Lighting the way to profitable recharging: a techno-economic analysis of workplace solar-powered electric vehicle chargers in Potchefstroom, South Africa

Abstract

The increased number of electric vehicles (EVs) in South Africa necessitates increased charging infrastructure and reliable electricity supply. Efficient electricity generation and EV charging strategies are required to avoid increasing electrical grid strain. Deploying solar-photovoltaic EV charging stations can reduce electrical grid strain whilst increasing the number of available chargers. By analysing the energy requirement for recharging EVs, as well as the cost associated with a solar-powered charging system, a system configuration that allows for profitable operation can be determined. This approach utilises HOMER GRID software to minimise cost while ensuring system effectiveness. The results of this study can provide valuable information to policymakers, industry stakeholders and investors, enabling them to make informed decisions on the feasibility, development and implementation of workplace charging infrastructure. This research contributes to the integration of EVs and sustainable renewable energy generation by offering a practical solution for workplace EV charging infrastructure.
