The feasibility of building integrated Photovoltaic systems for single residential buildings in the Western Cape, South Africa

Abstract

Purpose This study aims to determine the feasibility of making use of Building Integrated Photovoltaic (BIPV) Systems in single residential buildings in the Western Cape with the aim of applying it in this region. Design/methodology/approach Information required for the case studies and qualitative research was collected from up-to-date product specifications from suppliers and specialists, journals of research by others, and from interviews with PV specialists and representatives from the national utility provider. The case studies were conducted to measure the generating capacity of BIPV systems, determine system requirements for residential application, and to compare BIPV system costs with conventional electricity costs. The qualitative research was undertaken to identify polices that could be used to promote the usage of BIPV systems in South Africa. Findings In spite of global PV developments and high industry growth rates, the financial feasibility of the usage BIPV systems in South Africa remains poor. Policies implemented by the National Energy Regulator (NERSA) for the promotion of clean energy generation seem to be inadequate and will have to be reconsidered. Value The study aims to promote the application of BIPV systems, which will have beneficial results for both the South African economy and the environment.
