- Description: This paper investigate the challenges faced by the occupants’ of low-income housing with their government installed solar water heaters in South Africa, Tshwane Metropolitan Municipality. The paper primarily investigates the challenges faced by the housing occupants since the solar heaters were installed in their low income houses. The data used in this paper were derived from both primary and secondary sources. The primary data was obtained through the survey method, while the secondary data was derived from the review of literature. The primary data for the study was collected through a structured questionnaire survey distributed to a sample of low-income households in a metropolitan municipality in South Africa. The household survey revealed that the low-income housing residents’ occupants’ faces challenges with regards to the leakage of the solar heaters and the noise from the heaters whenever the hot water taps are opened. The study gives an insightful view of the importance of using solar water heaters in energy conservation and lessening electricity financial constraints on the low-income households. The study adds to the knowledge on low income housing solar water heating in South Africa, with specific emphasis on the challenges faced by the occupants’. Further, findings from the study could be used for the development of sustainable structures in order to give access to energy and hot water to the poor and providing a better path to the improvement of life and empowerment through alternative energy usage in low-income households’ in South Africa.

- Description: M.Ing. (Electrical Engineering) , Abstract: In recent years the DSM residential program has extended itself to include subsidies for solar water heaters. This undertaking is primarily based on the fact that water heating contributes to about 30-50% of a households electricity demand. The National Solar Water Heater Program, encourages residential homeowners to install an approved SABS solar water heater by means of a rebate incentive. The Namibian national power utility NamPower is set to roll out a similar DSM initiative. Often for DSM initiatives, impacts need to be determined with a certain degree of accuracy to ensure the security of the various stakeholders involved. Measurement and Verification (M&V) is a practice where an independent body impartially determines and presents its findings of the impacts of a DSM initiative. The objective of this project looks to correlate the European (EN 12975-2) and American (ASHRAE 93) SWH standards to the South African (SANS 6211) SWH standard. The correlation will focus on finding a relationship between the performance coefficients of equations 9, 10 and 11 that are mentioned in chapter five. This interrelationship should allow PolySun to accurately simulate South African SWH systems that are not found in PolySun’s database. Providing an M&V entity, Utility or SWH consumer the option of simulating SWH systems found in South Africa in PolySun.

A qualitative study on solar energy use in South Africa

- Description: Abstract: Many South African citizens and residents are dependent on Eskom for electricity distribution. Its’ limited energy distribution and its’ ever increasing cost has taken its toll on the consumers. The citizens might be motivated to adopt solar energy technology to circumvent this problem. It is therefore imperative to establish, additional information that warrants investment in solar energy technology. Furthermore, it is imperative that consumers are presented with a database of information to the efficiency of solar power in households who have already implemented solar energy technology. It can therefore be suggested that there is paucity of research in South Africa in relation to challenges and benefits of using solar energy. In this regard a study was conducted in Gauteng province, in the city of Johannesburg, in South Africa to fill this gaps. The data was collected using semi-structured interviews. The target population for the current study were the suburban households which had solar photovoltaic (PV) and solar water heaters (SWHs) installation. A total number of 15 respondents were interviewed. The data was analysed using Tesch’s open coding approach. The findings suggest that these Johannesburg suburban households shared similar positive experiences and negative experiences from the use of solar energy systems. The findings suggest that the use of solar energy saved on electricity. However they experienced water leakage from their geysers. The findings from this qualitative research is of particular importance to the South African households who are considering an alternative solar energy supply.
