While South Africa is deemed one of the countries with highest irradiation levels, it still utilises coal as its primary energy source due to abundance. Due world-wide drive towards carbon neutrality, residential, commercial, agricultural, and industrial consumers are considering small-scale embedded generation systems. The National Rationalised Specifications 097-2-3 document specifies scale capacity a consumer allowed install. However, specifications do not yet make required provisions for addition storage. effective collective management grouped systems could provide high level security increase percentage renewable in total mix. Potential challenges come into play when stochastic nature photovoltaic effect on storage dispersion load profiles residential units typically present low-voltage network.
