Introduction
1. Introduction
Clenergy PV-ezRack SolarTripod is suitable
for home, commercial, flat roof and even for
large scale solar installations. SolarTripod
divides 2 solutions, single row and double
rows in portrait of modules. The advantage of
SolarTripod is the pre-assembly fixed angle
brackets; it reduces the time and labour in
installation.
Please review this manual thoroughly before
installing PV-ezRack®SolarTripod ™. This
manual provides
1) Supporting documentation for building
permit applications relating to PV-ezRack®
SolarTripod ™ Universal PV Module Mounting
System;
2) Planning and installation instructions.
The PV-ezRack®SolarTripod ™ 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 do by contacting Clenergy Australia via
email on [e-mail], or contacting
your local distributor in Australia.
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;
• Ensuring that the roof, its rafters/purlins,
connections, and other structural support
members can support the array under building
live load conditions;
• Use only PV-ezRack parts as specified in this
document (substitution of any PV-ezRack part
may void the warranty and invalidate the letter
of certification);
•Recycling: Recycle: according to the local
relative statute;
•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;
•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.

2. Planning
2.1 Determine the wind region of your installation site
Planning
Region Definition:
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.
• Most of Australia is designated Region A which
indicates a Regional Wind Velocity of 43 m/s with
wind average recurrence of 200 years.
• Some areas are designated Region B (52 m/s).
Local authorities will advise if this applies in your
area.
• Region C areas (64 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 (79 m/s) is Australia's most extreme
Cyclonic Region, located between the town of
Carnarvon and Pardoo Station in Western
Australia.

This certification document provides sufficient information for the PV-ezRack®SolarTripod™ system
installation up to heights of 20 meters. If your installation site is more than 20 meters high, please contact
Clenergy to obtain project specific engineering certificate to support your installation.
2.3 Determine the Height of the Installation Site
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 few or no obstructions and enclosed, limited-
sized water surfaces at serviceability and ultimate wind speeds in all wind regions, e.g. flat, treeless,
poorly grassed plains; rivers, canals and lakes; and enclosed bays extending less than 10km in the wind
direction.
Terrain Category 1.5 (TC1.5) – Open water surfaces subjected to shoaling waves at serviceability and
ultimate wind speeds in all wind regions, e.g. near-shore ocean water; larger unenclosed bays on seas and
oceans; lakes; and enclosed bays extending greater than 10km in the wind direction. The terrain height
multipliers for this terrain category shall be obtained by the linear interpolation between the values for the
TC1 and TC2.
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 a few trees or isolated obstructions. This category is
intermediate between TC2 and TC3 and represents the terrain in developing outer urban areas with
scattered houses, or larger acreage developments with fewer than ten buildings per hectare. The terrain-
height multipliers for this terrain category shall be obtained by linear interpolation between the values for
the TC2 and TC3.
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 sized
obstructions per hectare, e.g. suburban housing or light industrial estates.
Terrain Category 4 (TC4) – Terrain with numerous larger, high (10m to 30m tall) and closely-spaced
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.

PV-ezRack®SolarTripod ™ system is certified to use for roof slopes up to 10°. If your installation site
is more than 10°, please contact Clenergy to obtain project specific engineering certificate to support
your installation.
2.4 Determine Roof slope
On pitched roof, there are four different roof zones for installation. See the steps below to determine
area of each zone.
2.5 Determine the Installation Area of Roof
Step 1: Determine building height, width and length;
Step 2: Multiply the width of the building by 0.2;
Step 3: Multiply the length of the building by 0.2;
Step 4: Determine lowest value between: (height of the building) and
0.2 × length of the building and 0.2 × width of the building;
Step 5: The lowest value in step 4, equates to a.
Please refer to the Certification Letter and Spacing Table. If a project specific Certification Letter has been
provided, please refer to the support spacing in this letter.
Rail end overhang should be not over 40% of the Tripod spacing. For example, if the Tripod spacing is
1500mm, the Rail end overhang can be up to 600mm only.
2.6 Determine the Maximum Rail Support Spacing
2.7 Verify Maximum Rail End Overhang
In the figure above h= height, b =width and d= length of the building.

(2) Length of rail in the same row: L1= Number of modules per row x (module width + 18mm) + 32mm.
(3) Distance between the two rows: L2 must be determine based on the location to avoid shading.
(4) Distance between the two support Tripod: L3 (refer to the Certification Letter).

-Single Tripod
System Overview
Improper operation may lead to the deadlock of bolts and nuts. Follow the steps below to reduce this
risk:
4.2 Precautionary Measures for Stainless-Steel Fastener Installation
4.2.1 Reduce the friction coefficient
(1) Ensure that the thread surface is clean (no dirt or contaminant).
(2) Apply lubricant (grease or 40# engine oil) to fasteners prior to tightening to avoid galling or seizing in the
threads.
4.2.2 General installation instructions
(1) Apply force to fasteners in the direction of thread.
(2) Apply force uniformly to maintain required torque.
(3) Professional tools and tool belts are recommended.
(4) Avoid using electric tools for final tightening.
(5) Avoid working at high temperatures.
4.2.3 Safe Torques
Please refer to safe torques defined in this guide as shown in the figure below. If 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, please make sure that there is no load on
the fastener before you cut it. Avoid damaging the anodized or galvanized surfaces.
