Solar photovoltaic system design is mainly predetermined by the system requirement, environmental governing policies, standard and awareness. These and others, are measured ingredients considered in this sustainable design of the stand-alone solar household project in Wukari. In this project, the PV design is mainly influence by the number and types of appliances used. A system capable of supplying energy for a typical house in Wukari was design and components sizing were approved. The key structure’s gears such as the photovoltaic panels, battery, charge controller and inverter are stated, taking the insulation level of ten (10) average hours of sunlight per day with an estimate for a total cost of the system. The total electrical supply to the load appliances of 5190W in the building will be from the PV source. To power these appliances, 4 modules with the power rating of 220W under a standard test condition (STC)of 1000W/㎡ and 25°C temperature, 4 batteries of (24V-200Ah) in the battery bank with system battery capacity of 848Ah, one charge controller of 50A-24V is selected and a 2KVA inverter is required. The aim of this work is to size each component of a PV system based on the numbers, types, and wattage of the appliances and design a suitable Off-grid/Stand-alone PV system that can generate reliable 24 hours power supply within the residential household eliminate grid dependency.
