The prospect of rapid growth in solar photovoltaic (PV) installations across South Africa will create opportunities for the localisation of supply chains and for domestic manufacturing, a new study commissioned by the South African Photovoltaic Industry Association (SAPVIA) has confirmed. However, the report also underlines the importance of economies of scale and stable and predictable demand for facilitating the investments needed for the manufacture of components such as PV modules, inverters, mounting structures and cables.
