Solar and battery adoption for households offers many benefits that motivate increased understanding of what drives investment. This paper uses microdata from a household survey in Kenya to investigate factors explaining investment in solar home systems, solar lighting systems, solar lanterns, and solar batteries. Key findings highlight the importance of assets for each investment type. Households are more likely to have a solar home system when they have bank or mobile money accounts, and when they own land with large values. Households are less likely to adopt solar systems when they are unable to afford grid connection, compared to households who are far away from electricity grids. Interaction analysis reveals that off-grid households without a mobile money account in key disadvantaged counties have lower solar home system adoption. A key policy implication is that support could be targeted to households with low levels of assets, in addition to existing support for suppliers.

家庭采用太阳能和电池有许多好处，可以促使人们加深对推动投资的因素的理解。本文使用来自肯尼亚家庭调查的微观数据来调查解释太阳能家庭系统、太阳能照明系统、太阳能灯和太阳能电池投资的因素。主要发现强调了资产对每种投资类型的重要性。如果家庭拥有银行或移动货币账户，并且拥有价值不菲的土地，则他们更有可能拥有家庭太阳能系统。与远离电网的家庭相比，无法负担电网连接费用的家庭不太可能采用太阳能系统。交互分析显示，重点贫困县没有移动货币账户的离网家庭太阳能家庭系统采用率较低。
