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 the maximum length of the solar
hot and solar cold pipes between the solar storage tank and the solar
collectors. Refer to “Solar Storage Tank Location” on page 26 and to “Pipe
Lengths” on page 37.
• 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 37. Solar collectors may be
installed at the roof angle for simplicity
of installation and appearance, but must
never be flat. 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 30°.
Where the solar collectors are installed at inclinations greater than 30°, 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 40 kg when full of water.
