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 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 . In order to optimise irradiation. Heater units should never
be laid flat.
•
Avoid any shade, especially between 10am and 4pm. Shade reduces system
efficiency.
Preferably, solar water heaters 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.
