What you need to know about changes to solar hot water installation standards

29 June 2016

An updated version of AS/NZS 3500.4 was published late last year with particular impact on the installation requirements for solar hot water systems.

So what has changed?

Clause 6.5.1.2 within the standard now specifies that collectors shall be installed so they face no more than 45° East or West of true North.

Section 6.3.13 also includes updates to the installation conditions of fixing straps for tiled roofs. When using fixing straps to restrain collectors on tiled roofs, the straps shall pass beneath the tiles and be fixed directly to the rafters or trusses with at least three screws 40mm longer per fixing strap.

So what happens where the roof orientation is not within the allowable orientations?

Solar mounting frames can be considered for alternative roof orientations by installing with pitch, against pitch or cross pitch. Thermann solar mounting frames are adaptable to suit these types of conditions. For help in understanding when ‘with pitch’, ‘against pitch’ or ‘cross pitch’ installations should be considered, refer to the below diagram.

This information is intended as a guide only and to provide a brief overview of the changes to the Standard. For more information on these changes, please always ensure you refer to the relevant local regulations and ensure all installations are carried out in accordance to the specifications and recommendations of AS/NZS3500.4:2015 and other relevant standards and building codes.
