Wind and Climate Considerations
If panels are to be installed on a roof then the following should be observed to limit wind
uplift potential.
1)
Installed panels
should lay flat close to the roofs surface.
It is recommend the air
gap distance between the bottom of the installed collector and the valley points of
the roof corrugations should be no greater than approximately 40mm.
2)
Panels should have adequate clearance from roof edges.
3)
Panels on roofs MUST NOT be mounted on tilt frames
.
Why?
The average air gap distance between the mounted collector and roof structure has a
strong influence on wind loadings. Furthermore due to roof edge turbulence effects wind
loadings are highest near roof edges.
Panels installed above the roof structure with 50mm or greater underneath air gaps experience
much higher wind loadings and are now subject to the Australian wind loading standard
AS/NZD 1170.2.
It is the responsibility of the installer to consider wind loading factors, see
“wind proofing”
section below.
If the installation site is within strong wind speed areas then the extra
stainless steel guide line must be installed across each row with the in-between panel
anchor points.
Do not assume supplied components are sufficient.
