Off-grid communities in Senegal face challenges in accessing electricity, necessitating innovative solutions. A multilevel regression analysis was conducted to assess the impact of various socioeconomic variables on system efficiency across different geographical regions in Senegal. The analysis revealed a significant positive correlation (p < 0.05) between per capita income and the level of electrification, indicating that higher-income communities achieved better performance with their off-grid systems. Multilevel regression analysis provided robust insights into cost-effectiveness metrics for off-grid community systems in Senegal. Further research should focus on implementing energy-efficient technologies and improving access to finance for low-income households. The empirical specification follows $Y=\beta_0+\beta^\top X+\varepsilon$, and inference is reported with uncertainty-aware statistical criteria.
