Lack of access to modern forms of energy hampers efforts to reduce poverty. The provision of electricity to off-grid communities is therefore a long-standing developmental goal. Yet, many off-grid electrification projects neglect mid- and long-term operation and maintenance costs. When this is the case, electricity services are unlikely to be affordable to the communities that are the project's primary target. Here we show that, compared with diesel-powered electricity generation systems, solar photovoltaic systems are more affordable to no less than 36% of the unelectrified populations in East Asia, South Asia, and sub-Saharan Africa. We do so by developing geo-referenced estimates of affordability at a high level of resolution (1 km). The analysis illustrates the differences in affordability that may be found at the subnational level, which underscores that electrification investments should be informed by subnational data.
缺乏现代能源形式会阻碍减贫工作。因此，向离网社区提供电力是一个长期的发展目标。然而，许多离网电气化项目忽视了中期和长期的运营和维护成本。在这种情况下，电力服务不太可能为项目的主要目标群体所负担。在这里，我们表明，与柴油发电系统相比，太阳能光伏系统在东亚、南亚和撒哈拉以南非洲地区至少有 36%的无电人口负担得起。我们通过开发高分辨率（1 公里）的可负担性地理参考估计来实现这一点。该分析说明了在国家以下一级可能存在的可负担性差异，这强调了电气化投资应该以国家以下一级的数据为依据。
