Off-grid communities in Tanzania rely on various renewable energy systems for electricity access, but their efficiency and scalability are not well understood. A mixed-method approach combining qualitative ethnographic observations with quantitative analysis of panel data. The study employs econometric techniques, including ordinary least squares (OLS) regression for estimating yield improvements. Panel data analysis revealed that the adoption rate of solar home systems was significantly higher in regions with more accessible infrastructure, indicating a clear relationship between system accessibility and uptake. The methodological framework developed in this study provides valuable insights into enhancing off-grid energy solutions for Tanzania's rural communities. Further research should focus on scaling up successful models and addressing socio-economic barriers to wider adoption. off-grid systems, yield improvement, panel data analysis, Tanzania The empirical specification follows Y=₀+^ X+, and inference is reported with uncertainty-aware statistical criteria.
