Nigeria emerged as Africa’s second-largest solar installer in 2025 after recording a sharp rise in new capacity, according to the latest Africa Market Outlook for Solar Photovoltaic (PV) 2026–2029 report by the Global Solar Council.
The report disclosed that African countries installed 4,498 megawatts (MW) of solar PV capacity in 2025, representing a 54 percent year-on-year increase, about 2 GW more than in 2024. This makes 2025 the strongest year on record for solar expansion on the continent, surpassing the previous high set in 2023 when nearly 3.1 GW was deployed.
It said, “Nigeria achieved the ranking following an impressive year-on-year growth of 141 percent, driven largely by rapid expansion in distributed solar systems, high energy prices, policy concerns over potential import restrictions, and the rollout of the DARES programme.”
