A homegrown expandable minigrid solution that researchers at the University of the Witwatersrand (Wits) have been developing, testing and refining for several years has now been fully commercialised to be marketed and sold locally and throughout Africa as the Peco Powerbrick. The innovation is based on the pioneering work of academics and students at the university’s School of Electrical and Information Engineering who, under the direction of Professor Willie Cronje, have been working on an expandable and affordable offgrid solution for low-income African households since 2014.
