INTRODUCTION
SunLock commercial solar panel tilt frames are a simple, fast framing system for typical Australian steel framed commercial roofs. The solar PV modules are mounted in landscape at either 10° or 15° above the roof sheet, using brackets on SunLock channel. The channel forms a conduit for cabling(Example at the end of this article). Refer to the Commercial Installation Manual (available for download from www.sunlock.com.au/support-document-1) for detailed information and certification.

PARTS
SunLock commercial roof brackets are supplied as a kit (one front bracket and one rear bracket), including channel nuts for fixing to the SunLock channel. 10° and 15° versions include fixed end-clamps to hold the module to the bracket, while 15° versions is assembled by adding a 5º extension to the 10º. The rear brackets could be mounted together for placing the panels in an east-west orientation.
For a standard two-channel installation, two kits are required to fix each module. The brackets suit modules with a width of ~ 1 m, such as a typical 72 cell module using polycrystalline cells.
The brackets are extruded from 6005-T5 mill-finish aluminium and have a 25+ year service life under Australian conditions.
PV modules can be earthed by the built in earthing pins on each front and rear bracket. The mill-finish aluminium components form a conductive path, and an earth cable can be attached to the end of each SunLock channel.

GUIDE TO USE
Install SunLock channel
Install SunLock channel v3 “north-south”, using two channels per column of modules. Refer to the installation manual for details. Fix a channel foot to each steel purlin using a standard roofing screw (an EPDM washer included for water sealing). Slot the SunLock channel into the feet and lock it in using the cap screws on the feet. An upper frame can be added using channel feet plus a channel nut between the two layers of channel. If roof clamps are used, use a SLCF3 to connect the roof clamp to the channel.
If necessary, use a sub-frame
Installing of sub-frame could refer to this technical bulletin
Install front brackets
After determining the appropriate row spacing for the site, install all the front brackets on the channel. It may be helpful to prepare a spacing jig (cut a length of channel to length) to ensure uniform spacing across the array.
Install modules onto front brackets
Lay the modules on the Front brackets.
Install rear brackets
Lift up the rear of the module , slide the rear brackets underneath the module and connect them. The clamps are all spring loaded so you just need to push the rear bracket and tighten all the M8 screws on the front and rear leg.
Install cabling
Run cables in the channel, and cover using the channel lid. Optionally, other extra sections of channel can be used as cable conduit.
