Abstract
This study assessed the adoption and performance of Solar Home Systems (SHS) in Gauteng Province, South Africa, with a focus on their effectiveness in lowering electricity costs and increasing consumer satisfaction using the expectancy-disconfirmation theory. Despite the growing reliance on SHS due to rising electricity prices and frequent power outages in South Africa, this study reveals a complex relationship between consumer expectations and SHS performance. The study explored two main objectives using a quantitative methodology that includes the distribution and analysis of questionnaires using R studio: the actual cost-effectiveness of SHS and the level of consumer satisfaction. The findings show a disparity between consumer expectations and SHS performance. Albeit there is general satisfaction with SHS, it does not correspond to the anticipated cost-saving benefits. This disparity emphasises the need for improved system performance and more precise consumer expectation management. The study concludes with recommendations for improving greater acceptance and satisfaction. This study adds to the discussion about renewable energy adoption, providing insights for policymakers, stakeholders, and consumers in areas facing similar challenges.
