This section provides general advice
on wind loadings. If you have any doubt about your wind loadings please contact
21.1
Ultimate Peak Wind Loadings per Panel
The following Tables specify the ultimate peak uplift any single panel can experience in a 1 in 500 year extreme
storm or cyclone event according to Australian Standard 1170.2 - 2011 (Amend 2 Dec 2012). These tables assume:
1)
Panels are mounted on (touching) the roof structure - or no more that 20mm off the roof surface
2)
Panels are situated away from a roof edge or corner
3)
Installation is on a first story roof
4)
Shortest side length of the building is more than twice the average building height (i.e. flat building)
If your installation falls outside of these assumptions please contact

As an example if you are in
Wind Region B
and
Terrain Category 3
and have a
roof
pitch 12.5˚
then any single panel
in your collector system could experience momentary peak uplifts of
~120Kg
per panel. You should make sure your
