Introduction

� The Ubbink Solar On-Roof systemis designed for mounting all typesof photovoltaic (PV) modules onto tiled or slate roofs.

� The system provides securemouting without compromisingthe integrity of the roof.

� All pitched roofs from 15° to 70°, can be catered for

� The system is suitable for fittingmodules to existing roofs, or fornew build applications.

� The Ubbink Solar On-Roof system is guaranteed for 10 years,providing installation has beencarried out correctly.

Planning the module layout

1. Number of modules in the vertical direction x module height(plus the distance between thevertical modules if necessary)

2. Number of modules in thehorizontal direction x (modulewidth + 20mm) + 50mm

3. Vertical spacing of the roof hooks =approx 1/2 to 3/4 of module height(please also consult therecommendations of the modulemanufacturer if others are beingused)

4. Distance between the modules:20mm

Caution: The distance required according to DIN 1055 can vary widely depending on the height of the building, wind load, snow load, terrain category and roof pitch!

Overview of required tools� 5mm Allen key� Cordless drill with Torx-30

(AW 30) bit� Open-end spanner set 9, 13,

19mm (recommended: ratchet)� Angle grinder with stone disk� String (for alignment)� If necessary, wood to shim the

roof hooks


3. Maximum spacing allowed of roof hook is 828mm

4. Vertical spacing of the roof hooks = approx 1/2 to 3/4 of module height (please also consult the recommendations of the module manufacturer if others are being used) 5. Distance between the modules: 20mm

Installation


Determine the positions of the roof hooks according toyour plans. Remove the roof tiles at the marked positionsor, if possible, just lift them up slightly.

1

Fix the roof hooks to the rafter using using 2 no. 7mm x85mm wood screws.2

3

4

The roof hook must not press against the roof tile. Ifnecessary, shim the roof hook with wood.

If necessary, use an angle grinder or hammer to cut arecess in the tile covering the roof hook at the placewhere the roof hook comes through so that the tile lies flat.

If grooved tiles are used, it will also be necessary to cut arecess in the lower tile.


Minimum rafter/truss size should be 37mm x100mm,subject to survey.


5 Important information

Caution! Do not use fitted roof hooks as a ladder, as thisextreme point load could damage the tile below.

Different installation on plain tile roofs

With plain tile roof cladding, a recess must be cut into thetiles around the position of the roof hook.

Base rail installation

Attach the rails loosely to the roof hooks or L-bracketsusing the hammer-head bolt and the serrated nut. Pleaseensure that the hammer-head bolt is vertically positionedin the rail channel after tightening.

The slotted hole in the roof hook allows optimaladjustment of the height of the rails.

Position the first rails align them with one another andthe roof cladding, make sure the rails are parallel. Thentighten the nuts that are used to fasten the rails to theroof hooks/hanger bolts (recommended torque 8Nm).

When there is a portrait installation, the rails need to beinstalled horizontally. when there is a landscapeinstallation, the rails needs to be installed vertically.

Installation continued

Then insert the next rail firmly into the connector, untilthe rivet is no longer visible and the rails are touching.The connection is then complete.

The rivet ensures that the connector is inserted in bothrails equally.

Module installation

Before installing the bottom modules should be providedwith anti-slip protection (only with horizontal railinstallation). To do this, tighten M6 x 20mm screws (withthe shaft downwards) with M6 nuts in the bottomfastening holes of the module.

Lay the modules of the bottom line so that the anti-slipprotection of the frame is against the bottom rail.

Install the modules with the clamps as shown in thedrawing: Push the module end clamp sideways onto theframe rail. The end clamps can be adjusted to the heightof the module frame by turning the Allen bolt anti-clockwise using the Allen key, then secured (torque 9 -10Nm).

The mid clamps can be attached anywhere on the frame.Hook one side of the clamp behind the upper edge of theframe rail and push down until it clicks audibly into place.The mid clamps can be adjusted to the height of themodule frame by turning the Allen bolt clockwise usingthe Allen key and then fastened (torque 9 - 10 Nm).

Installing connectors with rails

Connectors are required to connect several rails together.

First, insert the connector into the already mounted railas far as it can go.

10



Before installing the bottom modules, you are provided

Place the last module in the row on the rails and securethe last module with the end clamp using the Allen key(torque 9 - 10 Nm).

15

Now slide in the first module in the next row from aboveonto the corresponding module of the row beneath. Somedistance can be maintained from the lower module foroptical reasons. A mid clamp can be used as a spacer toensure that the vertical and horizontal gaps between themodules are of identical sizes. Continue installing theother modules according to steps 14 to 16, until all themodules have been installed. Installation complete.

Please note: This system is not suitable for use withcorrugated fibre cement roofs. Please contact Ubbink for further information.



Ubbink solar mounting systems overview

Ubbink Solar In-Roof System

The Ubbink Solar In-Roof mountingsystem integrates PV modules intoslate or tiled roofs, ensuring an attraciveand low profile appearance. The systemis fully watertight and easy to install.The Ubbink Solar In-Roof mountingsystem is typically installed on newroofs where it reduces cost as tiles orslates are not required below the PV array.

Ubbink Solar On-Roof System

The Ubbink Solar On-Roof mountingsystem is simple, fast, economical andsuitable for all slate and tiled roofs. The PV modules are fixed to amounting assembly just above theexisting roof. The Ubbink Solar On-Roofmounting system is typically installedon existing roofs.

Ubbink Solar Flat Roof System

The Ubbink Solar Flat Roof mountingsystem positions PV modules to facesouth at the optimal angle. This is amodular ballasted system that sits onthe flat roof ensuring no roofpenetration from fixings through theroof membrane. This system can befitted and positioned very quickly onflat roof buildings up to 25m high.
