South Africa’s abundant coal resources have historically kept electricity costs low, encouraging widespread use of electric appliances, especially electric geysers, which account for 25% to 40% of household electricity bills. However, rising energy prices and increasing strain on the national grid are eroding this advantage. Solar Water Heaters (SWHs) offer a cost-effective alternative, particularly given the country’s high solar radiation levels. Despite this, there is limited research on the cost-benefit of SWHs in rural areas. This study examines their use in Thulamela Municipality, Limpopo Province, and finds that SWHs are a viable and sustainable solution for household energy needs. They reduce electricity consumption, require minimal maintenance, and have long lifespans. Although the initial cost of SWHs is higher than electrical geysers, they offer short payback periods, especially as electricity tariffs increase. The study recommends that the government actively promote solar energy by providing financial support and increasing public awareness to encourage wider adoption.
