1. INTRODUCTION
Thank you for choosing the SECT solar panel roof mounting system. Made from custom-
designed aluminium extrusions and components, SECT streamlined design and improved frame
strength greatly simplify solar panel installation. SECT is backed by a 10-year warranty and is
compliant with the AS/NZS 1170.2:2011/Amdt 2:2012 on wind actions and AS/NZS
16641.1:1997 on aluminium structures.
1.1. Overview
SECT solar PV arrays are assembled on the roof using channel (or rail), brackets and clamps.
The product is suitable for commercial format modules (approximately 2 m x 1 m) with frame
heights of 35 mm. Modules are held in one of three possible orientations:
10° tilt, back-to-back, so that each module shields the next from the wind, also called “east-west”
10° tilt, with each module facing in the same orientation, also called “north”
0° tilt, also called “flush”
1.2. Compliance and certification
SECT is supplied with a generic certification that suits most buildings, covering wind regions A,
B & C, terrain category 2 & 3. Custom certification is also available, e.g., for terrain category
1.5 or 1.0 (near open water), including an assessment of the site wind speed and the as-built
conditions of the roof sheet and roof frame. Certification is provided by Tensys Engineers. If the
roof is exposed to higher wind loads, such as near open water (Terrain Category 1) please
contact Schletter for guidance.
1.3. Orientation options
SECT can be installed in landscape ‘columns’ that proceed from gutter to roof ridge; or portrait
‘rows’ that proceed from side to side. The default method is in landscape ‘columns’, where the
fixing spacing is equal to the purlin spacing. Each column of modules is fixed to two channels
using edge and centre brackets that incline the modules at 10 degrees. Electrical cables can
run in the channels. Modules must have a 40 mm frame.
