AbstractAffordable off-grid solar electricity to serve certain appliances, which consume less power, is highly desired in a household. The main objective of this presentation was to use fewer number of photovoltaic (PV) panels to power a household based on certain energy requirements and available insolation in Ekpoma, Nigeria. In order to achieve balance-of -system (BOS) components, appliances, which consume less voltage, were selected, with the conventional refrigerator and air conditioner replaced with thermoelectric types and with all the AC lights replaced with light emitting diodes (LED), thereby making it possible to use the direct current (DC) electricity from the system directly. To minimize usage of the inverter alternating current (AC) electricity, appliances with adaptors were selected. Formulae were presented for components specifications and to assess the energy payback time (EPBT) while the Photovoltaic Geographical Information System (PVGIS) online tool was used to evaluate the insolation and performance characteristics of the system. With clean energy availability driving the design, long term energy savings, with the energy payback time of 5 years for the system which is to last for 25 years outweigh short term design, material and installation cost. © Research India Publications.
