STRUCTURAL DESIGN CERTIFICATE

Project Description: Fixing Centres for Trina Mount II Photovoltaic Mounting

System as detailed in

Trina Mount II Code Compliance Report (Australia), v1.0

We, Partridge Partners Pty Limited, being professional Structural Engineers within the

meaning of the Building Code of Australia, hereby certify that we have reviewed the

structural design of the fixing centres for the Trina Mount II Photovoltaic Mounting

System as detailed in the tables (Trina Mount II Span Tables, 4 no.) provided in the “Trina

Mount II Code Compliance Report (Australia)”, v1.0, dated October 31, 2011, and that the

calculations used to derive these fixing centres are in accordance with the relevant

provisions of the Standard Building Codes, in particular AS/NZS1170.2:2011, and in

accordance with accepted engineering practice and principles.

This certification is subject to the limitations imposed on the system by the manufacturer

and as detailed in the Code Compliance Report. The structural capacities of the system

components have been derived by others from testing. This document does not constitute

certification of the existing roof structure to which the mounting system is to be fixed.

Adequacy of the existing structure should be determined on site by the installer prior to

installation.

This certificate shall not be construed as relieving the system manufacturer or installer of

their responsibilities, liabilities or contractual obligations.

Trina Mount II Code Compliance Report (Australia)

The attached span tables for Trina Mount II photovoltaic mounting system have been

designed in accordance with the structural requirements of the Australian Standard 1170.2

(AS1170.2:2011).

Trina Mount II consists of Big Feet, Cam Feet, Interlocks, Hybrid Interlocks, and Ground

Lugs that connect the edge frames of photovoltaic modules designed to mate with Trina Mount

II. The system has been analyzed for Trina Mount PV modules with maximum dimensions of

992 mm by 1660 mm. The Leveling Feet may be mounted to the following roof types with the

methods listed:

A. Custom Orb corrugated metal roofing

B. Trimdek metal roofing

• Big Foot mounted to the metal deck and screwed into either wood or metal

battens.

The attached tables define maximum Leveling Foot spacing requirements for a range of

Terrain Categories, Wind Regions, roof zones, and roof pitches. The attachment spacing values

in the tables are calculated based on allowable upward, downward, and lateral load values.

These load values are determined from manufacturer provided test data for independently

manufactured products, first principle calculations, and tests conducted using a calibrated load

cell. The tables are based on the conditions illustrated in the attached sketches and listed

below:

1. Terrain Categories 1, 2, 3, and 4 as defined by AS1170.2:2011.

2. Roof wind zones Interior, Edge 1, Edge 2, and Corner as defined by AS1170.2:2011.

3. Maximum Roof Height is 10 meters and roof pitch is between 0ᵒ (flat) and 45ᵒ

(12:12). See tables for specific slope subsets [0-14ᵒ (flat to 3:12), >14-27ᵒ (>3:12 to

6:12), >27-37ᵒ (>6:12 to 9:12), >37-45ᵒ (>9:12 to 12:12)]. For average roof heights

greater than 10 meters contact Trina Solar for reduced spans.

4. Modules installed in “landscape” orientation have the long sides of the modules

parallel to the battens that run across the roof slope. Modules installed in “portrait”

orientation have the long sides of the modules running perpendicular to the battens

and parallel to the roof slope (see sheet 4). In both module orientations, the Big Feet

and Interlocks are positioned on the module edges that run with the slope of the

roof, perpendicular to the battens.

5. The Importance Level is 2.

6. Building is not located on a bluff or near the top of a hill (i.e. Topographic Multiplier

= 1.0 per AS1170.2:2011).

7. Direction multiplier is equal to 1.0 (i.e. any direction).

8. Shielding multiplier is equal to 1.0 (i.e. no shielding).

9. The bottom of the “Rockit” is a maximum of 25mm above the top of the leveling

foot as shown on sheet 5.

10. The tables apply to roofs with Custom Orb or Trimdek metal roofing and wood or

metal battens.

11. Timber battens must have a minimum thickness of 35mm and be from joint group J4

or better. Steel battens must have a minimum thickness of 0.75mm and be Grade

550 or better.

12. Fasteners are always located at the crest of the roof sheet.

13. For timber battens, use 6.3mm diameter 14G timber screws with a minimum

embedment of 35mm. For steel battens use 6.3mm diameter 14G steel or Tek

screws.

14. EPDM pads or equivalent method shall be installed between the roof cladding and

the Big Foot to assist in waterproofing and provide galvanic separation.

15. Installer is responsible for verifying that all assumptions and limitations are met

when applying the attached foot spacing tables.

16. Conditions outside the assumptions and limitations listed and illustrated for the

attached tables may be feasible, but shall be designed in consultation with Trina

Solar, and, where appropriate, reviewed by a licensed professional engineer. Refer

to the Trina Solar online design tool (trinamount-design.com) for additional design

parameters.

17. If attachments are made to every batten, the existing framing shall be deemed to be

adequate to support that additional loading of the PV system. If battens are skipped,

the installer shall determine the requirement to engage a structural engineer to

determine the adequacy of the existing framing to support the additional loading

due to skipping battens.
