Abstract: This research study investigates the possibility of solar energy replacing other sources of energy such as thermal and hydro electric energy in domestic water heaters. Other than it being a renewable and cheaper alternative source of energy, solar energy has no documented polluting effect on its generation thus contributing positively to cleaner production for sustainable development, reduction in green house gas emission and potential cost savings. Economic comparative work on its use has been dealt with in water heating, and it has been found out that it can be utilized and result in appreciable power savings as well as effectively complementing existing supply sources. A number of energy management strategies have also been outlined to reinforce the solar initiative. Power deficit has been cited a challenge which need to be attended to. This work can be used as a resource for those considering an investment in solar water heating system option.
