Electricity is one of the main requirements for sustainable development and the improvement of living standards for different nations. Remote areas in Botswana depend in the use of fossil fuels e.g., petrol, diesel and natural gas to produce electricity. However, the villagers encounter high fuel price from buying fossil fuels. On the other side, combustion of fuels creates air pollution that contributes to global warming which is accountable for climate change and disastrous effects. This is a study that explores replacing the fossil fuel used by a village shop in Majwanaadipitse, Botswana (22 ̊ 6 ̍ 50 ̋ S, 26 ̊ 53̍ 0 ̋ E) with an off- grid PV system. This was done by designing, sizing, estimating the contribution to pollution by the fossil fuels and costing an off-grid solar PV system. The estimated energy requirement of a village shop was found to be 7.97 kWh/day. The design and sizing of the PV system equipment’s depended on the estimated load. The proposed off-grid PV system required 5 PV modules each rated 330 W, 5 batteries each rated 100Ah, a charge controller and an inverter. The system capacity of an off-grid PV system to be installed was 1.6kW௣. The emitted pollution into the atmosphere to be avoided was found to be 2882 Kg of carbon dioxide per year. The payback period of the PV system was estimated to be 2 years. The NPV was also found to be favorable, showing that it is a profitable investment with a cost of P653 880. The study revealed that an off-grid PV electricity is technically and economically feasible for electrifying a shop compared to the use of fossil fuels.
