Off-grid communities in South Africa face challenges in accessing reliable energy sources essential for agricultural productivity. A randomized field trial was conducted among 100 off-grid households, with baseline data collected on system characteristics and performance metrics. Randomization ensured balanced groups for comparison. System reliability varied by up to 25% across different household configurations, indicating significant variability influenced by infrastructure quality and maintenance practices. The trial highlighted the importance of robust design in off-grid systems, with specific findings on system configuration impacts. Investment strategies should prioritise high-reliability components for improved agricultural productivity. The empirical specification follows Y=₀+^ X+, and inference is reported with uncertainty-aware statistical criteria.
