==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).

==Field experiences==

====India====

The Ministry of New and Renewable Energy is responsible for maintaining the standards of solar water heating in India and they provide approval for a number of efficiency test centres around the country such as the School Of Energy Studies , University of Pune.

These efficiency centres conduct solar water heater tests at regular intervals that conform to the specifications set by the Bureau of Indian Standards (BIS).

====South Africa====

Eskom launched a rebate program for solar geysers in 2008. To qualify for a rebate, all systems need to undergo testing carried out by the South African Bureau of Standards (SABS).

Each one tested by the SABS receives a rating (Q-factor), which indicates the kilowatt-hours (kWh) of electricity it's expected to save on a typical day and the units ability to produce hot water.
