Electric power from the grid is inadequate and unreliable in Nigeria, thus making it mandatory for operators of remote farming settlements to rely on private power generation equipment and usually in the form of a diesel engine generator. Concern for environmental pollution coupled with falling trends in the price of solar photovoltaic module, a major component in the standalone solar photovoltaic power plant, has considerably lowered the overall cost for the standalone solar power plant to the level of cost of power generation which is at parity with Power Holding Company of Nigeria (PHCN) private residential tariff and lower than the cost of power generation using diesel engine generator. A balancing parameter M, which characterizes the relative size of the battery storage in relation to the Photovoltaic power is defined and optimized for a minimum cost of power generation subject to an acceptable level of loss of load probability.
