PREPARATION

Required tools:

• Measuring tape
• Measuring profile
• Spiral drill
• Hexagon socket 10mm
• Hexagon bit 8mm

1. Check that the roof subsurface is sufficiently strong (replace if necessary).
2. Observe the NEN standards at all times.
3. Before installing, clean the roof thoroughly and measure any obstacles or barriers before you start mounting. Always start your installation from north to south

BEFORE YOU GET STARTED

Mounting a PV system changes the building load, which may affect the load- bearing structure. You should therefore have a qualified technician recalculate this load. In doing so, take account of the latest regulations, especially NEN 6702, NEN 7250, NEN1991-1-4 A1 + C2/NB and NEN 1991 1-3.

Also ask the insurer and the designer to approve:

• the loads on the building due to the additional weight of the PV system;
• the loads on the building due to the changed geometry of the roof plan;
• the loads on the building due to the dynamic wind pressure and precipitation;
• the loads on the building, the roofing and the insulation during mounting;
• the load of the contact points on the compatibility of the insulation and roofing;
• the compatibility of the roofing with the load-bearing structure at the contact points;
• the mutual effects from the thermal activity of the building and the PV system;
• the effects from possible movements in the roof and the PV system.

While care has been taken when producing the calculations and dimensions in the Blubase calculation tool, no rights can be derived from them. The prices are indicative and may vary; for example, due to rising prices of raw materials. You can find the general terms of delivery on blubase.com.

FREE EDGE REGION
NEN 7250 stipulates that solar panels should not be mounted all the way to the edge of the roof, where strong wind turbulence may occur. The region around the edge of the roof should therefore be free of solar panels: the free edge region. If you are mounting solar panels on roofs over 12 metres, you may need to take additional measures. Please consult your contact person. Measure the free edge region from the outer border (see the blue border in Figure C). You can look up the size of the free edge region in the table. This information is also available in the ballast plan.

EQUALISATION
The Magnelis steel and the aluminium take care of equalisation. They prevent tension from building up in the material and failures from occurring in the inverters or microinverters. (NEN 1010:2015

MOUNTING PLAN

STAP 1
Use the mounting plan and the ballast plan from the Blubase calculation tool. Determine the first mounting point within the free edge region (see Page 5) and continue working North to South from there.

UNDERLYING ELEMENTS

STAP 2
ake the basic component and always click the stand to its upright position first. Place the basic component on the first mounting point. Next, take the connector and click it into place at the front. Please note: you should be able to hear a clear click, which means that the barb entered into the hole correctly.

TIP: If you are working on a gravel roof, consider the use of our raising blocks. These blocks fit neatly underneath the bases of a basic component. As a result, the mounting system will be raised and will not move.
TIP: It is crucial that you maintain straight lines and 90-degree angles when mounting. Only then will the solar panels connect to the stands. One solution is to use a mason’s line; see the example.

STAP 3
Connect the second basic component to the first and click another connector into place. Continue with the next basic components and connectors until the first row has been finished according to the mounting plan.

EAST-WEST SET-UP
In case of an East-West set-up, you must rotate the basic component and use the East-West connector. Move the stand to its upright position before you click the connectors into place.

STAP 4
Place the second row in the exact same way as the first row. The length of the solar panel determines the spacing between the rows. Place the second row in the exact same way as the first row. The length of the solar panel determines the spacing between the rows. Determine the exact distance using the Measuring profile. Repeat these steps for all rows to carry out the mounting plan. The next page contains instructions on using the Measuring profile.

USING THE MEASURING PROFILE

Place the Measuring profile (A) across the breadth of the panel, push home the slide (B) and turn it tight using the knob (C).

TIP:
From the outset, be sure to use right angles of 90º. If you do, the mounting system will always be straight and the solar panels will always fit.

BALLAST BOXES

STAP 5
Place the ballast boxes containing the ballast in accordance with the mounting plan. It is not required to screw down the boxes. However, you are advised to do so in case of large projects, as this process prevents the system from moving. The basic component has already been fitted with rough-drilled holes.

SOLAR PANELS

STAP 6
Place the solar panels against the mounting points. Next, conceal the cables in the cable management system.

Click the clamps into the basic component and turn them tight (torque of 8–10 Nm).

CABLE MANAGEMENT

STAP 7
Place the string cable through the upper ridge of the cable conductor at the inside of the stand. It should be easy to place the return cable on the outside through the front cable conductor. The cable tray contains a shielded area for the other cables.

TIP:
Are you using optimisers or microinverters? Place them in the base of the basic component and slide them into place until they click.

REAR PANELS

STAP 8
Place the rear plates in the fastening points at the bottom of the stand. Each stand has two rough drilled threaded holes (top and bottom). Use both for the stands at the edge of the field, but only the top one for the stands in the centre. The screw torque is 5 Nm.

SIDE PANELS (OPTIONAL)

STAP 9
Side plates are optional. When using them, click them into the bottom of the basic component and fasten them to the mounting point of the stand using a single screw.

GROMMET (OPTIONAL)

STAP 10
Grommets are available for side plates and basic components. They conduct the cables without risking cut-ins or cracks.

RAISING BLOCK (OPTIONAL)

STAP 11
If you are working with gravel or you wish to elevate the mounting system for another reason, consider the use of our raising blocks. They fit neatly underneath the bases of a basic component.

DISCLAIMER

BLUBASE

• This manual is a general guide (and is therefore not specific to one project) for the straightforward and efficient installation of solar panels using the Blubase mounting system. No rights may be derived from this manual.
• For the installation of the Blubase connect mounting system the buildings should have a height of max. 12 metres. If the building is taller, please contact Blubase in advance for a project specific, customised solution.
• If a flat roof is sloping more than four degrees, the Blubase connect mounting system must be secured/anchored to prevent movement.
• An online calculation tool is available for the ballast calculation. Although this tool was developed in collaboration with the TNO Bouw research organisation according to NEN 7250, the results should be used as a guideline only. Blubase does not supply any ballast material.

IMPORTANT

• Installing solar panels on an existing building will change its structural load and/or construction. We therefore recommend that the structural calculations for an existing building are updated by a specialist, taking into account the solar panels to be placed and current regulations such as NEN6702, NEN7250, NEN1991-1-4+A1+C2:2011/NB:2011 and NPR 6708:2013 in particular for wind, snow and water loads.
• The building insurer must be contacted in advance.
• The following building-related elements should be checked and approved in view of the existing structural arrangements:
  • The additional weight load of the entire PV system that will be installed
  • Geometry change of the roof surface
  • Wind pressure, snow load and water load, with simulation of accumulations
  • The loads for the structure, roof coverings and insulation during the installation
  • The suitability of the roof covering and insulation (point pressure) at the contact points between the mounting system and the existing construction
  • The consequences of the thermal interaction between the building and the PV system
  • The consequences of any vibrations of the building and/or PV system
