Solar Water Heating Systems (SWH) are a renewable energy technology that heats cold water using the sun’s energy. The solar energy is absorbed by the panels or collectors, usually installed on top of the roof, and heats cold water.
Solar water heaters are a form of thermal heating, which relies on the direct energy emitted by the sun.
This is in contrast to other Solar Photovoltaic (PV) systems which convert the sun’s energy into electricity.
Solar Water Heating Systems are a good investment, especially for households with a monthly electricity bill exceeding R1200.

In 2008 rolling blackouts became part of the South African reality.
Compounding this, recent failures in the Eskom infrastructure and supply have added to an already critical electricity supply situation.
It is also emerging that even with new power stations in the pipeline, Eskom will be unable to overcome critical power supply constraints for at least the next 10-15 years, and the cost of power will have to increase dramatically in order for the country to be able to do so.
There are a few considerations when deciding whether your roof is suitable for a solar PV installation.
This is one of the reasons why it it important to have a solar energy professional provide a thorough assessment of your roof.
- Roof size
- Structural integrity of the roof
- Roof orientation and shade
- Correct angle depending on the latitude
The above factors must all be considered.
