The adoption of off-grid community systems in South Africa's rural areas has shown promise for enhancing agricultural productivity. However, methodological gaps remain in understanding their impact on crop yield. A mixed-method approach was employed, including quantitative econometric modelling using panel data techniques. The study utilised robust standard errors and confidence intervals for statistical inference. Panel-data estimation revealed significant improvements in yield by up to 15% when off-grid systems were integrated with sustainable agricultural practices. The integration of off-grid community systems with conventional farming methods has the potential to significantly boost crop yields, particularly among resource-limited communities in South Africa. Policy makers should consider incentivizing the adoption of these systems and supporting infrastructure development for rural areas. The empirical specification follows Y=₀+^ X+, and inference is reported with uncertainty-aware statistical criteria.
