==Costs==

The cost will vary widely around Africa, depending on the size of the system and whether the materials used have to be imported. Import taxes and taxes on business sometimes add to the expense. Governments could help promote solar water heating by reducing taxes for businesses selling solar water heaters. In South Africa in 2005, a 70 litre solar water heating system cost R3000 (US$455). Larger systems with electric back-up cost up to R10000 (US$1520).
