INSTALLATION – SOLAR COLLECTORS
SOLAR COLLECTOR LOCATION
Consideration must be given to the position of the solar collectors in relation to the solar storage tank.
There are limitations on both the maximum length of the solar hot and solar cold pipes and the
maximum height between the solar storage tank and the solar collectors. Refer to
Location"
on page 14 and to
•
The solar collectors must be installed in a shade free position.
•
The solar collectors are to be installed facing toward
the equator (i.e. north facing in the southern
hemisphere and south facing in the northern
hemisphere). Where this orientation is not practical, a
system facing up to 45° from the equator will have its
efficiency reduced by approximately 4%.
•
Inclination
of
approximately equal to 90% of the local latitude angle.

latitudes of some Australian cities
page 22. Solar collectors may be installed at the roof
angle for simplicity of installation and appearance, but
must never be less than 10°. If the roof angle varies
by 15° from the correct angle, efficiency will be
reduced by 10%.
•
For an installation on a roof with a pitch less than 10°,
a Variable Pitch stand is required. Refer to your local
Solar Distributor for details.
•
For an installation at right angles to (across) the roof pitch, a Flat Roof stand and an Across Pitch
kit are both required. Refer to your local Solar Distributor for details.
•
For an installation opposite to (against) the roof pitch, a Flat Roof stand and an Against Pitch kit are
both required. Refer to your local Solar Distributor for details.
•
The collector kit is suitable for installations with an inclination of up to 45°. Where the solar
collectors are installed at inclinations greater than 45°, a With Pitch frame is necessary. Refer to
your local Solar Distributor for details.
•
The roof must be suitable to take the mass of the solar collectors. Each solar collector and its
fittings weighs approximately 46 kg when full of water.
•
The installation must comply with the requirements of AS/NZS 3500.4 and all local codes and
regulatory authority requirements.
•
Refer to the installation instructions supplied with the collector kit for details on the installation of
the solar collectors.
