As a result of the destruction of Darwin in 1974, by Cyclone Tracey, the Northern Territory has some of the tightest building regulations in the world. Since the 21st of October 2010 it has been mandatory for all Solar PV installation within the Northern Territories building control zone to have a building permit and engineering certification.

Where required we have tested products to meet the requirements in accordance with the NT Building Act. Our internal processes and document controllers handle the engineering process from start to finish including facilitatating the Building Permit, Engineering Certification and updated Occupancy Permit.

There is currently only 1 panel approved under the Deemed to Comply standards, the Auxin panel (DTC/M/539). This DTC has been written in such a way that only a roof of rare dimensions will satisfy its provisions.
