Safety instructions for roofs

Solar mounting systems installed on roofs will be exposed to wind and snow.

The building in question will be subject to a greater load as a result of the PV system. A design calculation must be used to establish whether or

not the building in question will be able to withstand the extra load. Where necessary, modifications need to be made.

The standards applied (if applicable for specific solar mounting system)

Application

To calculate the needed strength, ballast and foundation of the solar mounting system, according the Eurocodes, the specific location details

have to be determined, e.g. wind zone, snow zone and height of the building. These need to be entered in the 1-2-3 PV Planner.

Foundations and strength of field systems are calculated with SolarTop.

Type of solar panel

The Van der Valk Solar Systems mounting systems are universal mounting systems for solar panels. Almost any solar panel with of without an

aluminium frame, possibly with mounting holes, can be mounted.

Types of roof

Type of roof covering: bitumen, EPDM, PVC, concrete and other roof coverings. For ballast calculations the exact roof covering must be known.

Before installing the solar mounting system, make sure that you carefully sweep the roof area.

The ballast calculation for flat roofs only applies for roofs with a slight pitch of up to 5°. Above this roof pitch, the system needs to be attached to

the roof securely.

Ballast

Flat roof systems can be attached to the roof or need to be supported by ballast, to make sure that the system is unable to move, lift or tip over.

The components supplied do not fully include the ballast required, which will be a number of tiles with a certain measurement and weight.

The number of tiles required per position, per type of solar panel, per roof area and per building height is calculated via the 1-2-3 PV Planner

and can be seen in the installation instructions and foundation adivse. The number of tiles specified per position will be vital to ensure that the

mounting system can be used safely.

Position

Restrictions also apply for the position of the system on a roof. The solar panels must be installed at a certain distance from the

edge of the roof. Follow the scheme in the installation manual calculated by the 1-2-3 PV Planner.

Guarantee

The guarantee provided is subject to the guarantee conditions stated in the general terms and conditions stipulated by

Van der Valk Solar Systems BV. Our terms and conditions can be found on our website: www.valksolarsystems.nl.

EN — GB

Congratulations on buying the ValkDouble® mounting system and on helping the

environment by deciding to install solar panels. The ValkDouble®

mounting system is an universal mounting system that can be used to install 2 standard solar panels in a landscape set-up one above the other, with a tilt angle of 10°, on a flat roof with a height up to 10 m. The components supplied do not include the additional ballast required, which will be a number of tiles. The weight of tiles required per position, per type of solar panel, per roof area and per building height is specified in the tables on page 8 of this document.

Safety instructions

The ValkDouble® mounting system shall be installed on roofs and will be exposed

to wind and snow. The building in question will be subject to a greater load as a result of the solar system. A design calculation must be used to establish whether or not the building in question will be able to withstand the extra load. Where necessary, modifications need to be made. When installing the ValkDouble® mounting system, the instructions provided in this “User manual” must be observed at all times. Read this manual carefully and keep it in a safe place. Also follow the instructions stated in the manuals of the other system components that form part of the overall solar system. All current structural, safety and building regulations must be observed. Van der Valk Solar Systems B.V. will never be liable for any direct and/or indirect intangible or consequential loss ensuing from or connected to the failure to observe the instructions provided in this manual.

produced by: Van der Valk Solar Systems B.V., Registered with the chamber of commerce for Haaglanden under number 27355116. Internet: www.valksolarsystems.nl

Type of solar panel The ValkDouble®

mounting system is an universal mounting system for solar panels. The following starting points apply: Panel design : Standard solar panels with an aluminium frame. Panel length : Approx. 165 cm Panel width : Approx. 100 cm Thickness of the aluminium frame : 28 - 50 mm Panel weight : Approx. 20 kg

Types of roof

The ValkDouble® mounting system can be used to mount panels on flat roofs. The following starting points apply:

Type of roof covering: bitumen, EPDM and concrete (for the ballast applicable per type of roof covering, see the tables on page 8 of this docu-ment). Before installing the ValkDouble® mounting system, make sure that you carefully sweep the roof area. The ballast calculation for the ValkDouble® mounting system (see page 8 of the manual) only applies for flat roofs and roofs with a slight pitch of up to 5°. Above this roof pitch, the system should be attached to the roof securely.

Ballast

The ValkDouble® mounting system needs to be supported by ballast, to make sure that the system is unable to move, lift or tip over. See page 8 of this document for details of how many ballast should be used for each type of solar panel, each region, each type of roof covering and for each building height (subject to a maximum of 10 m). The weight specified per position will be vital to ensure that the mounting system can be used safely. To achieve this, follow the instructions on the ballast required on page 8 of this document.

Position

Restrictions also apply for the position of the system on a roof. The solar panels must be installed at a certain distance from the edge of the roof. According to the current standard, NEN-EN 1991-1-4, this free edge zone is 1/5 of the height of the roof. So, if a roof is 6 metres high, a free edge zone of 120 cm will be necessary. Guarantee The guarantee provided is subject to the guarantee conditions stated in the general terms and conditions stipulated by Van der Valk Solar Systems B.V. Our terms and conditions can be found on our website: www.valksolarsystems.nl.

Ballast requirements

General The ValkDouble® mounting system must be weighted down by tiles, which will be placed at position G2. Start by choosing the wind area in which the system will be installed from the overview on page 8. Next, look at the table for the panel length in question. In this table, you will choose the relevant type of roof covering. Bitumen and EPDM have a higher frictional resistance and it will be possible to use less ballast for this type of roof covering. Next, choose the table for the wind area in question and the row for the building height applicable. This will show you the weight necessary for position G2.
