Optimal energy cost and economic analysis of a residential grid-interactive solar PV system- case of eThekwini municipality in South Africa

In this paper, an optimal energy control of a 3 kW residential grid-interactive solar PV system is presented. A typical two-bedroom household within the eThekwini municipality in the city of Durban, South Africa, is considered. The aim is to assess the potential of energy cost saving and cost effectiveness the system can achieve under the new residential feed-in tariff (FIT), referred to as residential embedded generation tariff.
