Fast - lay the channel feet, channel, commercial roof brackets and then the PV modules. Cables can be laid in the channel and protected with a channel lid. Few parts, easy to lift and install.

Compliant - a signed engineering installation drawing is provided by Partridge Structural, who are registered structural engineers; and is supplied as part of the technical bulletin (download from the sidebar at right).

Durable - SunLock is 6000 series aluminium (predominantly 6106-T6) which has a 25+ year service life under Australian conditions, even without anodising.

Earthed - EarthLock washers and bonding terminals are fast to install and ensure that systems using transformerless (TL) inverters are properly earthed according to CEC guidelines.

Edge zones - the installation drawing includes spacing tables for edge zones. This is critical, as commercial clients often wish to make full use of available roof space.
