Thank you for choosing the PoleLock solar
photovoltaic (PV) module pole-mounted framing
system, part of the SunLock family of solar framing
products. PoleLock is suitable for a wide variety of
commercial and remote installations.
PoleLock is backed by a 10-year warranty and
compliant with the Australian / New Zealand
Standard on Wind Actions (AS/NZS1170.2.2011).
PoleLock can support one or two modules on one
pole. More modules can be supported by joining
several PoleLock frames together in a line.

AS/NZS1170.2.2011 provides guidance on determining the
wind pressures applicable to your PoleLock installation site,
taking in local terrain and topography. Sufficient guidance is
given in this document, but you may wish to procure a copy
of these standards if your company installs Australia wide.
If you are unsure about complying with standards, or if you
are not qualified to install this product, please consult either
SunLock or a registered structural engineer.
Footings
The footings for PoleLock have been designed by a
registered structural engineer, and are appropriate for
natural ground, not topsoil, fill, or disturbed ground.
Check that the soil at the install location is appropriate for
this footing design. If it is not appropriate, you will need to
get the footing checked by a registered structural engineer.
Handling
The materials used in the PoleLock frame can have sharp
corners or edges. Wear personal protective equipment such
as safety glasses, hearing protection and gloves during
cutting and handling.

aluminium cutting blade can be used to trim the SunLock
channel to the desired length)
Hand Drill (An electric hand drill for drilling holes in
the base of the mounting post)
Drill Bits (A 6mm & 13mm drill bit is required to drill
holes in the mounting post)
Anti-galling Lubricant (if required, anti-
galling lubricant may be required to aid
in the tightening of stainless steel
fasteners)
Ring Spanner (A M10 ring spanner for
tightening supplied fasteners)
Hex Key (A 6mm hex key / driver bit is
required to secure the SunLock channel
to the channel feet)
Gloves (For handling SunLock framing, as
aluminium can develop sharp corners)

The PoleLock range of frames can support either one or
two modules of various sizes in a portrait orientation. If
required, multiple PoleLock frames can be installed on one
site to provide increased power.
PoleLock has been designed to accommodate the
following panels:
(675mm x 1500mm) ~ 120W - 160W panels
(808mm x 1580mm) ~ 170W - 210W panels
(1000mm x 1680mm) ~ 215W - 250W panels
(1046mm x1556mm) ~ 327W panels
And any panel size up to 2150mm x 1200mm

Note: PoleLock is certified for use with the following
mounting post:
• 90 DN DuraGal pole (101.6mm outer diameter, 4mm
wall thickness)
• 250 MPa
• 3200mm pole length
Installation
1. Ensure the location is suitable for pole mounted solar
installation.
2. Ensure no building / trees are shading the modules.
3. Dig holes in undisturbed, natural ground with a soil
friction angle of 22 degrees or greater.
1 Panel Frame:
450mm diameter pier, 1200mm deep
2 Panel Frame:
450mm diameter pier, 1400mm deep
600mm diameter pier, 1200mm deep
4. Drill a hole in the end of the mounting pole, insert an
M12 bolt/rod and fasten
5. Place the galvanised pole into the hole ensuring that
the pole sits on a 100mm base of gravel. Fill with the
required amount of 25 MPa concrete. Ensure the
pole is oriented plumb.

The PoleLock frame consists of two parallel SunLock
channels connected to a central beam through two channel
brackets. This frame is connected to a pivot assembly which
in turn is mounted on the top of a mounting post.
Pivot Assembly
1. Insert each U-bolt through the corresponding holes
in the supporting plate and pivot bracket and loosely
attach the washers and nuts. Slip the assembly over
the top of the mounting pole and tighten. Ensure the
pivot flanges are pointing in the intended northerly
direction.
2. Take the second pivot bracket and slide the pivot
bolt through the mating holes ensuring that both
brackets rotate freely. Loosely tighten all fasteners.
Frame Assembly
1. Take the central beam and fasten the channel
brackets to the ends.
2. Centre and attach the SunLock channel to the
channel brackets by fastening the supplied M8
socket head cap screws.

Total Assembly
1. Place the frame assembly on top of the pivot
assembly and tighten all fasteners.
2. Loosely attach the required PV module end-clamps
to the end of the SunLock channels.
3. Loosely attach the module mid-clamps in the centre
of the SunLock channels (2 panel only).
4. Place the solar panel on top of the frame and fasten
down the end clamps, ensuring that the clamps
securely hold down the panel.
5. (2 Panel Only) Attach and fasten the supplied mid
clamps to the other side of the panel.
6. (2 Panel Only) Repeat steps 4 and 5 for the second
panel.
7. Ensure all clamps are sufficiently fastened to prevent
panels dislodging from the frame.
8. Set the desired inclination angle of the solar array by
placing the 30mm M10 bolts through the two sets of
holes in the pivot bracket.
9. Securely tighten all fasteners and ensure that the
assembly is rigid.

If required, multiple PoleLock frames can be installed on one
site to provide increased power. The PoleLock frames can be
assembled in series to accommodate 3 to 6 panels in wind
region A or B.
The multiple frame installation consists of multiple single or
double panel frames arranged in series, with the channel
ends joined using SunLock channel joiners. Channels can
either be cut to appropriate lengths, using a circular saw with
an aluminium cutting blade, or longer lengths of channel can
be custom ordered.
The number of poles required for installations in wind region A
& B, Mt = 1.0, can be found in the table below.
The chart below is only applicable for the 4 panel size:
(675mm x 1500mm) , (808mm x 1580mm) , (1000mm x
1680mm) , (1046mm x1556mm). Any other size, please check
the Polelock general certificate.
