1. Introduction
The Clenergy PV-ezRack® SolarRoof™DC has
been developed as a universal PV-mounting
system for roof-mounting on pitched and flat
roofs. The use of patented aluminium base rails,
M-Module technology and telescopic mounting
technology eliminates custom cutting and
enables fast installation.
Please review this manual thoroughly before
installing PV-ezRack® SolarRoof™DC. This
manual provides:
1) Supporting documentation for building permit
applications relating to PV-ezRack®
SolarRoof™DC Universal PV Module Mounting
System,
2) Planning and installation instructions.
The PV-ezRack® SolarRoof™DC parts, when
installed in accordance with this guide, will be
structurally sound and will meet the Eurocodes
and VDI 6012 standard. During installation, and
especially when working on the roof, please
comply with the appropriate Occupational Health
and Safety regulations. Please also pay
attention to any other relevant State or Federal
regulations. Please check that you are using the
latest version of the Installation Manual, which
you can do by contacting Clenergy via email on
[email protected].
The installer is solely responsible for:
•Complying with all applicable local or national
building codes, including any that may
supersede this manual;
•Ensuring that PV-ezRack and other products
are appropriate for the particular installation
and the installation environment;
•Using only PV-ezRack parts and installer-
supplied parts as specified by the PV-ezRack
project plan. (substitution of parts may void the
warranty and invalidate the letter of
certification);
•Recycling: Recycle: according to the local
relative statute.
•Removal: Reverse installation process.
•Ensure that there are no less than two
professionals working on panel installation.
•Ensure the installation of related electrical
equipment is performed by licenced
electricians.
•Ensuring safe installation of all electrical
aspects of the PV array.
• Ensuring that the roof, its rafters/purlins,
connections, and other structural support
members can support the array under building
live load conditions;
•Ensuring that screws to fix interfaces have
adequate pullout strength and shear capacities
as installed;
•Maintaining the waterproof integrity of the roof,
including selection of appropriate flashing;

4. Installation Instruction
−The min. distance from the mounting rack to the roof edges is 3cm.
−Assess the horizontal spacing of the Roof Hooks.
−Check the allowed max. spacing as provided by the Calculation Tool “01-MR-
calculation tool - V1.0 for ER-I-DC/02A/CS(PV-ezRack SolarRoof Pro, Adjustable Tile
Interface, with carbon steel main body)”.
−Always check the installation manual of the PV-Module you use in order to determine
the allowed fixing points on the module frame.

4.1 Roof Hook Installation
4.1.1
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.
4.1.2
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:
If the rafter width is less than 5 cm,
6mm wood screw with rosette washer
as shown in the figure on the right is
needed.
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 3xd (screw
dia.)
The hook can only be mounted on the
roof rafter, cannot be mounted on tile
lath.
The wood connections are to
be made according to EN 1995-1-
1:2004+A1:2008

4.1.3
Use buffer plates to lift the tile bracket
so that the base does not rest on the
tile, as shown in Figure
4.1.4
If necessary, use an angle grinder to
cut a recess in the upper tile covering
the roof hook at the point where the
roof rook extends so that the tiles can
be placed properly.
4.1.5
Caution! Do not use fitted roof hooks
as a ladder, as this extreme point load
could damage the tile below.

4.2 Rail Installation
4.2.1
Insert the w module into the channel of
the rail, and fasten the M8 Torx screw
loosely with Torx L-key or the
equivalent.
Please refer to the figures on the right
for height adjustment.
The roof hook should not protrude over
the rail after the adjustment.
4.2.2
In the cases that double layer (cross
rail) is required for the installation,
please use cross connector and
grounding clamp to fix the top and the
bottom rails.
Place the rails on the bottom rails and
fix two rails together.
.
When using the cross connector 2.0
ER-CC-DC50/2, Click the M-module
into the top channel of DC rail 50 at
any given point, move the cross
connector 2.0 close to the rail and
fasten the M8 Torx screw loosely as
shown on the right figures.
When using the grounding clamp 2.0
ER-RC-DC50/G/2, click the M-module
into the top channel of DC rail 50 at
any given point, move the grounding
clamp 2.0 towards to the opening
