I. Introduction
The population with access to electricity in Sub-Saharan Africa in 2019 was only 47.9%, with South Africa as an exception to this as 94.3% of the population had access to electricity [1]. In 2018, 89.6% of South Africa's rural population had electricity access compared to 92.1% of the urban population [2]. One reason for the lower percentage of electrification in rural South Africa is lack of access to utility grid where grid extension may not be economically viable. This is because rural areas have low incomes, low energy and the households are scattered [3]. A viable electrification option for such rural areas is development of stand-alone renewable electricity generation by hybridizing the locally available biomass with a more stable energy source such as a diesel generator.
