Abstract
The proliferation of off-grid communities in South Africa has necessitated a robust methodological framework to evaluate energy efficiency gains. A quasi-experimental design will be employed to compare pre- and post-intervention data from selected off-grid communities equipped with solar photovoltaic (PV) systems. The study will utilise a difference-in-differences approach with robust standard errors for statistical inference. This quasi-experimental design provides a rigorous methodological foundation for future studies aiming to enhance the sustainability of off-grid renewable energy systems in South Africa. The framework should be further validated through longitudinal data collection and expanded to include additional community settings and interventions. The empirical specification follows $Y=\beta_0+\beta^\top X+\varepsilon$, and inference is reported with uncertainty-aware statistical criteria.
