東アフリカのケニア、ルワンダ、タンザニアにおけるオフグリッドソーラーホームシステムの導入が家計の福祉と教育に与える影響を検証。日射量の変動を操作変数として用いた分析により、太陽光システムの導入が灯油支出の削減、照明の質の向上、子供の学習時間の増加をもたらすことを示した。
English
This study examines the impacts of off-grid solar home systems on household welfare and education in East Africa. Using an instrumental-variable approach with solar irradiance data, it finds that adoption reduces kerosene expenditure, improves lighting quality, and increases children's study hours, contributing to energy-inclusive human development.

In the global GX context
This paper provides empirical evidence on the welfare benefits of off-grid solar, relevant for global energy transition discussions and development finance. It underscores the importance of financing models and maintenance pathways for inclusive energy access, complementing ISSB/TCFD frameworks that focus on corporate disclosure rather than household-level impacts.
👥 読者別の含意
🔬研究者:Provides robust causal evidence on off-grid solar's welfare effects, useful for researchers in energy economics and development.
🏛政策担当者:Highlights the role of financing and maintenance in off-grid solar success, informing development policy and international cooperation.
📄 Abstract（原文）
Off-grid solar home systems have become a central element of energy access strategies in East Africa, particularly in Kenya, Rwanda, and Tanzania, where pay-as-you-go models have expanded rapidly. This paper examines how household adoption of solar home systems affects welfare and education outcomes, using nationally representative surveys, regional solar irradiance data, and education indicators from UNESCO. The analysis applies an instrumental-variable strategy that exploits exogenous variation in solar irradiance to address adoption endogeneity. Results show that higher irradiance significantly increases the likelihood of adopting solar home systems, which in turn reduces kerosene expenditures, improves lighting quality, and supports longer study hours for children. Welfare gains are evident through higher household savings, improved perceptions of wellbeing, and reduced energy insecurity. Education outcomes benefit through increased evening study time and reduced school absenteeism during rainy months, when grid reliability declines. These findings align with emerging evidence from East Africa that off-grid solar can strengthen inclusive energy transitions and contribute to human development when supported by favourable financing models, consumer protection, and long-term system maintenance pathways. The results offer policy guidance for regional initiatives aiming to expand sustainable, affordable, and reliable household energy access.
