description Traditional AC grids have been well established in the Power field of industry from generation, transmission to distribution. This is a direct effect of the war of the currents in the 19th century which saw the AC current being victorious over DC due to a significant flaw of which it was economically unviable to convert voltage and it would also too complex to construct. There is an increasing sense of urgency for the Earth to start finding alternative way to generate electrical energy. The traditional method of generating electricity has been under pressure to be removed due to the emissions of greenhouse gases as a result of burning oil, coal and natural gas to generate electricity. Furthermore, [1] has predicted that mankind will exhaust the reserves which are technologically possible to access for these natural resources required to generate electricity by 2081. As such it becomes more urgent to find alternative ways to generate electricity. Fortunately, in the recent years’ technology has developed with renewable energy technology emerging. Photovoltaic(PV) panels have better efficiencies and become viable to generate and cope with small demands.
