Abstract Energy access is crucial for human well-being and poverty reduction. In sub-Saharan Africa, the failure of grid systems to provide electricity access to last mile users has led to the rapid scale up of off-grid solutions. The authors examine synergies and tradeoffs between solar off-grid solutions and the Sustainable Development Goals (SDGs) in Rwanda which as a nation has successfully implemented innovative solar off-grid systems at scale. This paper is the first to map the relationship between energy and the 169 Targets of the 2030 Agenda in a specific country and sector context by operationalising the framework developed in Fuso Nerini et al. (2018). By doing so, this paper demonstrates the need for context-specific rapid assessment tools to monitor and improve energy access. The paper identifies synergies between 80 (47%) of the SDG targets and off-grid solar systems in Rwanda, thus demonstrating the wideranging benefits and value added through the inclusion of the off-grid solar energy sector in the electrification strategy. The paper demonstrates how mainstreaming off-grid policies and prioritising investment in the off-grid sector can realise human development and well-being, build physical and social infrastructures, and achieve sustainable management of environmental resources.
