Precautions during Stainless Steel Fastener Installation
Improper operation may lead to deadlock of Nuts and Bolts. The steps below should be applied to stainless steel nut
and bolt assembly to reduce this risk.
General installation instructions:
(1) Apply force to fasteners in the direction of thread
(2) Apply force uniformly, to maintain the required torque
(3) Professional tools and tool belts are recommended
(4) In some cases, fasteners could be seized over time. As an option, if want to avoid galling or seizing of thread, apply
lubricant (grease or 40# engine oil) to fasteners prior to tightening.
Installation Guide / SolarRoof
Safe Torques
Please refer to safe torques defined in this guide as shown in the figures below. In case power tools are required,
Clenergy recommends the use of low speed only. High speed and impact drivers increase the risk of bolt galling
(deadlock). If deadlock occurs and you need to cut fasteners, ensure that there is no load on the fastener before you
cut it. Avoid damaging the anodized or galvanized surfaces.

− The min. distance from the mounting rack to the roof edges is 20cm.
− Assess the horizontal spacing of the Roof Hooks;
− Assess the vertical spacing of the Roof Hooks = approx. 1⁄2 to 3⁄4 of module height;
− Check the allowed max. spacing listed in this installation guide.

− The min. distance from the mounting rack to the roof edges is 20cm.
− Assess the horizontal spacing of the Roof Hooks;
− Assess the vertical spacing of the Roof Hooks = approx. 1⁄2 to 3⁄4 of module height;
− Check the allowed max. spacing listed in this installation guide.
− Always check the installation manual of the PV-Module you use in order to determine the allowed fixing points on
the module frame.
Installation Guide / SolarRoof
Fix the roof hooks to the rafter using M8*100 Torx screw
as shown in the figure on the right following screws
installation guide below:
- Use a 3/8" Torx Socket.
- Use a powered or cordless screw driver.
- Fit the driver bit into the screw and place at the
fastening position.
- Apply consistently firm pressure (end load) to the screw
driver until the screw is fastened.
Note: Only approved and certified wood screws are to be
used for roof hook installations. A predrill 5mm dia. hole
is needed and the distance between the screw to rafter
edge is 3×d (screw dia.)
The hook can be installed only on the roof rafter but not
on the tile lath.
The roof hook must not press against the roof tile. If
necessary, pack the roof hook.
Determine the positions of the roof hooks according to
your plans. Remove the roof tiles at the marked positions
or, if possible, simply push them up slightly.
Alu Hook Installation
If necessary, use an angle grinder to cut a recess in the
tile covering the Roof Hook at the point where the Roof
Hook extends so that the tile lies flat on the surface. If
grooved tiles are used, it will also be necessary to cut a
recess in the lower tile.
5mm spacing between the lower side of arm and tile is
recommended as shown in the figure on the right.

Caution! Do not use fitted roof hooks as a ladder, as this
extreme point load could damage the tile below.
To connect several rails together, slide half of the splice into the rear side of the rail, until it’s stuck and fixed by the
Connection Clip. Then slide the next rail into the splice and get it fixed.
The installation location of the splice is as shown in the figure below.
Place the rails on the Upper Clamp for L Bracket, and fasten the M8 Torx screw loosely with Torx L-key or the equivalent.
The recommended torque is 14N•m.
Please refer to the figures on the right for adjustments.
The adjustable range are shown in the figure below.

Note: If PV modules are installed in landscape, the
rail need to running parallel to the rafter, as shown
in the figure on the right.
Place PV Modules on rails, fix with end clamps and
inter clamps. Click the M-module of the clamps
into the top channel of rail as shown in the figures
on the right.
Step 1 Place the first PV Module on Rails according
to your plan and apply the End Clamps to fix it
and then fasten lightly using Torx L-key or the
equivalent as shown on the right figure.

Notes:
The distance L from end clamp to the end of the rail shall
be over 10mm.
Step 2 Slightly lift the PV Module and slide Inter
Clamps and Grounding Clips into position. The teeth on
Grounding Clip will automatically align when the Inter
Clamp is properly installed as shown on the right figures.
Step 3 loosely place the next framed PV Module into
the other side of the Inter Clamp and Grounding Clip as
shown on the right figure.
Important Notes:
- To fix the Grounding Clip properly, ensure the frames
of PV Modules are completely pressed against the Inter
Clamp and Grounding Clip. Visually check that Grounding
Clips are positioned properly.
- Grounding Clips are intended for SINGLE USE ONLY!
- Only fasten the bolts down when the position of PV
Module is finalized. (Only slightly tighten bolts to keep PV
Modules in place prior to the final check)
Step 4
Maintain 20mm vertical gap and 20mm horizontal gap
between the two adjacent rows of PV Modules.
You can use two Inter Clamps to separate two PV
Modules, and remove after installation as shown on the
right figure.
Double check if all PV Modules are fixed properly.
Fasten all the screws tightly with the recommended
torque 14N•m.

20mm
Verify Maximum Rail End Overhang
Rail end overhang should be not over 40% of the interface spacing. For example, if the interface spacing is 1500mm,
the Rail end overhang can be up to 600mm only.
The rail installation are completed as shown in the figures below.
