3 Solar thermal
3.1 Introduction
The sun supplies every day a multiple of the required world wide daily energy demand
to the earth. The energy of the sun is available in various forms such as:
- direct, diffuse and reflected solar radiation
- wind
- waves
- the ground and in other forms.
Solar thermal systems convert the energy incident from the sun on an absorber surface
into sensible heat in form of hot water. Depending on the temperature required and
achieved, this hot water can be used for a whole range of applications as summarised in
Figure 1.
