Off-grid communities in Tanzania often rely on unreliable energy sources, leading to increased risks of power outages and health hazards. The study employs a two-arm randomized controlled trial design where participants are randomly assigned to either an intervention group using solar-powered energy solutions or a control group. Data on risk reduction is collected and analysed over a 12-month period. The randomized field trial methodology provides robust evidence on the effectiveness of off-grid systems in Tanzania. Further research should explore cost-effectiveness and scalability of these solutions across different socio-economic contexts in Tanzania. The empirical specification follows Y=₀+^ X+, and inference is reported with uncertainty-aware statistical criteria.
