4. SITING
Correct siting is critical for the effective operating of a solar water heater, the following
being important guidelines:-
Orientate the principal axis of the units in a North/South direction, with the collector
l
facing the equator. This orientation is important to maximise sun exposure on the
collector as it tracks on its East /West axis throughout the day.
Tilt at approx 15 . This is important as it optimises irradiation and also assists in the
l
thermosyphon process. Heater units should never be laid flat.
Avoid any shade, especially between 10am and 4pm. Shade hugely reduces system
l
efficiency.
Preferably, solar panels should be installed on roofs where solar irradiation is highest and
they are also less exposed to damage. If this is not possible a protected ground sitting is
acceptable.
