I. Introduction
The national electric grid of South Africa has gone through significant adjustments over the past decade. The government has undertaken the allegiance to invest in alternative solutions to conventional coal energy production technology by exploring renewable energy sources in particular solar, wind and hydro. In point of fact, the unyielding commitment to alleviate the release of greenhouse gases, has led to an enormous growth of D2PGS in South Africa. As a result of their excellent location for this application, the provinces leading in the photovoltaic power generation include Northern Cape, Western Cape and Free State [1]. The present photovoltaic power generation capacity in South Africa is about 1,274MW [2]. Furthermore, determinations have been indicated by the Integrated Resource Plan (IRP) on solar PV energy that expects a generation capacity of 8,500MW by 2030 [3].
