A sector report on off-grid solar in Sub-Saharan Africa, outlining the access gap, affordability barriers, and how PayGo and blended finance can unlock a $20 billion opportunity.

This sector report assesses off‑grid solar as a path to expand electricity access in Sub‑Saharan Africa. It notes 571 million people lack power, with 4 countries holding the largest share.

Off‑grid solar is the most cost‑effective option for about 368 million people by 2030. Affordability is a critical constraint, with cash prices out of reach for most unelectrified households. The report highlights PayGo financing, now a significant share of solar home system sales, and sets out a blended public and private funding requirement of about $20 billion.
