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
“Solar Storage Tank Location” on
page 21 and to “Pipe Lengths” on page 33.
• 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 the solar collectors
should be approximately equal to
90% of the local latitude angle. The
latitudes of some Australian cities
are listed on page 32. 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.
