Complying with AS3000 requirements, Clause 1.71. at Micronisers install in 2014

In addition various building codes and the CEC best-practice guidelines apply.

Every solar PV installation where STCs are claimed requires an accredited CEC installer and designer to sign off that the install complies with these standards.

The standards clearly differentiate between clauses that are mandatory ‘shall’ and those that are recommended ‘should’.


There are a number of Australian standards that apply to Solar PV. Key of which is AS/NZS 5033 (applies only up to 240kWp systems). Generally the market has the impression that a solar PV installation will meet this standard and those listed below. This is rarely the case. Deviations can be as innocuous as loose terminals, poor signage, no expansion gaps, to severe, as undersized cables, hazardous installation methodologies resulting in fire risks, etc.

How does the customer assess compliance? Inspection? Inspection rarely captures all the key issues and even often misses the obvious ones. This is why iEnergytech does not seek inspectors who conveniently pass systems due to a comfortable relationship with installers or with iEnergytech but instead drive our installers to be that extra pair of eyes and step in the QC process. As such, we select our inspectors most carefully.

Some of the other standards that apply to Solar PV:

AS/NZS 1170.2 Wind Actions
