Abstract

Figures from the Global Solar Council (GSC) suggest that Africa added 4.5GW of new solar PV capacity in 2025, a record for annual additions and a 54% increase over the previous year.
This is the headline takeaway from the GSC’s’ Africa Market Outlook for Solar PV: 2026-2029’, published this week. The report notes that the majority of Africa’s solar deployment is concentrated in a few leading markets—South Africa (1.6GW of new operational capacity), Nigeria (803MW) and Egypt (500MW) lead the top ten in terms of capacity additions, which accounted for 90% of all new capacity added in Africa in 2025—but that “mid-sized and emerging markets” added “substantial new capacity” in 2025.
