Solar photovoltaics has tremendous potential to address current gaps in electricity access for resource-challenged settings, such as sub-Saharan Africa. However, a rapid surge in installations and future growth will lead to an increase in waste from panels and batteries, which needs to be tackled urgently. Innovative technical solutions and improved policies and standards are required to address end-of-life challenges for solar photovoltaics in sub-Saharan Africa.
