The provision of adequate and sustainable power supply to the country’s citizens has been a mirage since the 80’s when the nation neglected signals to improve its power generation capacity. The rapid population growth and increase in industrial activities necessitate the injection of solar photovoltaic technology into the nation’s energy mix. This paper therefore is an attempt to design a standalone solar photovoltaic system for residential application. in this study, direct current (DC) appliances (lighting, fan, DVD player, radio) and alternative current (AC) appliances (television, refrigerator, and blender) were considered. The total load power of these appliances is 1981w. The array to load ratio determined as well as the daily watt -hour load shows that the use of hybrid system in this design is not recommended. To power these appliances, 64 modules with power rating 13052.8W under standard test condition (STC), 56 batteries in the battery bank with system battery capacity of 4900 Ah and one charge controller are required. Therefore, for sustainability, reliability and accessibility of power, the use of stand-alone solar photovoltaic technology is recommended.
