| dc.description.abstract | According to the energy agency’s study on electricity costs, a 37% increase in global energy demand is expected by 2040. The trans-Saharan regions of Africa are experiencing rising energy demand as a result of the rapid urbanization and accompanying significant economic and population expansion. These needs include those for electricity, air conditioning, and hot water. Increased geopolitical, economic, and environmental hazards result from this circumstance. When renewable energy policies are in place, their primary goals are to reduce reliance on fossil fuels, manage energy consumption, and meet the
socioeconomic needs of the general population. Therefore, this study will investigate the economic performance parameters, including cash inflows from energy savings, maintenance costs, net cash inflows, net present value, and payback times, as well as energy savings, when using the already installed solar water heating system at NHE 2114 House in Windhoek, Namibia. Assuming a life expectancy of 25 years for SWH, the system conserved an average of 700 kW of energy in a full year and had a 15-years payback period, allowing the user to profit for almost 10 years. | en_US |
