Introduction
Using only PV-ezRack® parts and installer- supplied
parts as specified by 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.
Ensuring that there are no less than two professionals
working on panel installation.
Ensuring the installation of related electrical
equipment is performed by licenced electricians.
Ensuring safe installation of all electrical aspects of
the PV array, this includes adequate earth bonding of
the PV array and PV-ezRack® SolarRoof components
as required in AS/ NZS 5033-2014 AMDT 2 2-2018.
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
pull-out strength and shear capacities as installed.
Maintaining the waterproof integrity of the roof,
including the selection of appropriate flashing.
Verifying the compatibility of the installation
considering preventing electrochemical corrosion
between dissimilar metals. This may occur between
structures and the building and also between
structures, fasteners and PV modules, as detailed in
AS/NZS 5033: 2014.
Verifying atmospheric corrosivity zone of installation
site by referring to AS 4312-2008 or consulting local
construction business to determine appropriate
products and installation.

The PV-ezRack® ComT is developed for PV installation
on flat or pitched roofs. The unique fixing parts can be
quickly and easily installed with simple tools.
Please review this manual thoroughly before installing
PV-ezRack® ComT. This manual provides:
1) Supporting documentation for building permit
applications relating to PV-ezRack® ComT.
2) Planning and installation instructions.
The PV-ezRack® ComT parts, when installed
in accordance with this guide, will be structurally
sound and will meet the AS/ NZS1170.2:2011 Amdt 2-
2016 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 obtain
by contacting Clenergy Australia via email at tech@
clenergy.com.au or contacting your local distributor in
Australia.

Planning
Most of Australia is designated Region A which
indicates a Regional Wind Velocity of 45 m/s with
wind average recurrence of 500 years.
Some areas are designated Region B (57 m/s). Local
authorities will advise if this applies in your area.
Region C areas (69 m/s) are generally referred to as
Cyclonic and are generally limited to northern coastal
areas. Most Region C zones end 100km inland.
Region D (88 m/s) is Australia's most extreme Cyclonic
Region, located between the town of Carnarvon and
Pardoo Station in Western Australia.

Wind regions are pre-defined for the whole of Australia by the Australian Standard 1170.2. The Wind Region is an
independent factor of surrounding topography or buildings.

Determine the Terrain Category
You will need to determine the terrain category to ensure the installation meets the required standard.
Terrain Category 1 (TC1) – Very exposed open terrain with very few or no obstructions, and all water surfaces, e.g. flat,
treeless, poorly grassed plains; open ocean, rivers, canals, bays and lakes.
Terrain Category 2 (TC2) – Open terrain, including grassland, with well-scattered obstructions having heights generally
from 1.5m to 5m, with no more than two obstructions per hectare, e.g. farmland and cleared subdivisions with isolated
trees and uncut grass.
Terrain Category 2.5 (TC2.5) – Terrain with some trees or isolated obstructions, terrain in developing outer urban areas
with scattered houses, or larger acreage developments with more than two and less then 10 buildings per hectare.
Terrain Category 3 (TC3) – Terrain with numerous closely spaced obstructions having heights generally from 3m to 10m.
The minimum density of obstructions shall be at least the equivalent of 10 house-size obstructions per hectare, e.g.
suburban housing, light industrial estates or dense forests.
Terrain Category 4 (TC4) – Terrain with numerous larger, high (10m to 30m tall) and closely-spaced constructions
buildings, such as large city centers and well-developed industrial complexes.
If your installation site is not at TC 2, 2.5 or 3, please contact Clenergy to obtain a project specific engineering certificate
to support your installation.
Verify Atmospheric Corrosivity Zone of Installation Site
Please refer to “AS 4312-2008 Atmospheric Corrosivity Zones in Australia” or consult a local construction business to
verify the corrosivity category of the installation site to determine appropriate products and interface spacing. When
standard products are installed in high corrosivity zones, like C4/C5, interface spacing reduction factor needs to be
applied. Please refer to the generic note of the Certification Letter for details.
Determine the Height of the Installation Site
This document provides sufficient information for the PV-ezRack® ComT system installation up to heights of 30 meters.
If your installation site is more than 30 meters high please contact Clenergy to obtain a project specific engineering
certificate to support your installation.

Determine System Tilt Angle
The PV-ezRack® ComT system is a fixed 5°, 10° and 15° tilt system.
Determine Roof Pitch
The PV-ezRack® ComT system can be used for roof slopes up to 10°. Please verify that the Installation site roof pitch is
less or equal to 10°.
Determine the Installation Area of Roof
Please refer to PV-ezRack® ComT Interface Spacing Table in Certification Letter.
Verify Rafter/Purlin Properties of Building
Please verify the rafter/purlin properties of the building, which could affect the interface spacing. For example, the tin
interface spacing on the metal purlin in the certification letter is based on steel purlins G450 1.9 mm thick. If the steel
purlin is less than 1.9 mm in thickness, the corresponding reduction factor of the interface spacing will be applied. For
different grade of timber purlin, the different spacing will apply as well. Please refer to the generic notes for details.
Determine the Maximum Rail Support Spacing
There are other additional factors (such as PV module dimensions, number of rails per PV module, row spacing
between PV modules) related to maximum rail support spacing. Please refer to the notes of Certification Letter. If a
project specific Certification Letter has been provided, please refer to the support spacing in the provided letter.
Verify Maximum Rail Overhang
Maximum rail overhang is 150 mm for interface fixing (or installed) spacings equal or over 700 mm. For interface fixing
spacings less than 700 mm, max rail overhang is 50 mm.
Verify PV Module’s Clamping Requirements
It is important to check PV modules clamping requirements (for example clamp dimensions, clamping distance from
the end of panel) from PV modules manufacturer before installations, which can help to avoid using incorrect size of
clamps and help to plan interface’s positions on the roof and rail’s orientation and position.
