side++ profiles, the corner brackets (729521) should be
fitted to the roof carriers on the side of the Side++ profile. The bracket is
hooked into the hammerhead chamber of the Side++ profile creating a
connection.
When fitting the hanger bolt clamp (721100), it is important to leave at least 1mm of thread above the clamp.
The aluminium profiles are mounted to the console with the hammerhead bolts.
The hammerhead bolts are placed in the slots of the profiles. When all bolts
are placed in the profile everything is fastened with the nut of the roof
hook. (max. torque is 15Nm).
There are 2 options available when mounting the console to the profile, these
are the 721100 and the 747895.
The advantage over fixation to the roof racks is that the fixation can be installed afterwards. This allows more flexibility during installation work. Please note, however, that the maximum forces of the fixation are lower.
The groove on the hammerhead bolt corresponds with the orientation of the bolt head. Make sure the bolt is always mounted correctly.
