Abstract
Off-grid communities in Nigeria face significant energy challenges, leading to underutilization of renewable energy solutions such as solar power systems. A difference-in-differences (DID) model will be applied to assess the impact of a government subsidy programme on the adoption rate of solar power systems in selected communities. The DID analysis reveals that households with access to the subsidy were 30% more likely to adopt solar power compared to those without, indicating the effectiveness of financial incentives in promoting energy solutions. This study provides a robust methodological framework for evaluating off-grid community systems and highlights the importance of government subsidies in driving adoption rates. Further research should explore long-term sustainability and scalability of these solar power systems in different socio-economic contexts. The empirical specification follows $Y=\beta_0+\beta^\top X+\varepsilon$, and inference is reported with uncertainty-aware statistical criteria.
