It is a requirement that all array frames for photovoltaic modules are compliant to AS/NZS 1170.2 Wind Loading Standards to indicate the array will withstand local wind conditions in your location.
All systems eligible for government rebates require a Complinace letter from a registered Australian Engineer to be included with the instruction manual supplied to the customer.
Although only small areas of Australia are affected by cyclones, it was decided that Alzone racking components should be designed to withstand cyclonic conditions.
All Solar Module Mounting Kits available for roof installations are certified to withstand Cyclonic Region D wind velocity, the highest wind rating in Australia.
The difference between a kit provided for a cyclone area and one for a standard area is the distance that is required between the “Feet” that attach the module to the roof. Solar Module Kits for cyclone prone areas will have a greater number of Feet than kits supplied for non cyclone areas.
Engineering Compliance for Wind Loading is based on whole system and parts used in the system.
If using parts from different Manufacturers / Suppliers you will void any compliance offered from either Manufacturer or Supplier, and you will need to contract a suitably qualified registered Australian Engineer.
