Abstract One of the pressing challenges to economic development in sub-Saharan Africa (SSA) is access to electrical power. In Nigeria, there is a large gap in electricity access between rural and urban areas; only about 40% have access in rural areas as compared to almost 60% in urban areas. A potential solution is the use of off-grid solar electricity to meet their needs. This article seeks to assess the tradeoffs involved in using off-grid solar electricity from the perspective of Nigerian households. Given their generally low income levels, the research focuses on the lower end of the market for off-grid solar electricity: solar chargers. It uses choice experiments to measure households' preferences for solar electricity by exploring attributes rural households are looking for in solar chargers. The relationship between households' preferences and off-grid solar electricity was analyzed using a random parameter logit model. Findings indicate that confidence in the quality of the product was the most important variable, and that respondents associated higher priced solar chargers with higher quality. These findings suggest that energy companies making off-grid electricity technology could consider offering warrantees for high-quality products in order to build consumers' trust.

使用选择实验来了解离网太阳能电力属性的偏好：尼日利亚家庭的案例

摘要 撒哈拉以南非洲 (SSA) 经济发展面临的紧迫挑战之一是获得电力。在尼日利亚，农村和城市地区之间的电力供应存在很大差距；农村地区只有大约 40% 的人可以使用，而城市地区则接近 60%。一个潜在的解决方案是使用离网太阳能来满足他们的需求。本文旨在从尼日利亚家庭的角度评估使用离网太阳能电力所涉及的权衡。鉴于他们的收入水平普遍较低，该研究的重点是离网太阳能电力市场的低端：太阳能充电器。它通过探索农村家庭在太阳能充电器中寻找的属性，使用选择实验来衡量家庭对太阳能电力的偏好。家庭之间的关系 使用随机参数 logit 模型分析了偏好和离网太阳能电力。调查结果表明，对产品质量的信心是最重要的变量，受访者认为价格较高的太阳能充电器质量较高。这些发现表明，制造离网电力技术的能源公司可以考虑为高质量产品提供保修，以建立消费者的信任。
