Code-Compliant Planning and Installation Guide V1.0 - Complying with AS/NZS1170.2-2011 AMDT 2-2016
- Planning -
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 some trees or isolated obstructions, terrains in developing outer urban areas
with scattered houses, or larger acreage developments with more than two and less than 10 buildings per hectare.
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-size obstructions per hectare, e.g.
suburban housing, light industrial estates or dense forests.
Terrain Category 4 (TC4) – Terrain with numerous larger, high (10m to 30m tall) and closely-spaced constructions
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.
Determine the Roof Type
This document provides sufficient information for SADL bracket A1 installation on Kingspan KS1000 RW Trapezoidal
Roof Panel having different insulation core thickness (40-120 mm) with an exterior sheet of a minimum 0.42 mm thick. If
your installation is on a different roof type, please contact Clenergy to obtain a project-specific engineering certificate
to support your installation.
Note: Bracket installation is allowed on the full rib of Kingspan roof only. Installation on lap joints must be avoided.
Verify Atmospheric Corrosivity Zone of Installation Site
Please refer to “AS 4312-2008 Atmospheric Corrosivity Zones in Australia” or consult local construction businesses to
verify the corrosivity category of the installation site to determine appropriate products and interface spacing.
Note: Clenergy provided screws for Tin interfaces are suitable for up to C3 corrosive environments only.
Determine the Height of the Installation Site
This document provides sufficient information for the PV-ezRack® SolarRoof™ system installation up to heights of
30 meters. If your installation site is more than 30 meters high please contact Clenergy to obtain a project-specific
engineering certificate to support your installation.
Determine Roof slope
SADL bracket A1 installation on Kingspan KS1000 RW Trapezoidal Roof is certified for roof slopes up to 10°. Please verify
that the Installation site roof slope is between 0° and 10°.
Determine the Installation Area of Roof
Please refer to the generic notes 25, 28 and 29 of the Certification Letter to determine the installation area based
on building height, length, and width. Please be aware at certain building conditions there is an Exclusion Zone for
flush installation, which is the minimum distance between PV solar panel and roof edge of "2 x s", where "s" is the gap
between the underside of the panel and the roof surface.
Determine the Maximum Rail Support Spacing
Please refer to the Certification Letter and Interface Spacing Table. If a project-specific Certification Letter has been
provided, please refer to the support spacing in this letter.
