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.

2. Planning

2.1 Determine the wind region of your installation site

Planning


03page of 55

Planning

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.

2.2 Determine the Terrain Category

This document provides sufficient information for the PV-ezRack® SolarRoof™ Tilt Legs 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


04page of 55

Planning

The PV-ezRack® SolarRoof™ Tilt Legs system can be used for roof slopes up to 30°. Please verify that the Installation site roof slope is between 0° and 30°.

2.4 Determine Roof slope

On the north facing roof, the angle of rear leg is between 30° and 90° with the roof plane.

On the south facing roof to make the panels facing the north (reverse tilt), the angle of rear leg should be no more than 90° with the horizontal.

30-60° adjutable tilt legs is certified for reverse tilt installation on the south facing roof. Please refer to Certification Letter and Tilt Legs Spacing Table.


05page of 55

Planning

On pitched roof, there are four different roof zones for installation. See the diagrams and steps below to determine area of each zone.

2.5 Determine the Installation Area of Roof

In the front figure h= height, b =width and d= length of the building.

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.

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.

4.2 Precautions during Stainless Steel Fastener Installation

4.2.1 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.


17page of 55

System Overview

4.2.2 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.

5.2 Rail Installation5.2.1 According to the installation plan, determine the mounting position of Rail.

To connect several Rails together, slide half of the splice into the rear side of the Rail. Fasten the first M8 Bolt using an Allen key, and slide the next Rail into the Splice as shown in Figure 11 and 12.Tighten the second M8 Bolt using an Allen key. The total Rail length is recommended not to be over 30 metersconsidering Rails thermal expansion problem. Splice provides the electrical connection between the 2 rails through the pressure bolts. This eliminates the need of using 2 earthing lugs.

Recommended torque for M8 bolts is 10~12 N·m

5.2.2 After confirming the position of Rail, fasten the Front and Rear Leg, as shown in Figure 13, 14 and 15.

Recommended torque for M8 bolts is 16~20 N·m

5.3 PV Module Installation

5.3.1 Deployment of Grounding Clips

1) When there is an even number of PV Module in each row: Install the grounding clips at the positions marked X in the Figure shown. Then the number of Grounding Clips = number of PV Module. Eg: 4 grounding clips as shown in Figure 16.

2) When there is an odd number of PV Module in each row: Install grounding clips at positions marked X in Figure shown. Then the number of Grounding Clips = number of PV Module +1. Eg: 6 grounding clips as shown in Figure 17.

Please note: When replacing a defective PV Module, it is required to replace the grounding clip under the defective PV Module.

5.3.2 Before installing the PV modules on horizontal rail installations, add anti-slip protection to the lowest row of PV modules. To do this, fasten M6 x 20 mm bolts (with the shank downwards) to the lower mounting holes of the PV module frame. When installing large modules (e.g. ASE250) M8 x 20 mm bolts must be used.

Figure 16

Figure 17

Figure 18

5.3.3 Place the PV Modules on to the rails and fix with End Clamps, Inter Clamps or Universal Clamps. Fasten with the Allen key.

-Solution 1 (Apply Standard Clamps)-Step 1 Place the first PV Module on the Rail according to your plan, and fix it in place using the End Clamps. Then fasten lightly with the Allen Key as shown in Figure 19 and 20.

Figure 20

Figure 19


23page of 55


-Step 2 Slightly lift the PV Module and click Inter Clamps and Grounding Clips into position. The teeth on Grounding Clip will automatically align when the Inter Clamp is properly installed as shown in Figure 21 and 22.

-Step 3 loosely place the next framed PV Module into the other side of the Inter Clamp and Grounding Clip as shown in Figure 23.

Important Notes: -To fix the Grounding Clip properly, ensure the frames of PV Modules are completely pressed against the Inter Clamps and Grounding Clips. 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 the PV Module is finalized. (Only slightly tighten bolts to keep PV Modules in place prior to the final check)

-Solution 2 (Apply Universal Clamps)

Step 1 Twisting the head of the Universal Clamp changes the functionality from End to Inter Clamp as shown in Figure 24.NOTE: Please ensure the Universal Clamp C-U/30/46 or Universal Clamp with Grounding Clip C-U/30/46-G is positioned correctly according to 5.3.1: Deployment of Grounding Clip.

Step 2 Incline the Universal Clamp to fit the lower channel against the lower channel of the Rail, and press the Universal Clamp down towards the other side to securely fit the upper channel against the upper rail channel, as shown in Figure 25.

Note: Before installation, make sure there is enough clearance between the screw and lower module of Universal Clamp as shown in Figure 26.

Step 3 Place the first PV Module on the Rails and apply the Universal Clamp in the End Clamp position and fasten slightly with the Allen Key. Make sure the frame of the PV Module is fully in contact with the Universal Clamp as shown Figure 27. Visually check the Universal Clamp and PV module are properly installed.


Figure 26

Figure 27

Step 4 When using as an Inter Clamp, click the Universal Clamp into the rail channel and slightly lift the framed PV Module to ensure the Grounding Clip is fully covered as shown Figure 28.

Step 5 Loosely place the next framed PV Module into the other side of the Universal Clamp. Ensure the Grounding Clip is fully covered and ensure the frame of the PV Module is in close contact with Universal Clamp as shown Figure 29.

Step 6 Repeat steps above to install all PV Modules. Visually check the Universal Clamps and PV modules are properly positioned and then fasten all Clamps. When you using Universal Clamps, the gap between two adjacent PV Modules is 20mm.The recommend torque for Universal Clamps in the End Clamp position is 13~14N·m.The recommend torque for Universal Clamps in the Inter Clamp position is 16~20N·m.

Figure 28 Figure 29


25page of 55


5.3.4 Install the remaining PV modules according to the steps above.

5.3.5 Fasten the bolts in the Front and Rear Legs after installed all the PV modules.Torque for M8 bolts please refer to 4.2.3 Safe Torques.

5.3.6 Apply one pre-assembled Grounding Lug per Rail. Slide the Grounding Lug into to the rail channel and fasten the bolt M8*25 with 16~20 N·m. Strip earthing cable (the maximum size is 10 mm2) and insert the conductor into the provided copper tube. Place the copper tube into the channel of Grounding Lug and tighten M6*10 with 5~6 N·m to ensure the earthing cable is tight.

Note: Check the electrical resistance between rail and earthing cable conductor to ensure the bonding is made.

There are three solutions for Grounding Lug installation:

-Solution 1Fix the Grounding Lug into the top channel of Rail as shown in the figure on the right.

-Solution 2Fix the Grounding Lug into the top channel of Rail where just under the PV Module as shown in the figure on the right.

-Solution 3 Fix the Grounding Lug at the side channel of Rail as shown in the figure on the right.

Definition of Roof Zones

1. For flush mounted systems installed on a pitched roof

Conditions: a. For pitched roofs where roof angle is between 1˚ and 30˚. b. h/d is equal or less than 0.5 and h/b is equal or less than 0.5 (h= height, b=width and d= length of

the building). *If any of the above conditions are not met, please go to case 2. Step 1: Determine the largest building dimension between the building width and length. Step 2: Divide the largest value in (Step 1) by 3. Step 3: Value obtained in Step 2 represents each zone length.

Upwind end, Downwind end = Edge Central, Upwind Central, Downwind Central = Middle




2. For flush mounted systems installed on a pitched roof Conditions:

a. For pitched roofs where roof angle is between 1˚ and 45˚.

In the front figure h= height, b =width and d= length of the building. 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.




3. For tilt array systems Condition:

a. For pitched roofs where roof angle is between 1˚ and 45˚.

In the front figure h= height, b =width and d= length of the building. 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.

PV Array Frame Engineering Certification

Installation of PV-ezRack ® SolarRoof Adjustable Tilt Legs with ECO-Rails (one screw)

Gamcorp (Melbourne) Pty Ltd, being Structural Engineers within the meaning of Australian

Building Regulations, have carried out a structural design check of PV-ezRack® SolarRoof Adjustable Tilt Legs installation within Australia and New Zealand. The design check has been based on the information in the PV-ezRack SolarRoof Adjustable Tilt Legs_Code Compilant Installation Guide_AU_V3.3 and schematic drawings and test reports of the system components by Clenergy (Xiamen) Technology Co. Ltd, provided by Clenergy Australia.

Our recommendations for the Installation of PV-ezRack® SolarRoof Adjustable Tilt Legs for Australian and New Zealand use are based on the following conditions:

• Wind loads to AS/NZ1170.2:2011 Admt 3-2013• Wind region A, B, C, D, W• Wind terrain category 2 & 3• Wind average recurrence interval of 500 years• Maximum building height 20m• Solar panels assessed are 1670mm x 999mm and 2000mm x 1000mm• Maximum weight of the PV panel and array frame to be 15 kg/m2

• 14g – 10 TPI Teks and M6 RoofZips screws are assessed for fixing into steel member• One fixing per tilt leg into steel is assessed for 0.48-0.9 BMT, 1.0 BMT, 1.2 BMT, 1.5

BMT, 1.9 BMT and 2.4 BMT steel members• 14g – 10 TPI (T17s) and M6 RoofZips screws with minimum embedment depth of

35mm are assessed for fixing into timber member• One fixing per tilt leg into timber is assessed for JD6, JD5, JD4, JD3, JD2, JD1 timber

members• M8 ChemSet anchor bolt with minimum embedment depth of 80mm is assessed for

fixing into concrete slab• One fixing per tilt leg into concrete is assessed for 20MPa, 32MPa and 40MPa concrete

slab• The interface spacing nominated is based on an assumption that the steel member,

timber member and concrete slab are in a good working condition• Rails to be ER-R-ECO• Each PV panel to be installed using 2 rails minimum in all circumstances• Installation of PV array to be done in accordance with the PV installation manual




Gamcorp (Melbourne) Pty Ltd A.C.N 141 076 904 A.B.N 73 015 060 240www.gamcorp.com.au Email: [email protected] 4, 346 Ferntree Gully Rd, Notting Hill VIC 3149. Tel: 03 9543 2211 Fax: 03 9543 4046

• The certification excludes assessment of roof structure and PV panels

Refer to attached summary table for interface spacing

NOTES:• The recommended spacing nominated in this certification is based on the

capacity of the array frame and limited fixings, not the roof structure and PV panel. It is the responsibility of the installer to adopt the most critical spacing.

• Under above mentioned conditions, the standard spacing tables to be applied for one fixing per tilt leg situation when specific spacing table is not provided.

• Any of the 3 holes can be used in the fix foot (drawing No. PZ01-1-003A-21) for the one screw fixing

• If any of the above conditions cannot be met, the structural engineer must be notified immediately.

Construction is to be carried out strictly in accordance with the manufacturers instructions. This work was designed in accordance with the provisions of Australian Building Regulations and in accordance with sound, widely accepted engineering principles.
