PV-ezRack SolarRoof Tilt Mount Penetrative Fixing System with ER-R-ECO Rail
for New Zealand
Gamcorp (Melbourne) Pty Ltd, being Structural Engineers within the meaning of Australian and New
Zealand Building Regulations, have carried out a structural design check of Clenergy PV-ezRack
SolarRoof Tilt Mount System installation with penetrative fixing within New Zealand. The design check
has been based on the information and test reports provided by Clenergy Australia.
This certificate is only valid for Clenergy PV-ezRack SolarRoof. The roof structure or the building
structure and PV panels shall be assessed separately and accordingly.
This certificate is only valid as a whole. Any information extracted from this certificate is not valid if
standing alone.
We find the Installation of Clenergy PV-ezRack SolarRoof Tilt Mount System for New Zealand use to be
structurally sufficient based on the following conditions:
●
Wind loads to AS/NZ1170.2:2021 Wind actions
●
Wind region NZ1 to NZ4
●
Wind terrain category 2 & 3
●
Importance level 2 ; Design life 25 years ; Wind average recurrence interval of 250 years
●
Maximum building height 20m
●
The assessed base PV panel dimensions are 2000mm x 1000mm
●
Tilt angle is measured to the roof surface
●
Maximum wind pressure is limited to 5kPa
●
Maximum Weight of the PV panels to be 15 kg/m
2
●
Rails to be ER-R-ECO
●
The base interface spacing are according to fixing into minimum 1.5BMT steel or minimum JD4
seasoned timber
●
Each PV panel to be installed using 2 rails minimum in all circumstances
●
No PV panel to be installed within 2xs from edges and ridge. “s” is the maximum gap between
the underside of the 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 of array frames to the roof, not the roof structure and
PV panels. It is the responsibility of the installer to adopt the most critical spacing.
●
The spacing shown in the interface tables shall be adjusted based on the assessment
and requirement of the roof structures.
●
If any of the above conditions cannot be met, the structural engineer must be notified
immediately.
