Eskom's subsidy on solar water heating

By reducing the amount of gas and electricity needed to heat water, solar water heaters save water heating costs. By using sunlight as opposed to combustible sources or fossil fuel-produced electricity, fewer pollutants are being infiltrated into the environment.

In order to reduce the growing demand for electricity, Eskom is embarking on energy efficiency and alternative energy programmes that promote energy savings. These projects take place on a large scale in order to alleviate system constraints.

The programme is structured around a repayment which reduces the selling price of a SABS approved solar water heating system .Home owners who purchase a solar water heating system from Eskom will receive a rebate. Deloittes are the facilitating auditors of the programme and customers will receive their rebate directly from them. 

Some of the conditions pertaining to the subsidy include:
• It must be a high-pressure system with pressure higher than 100kPa.
• The system must have a timer to optimise energy savings and regulate everyday usage. Alternatively, a load management device, i.e. a geyser buddy or ripple relay, must be present to control the usage in crisis situations.
• The system must be appropriate for the household and area in which it is installed, in terms of size, frost protection and water quality compatibility.
• It must have a comprehensive guarantee of at least five years.
• The system must have passed the South African Bureau of Standards (SABS) tests, and comply with the South African National Standards (SANS) for thermal and mechanical performance and safety.
• The supplier of the system must be registered with the SESSA (Sustainable Energy Society of South Africa) solar water heating division.
• The system must be installed by a registered installer and the customer will only be able to claim the rebate once facilitating auditors receive a final invoice from their supplier.
