Installation

Tools Required
It is essential that the installation is completed by an accredited plumber who has been
trained in solar water installations and has completed an installation training course on this
type of solar system.
In order to complete the installation successfully the following tools are recommended:

System Location
The location of the solar water heater should be on an even surface facing true north. A variation
of 20 degrees either side of true north will have a negligible effect on the overall performance.
The collector must be in full sun, free from shadows, between the hours of 9am to 4pm
throughout all the seasons.
The tilt angle recommended for the collector is latitude plus 15 degrees. Increasing the tilt angle
will improve the winter performance while decreasing the tilt angle will increase summer
performance. The lower the latitude, the more critical the tilt angle will be to the overall system
performance.
Cloud cover will affect performance, if cloud is predominantly in the mornings, then try to face
the solar collector more west of north, and if cloud cover is in the afternoon, then facing the
collector more east of north will assist the performance. The Solar input as indicated on page 11
will provide an indication of the worst performing months of the year. In winter rainfall areas it
is recommended that the tilt angle is increased to improve winter performance.
Tips on finding True North
Satellite dishes point to PAS7/10. This is positioned 68 degrees East of North.
Some GPS systems will have a compass. Please confirm the accuracy of this before using it as
they will sometimes require movement to determine direction.
Use of a sundial type compass with a vertical shadow and a time of day can also be used to find
True North.
