PV Array Frame Engineering Certification

Installation of Grace Solar GS-PR-01 Roof Mount Solar System on Tin and Tile Roof with GS-DR Rails

Gamcorp (Melbourne) Pty Ltd, being Structural Engineers within the meaning of Australian Building Regulations, have carried out a structural design check of Grace Solar GS-PR-01 Roof Mount Solar System installation on tin and tile roof within Australia. The design check is based on the information and test reports provided by Xiamen Grace Solar Technology Co.Ltd.

This certificate is only valid for the Grace Solar GS-PR-01 Roof Mount Solar System itself. The roof structure or the building structure and PV Panels shall be assessed separately and accordingly.This certificate is only valid when fixing into minimum JD4 seasoned timber and 1.9BMT steel.If the fixing condition is different from this condition, interface spacing shall be reviewed and validated.This certificate is only valid when the roof zone definition falls into D6 of AS1170.2-2011(R2016).This certificate is only valid as a whole. Any information extracted from this certificate is not valid if standing alone.

This certificate is based on the following test reports:

• GD Rail and Rail Splice Kit, by Xiamen Grace Solar Technology Co.Ltd, Report No. GS17121301, GS17121302, GS17121303, GS17121304, GS17121305, GS17121306, GS18051501, GS18051601, GS18051602, GS18051801, GS18051802 and GS18051803;

• Intern Clamp Kit, by Xiamen Grace Solar Technology Co.Ltd, Report No. GS17121904;• End Clamp Kit, by Xiamen Grace Solar Technology Co.Ltd, Report No. GS17121901,

GS17121902 and GS17121903;• Tin Interface Kit, by Xiamen Grace Solar Technology Co.Ltd, Report No. GS17121301,

GS17121303 and GS17121304;• Wind Uplift Testing on Grace Solar GS-PR-01 Roof Mounting System to MCS012, by Building

Research Establishment Ltd, Test No. 291-050, Dated 18th November 2013.

We find the Installation of Grace Solar GS-PR-01 Roof Mount Solar System on tin and tile roof for Australian use to be structurally sufficient based on the following conditions:

• Wind loads to AS/NZ1170.2:2011(R2016) Wind actions• Wind region A, B, C, D• Wind terrain category 2 & 3• Wind average recurrence interval of 200 years• Maximum building height 20m• The assessed PV Panel dimensions are 1960mm x 1000mm (72 Cells) and 1670 x

1000mm (60 Cells)• Panels to be flush-mounted to the roof surface• Weight of the PV panel and array frame to be 15 kg/m2• Rails to be GS-DR Rails minimum continuous spanning 3 spans• Refer to Note 1 for the assessed components and test reports provided• The spacings are determined based on fixings into minimum JD4 seasoned timber or

1.9BMT steel• Each PV Panel to be installed using 4 rails minimum for wind region D, wind terrain

category 2• Each PV Panel to be installed using 3 rails minimum for wind region D, wind terrain

category 3• Each PV Panel to be installed using 3 rails minimum for wind region C, wind terrain

category 2• Each PV Panel to be installed using 2 rails minimum for wind region C, wind terrain

category 3• Each PV Panel to be installed using 2 rails minimum for wind region A & B, wind

terrain category 2&3• No PV Panel to be installed within 2xs from edges and ridge. “s” is the maximum gap

between the underside of the PV Panel and the roof surface when installed on the roof (50mm≤s≤300mm)

• Installation of PV Panels to be done in accordance with the PV Panels installation manual

• The certification excludes assessment of roof structure and PV Panels

Refer to attached summary table for interface spacing (Unit mm)

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

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

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

• Standard Tile Interface is considered reaching its serviceability limit when 3° residual rotation of the middle plate is observed

• The spacing shown in the interface tables shall be adjusted based on the assessment and requirement of the roof structures

Construction is to be carried out strictly in accordance with the manufacturers instructions. This work was designed by John Zhang in accordance with the provisions of Australian Building Regulations and in accordance with sound, widely accepted engineering principles. This certification is only valid till 01/07/2020 and shall seek Gamcorp for re-validation after this date.
