Africa Adds 2.4 GW of Solar Capacity in 2025 as Total Crosses 20 GW

Africa’s solar energy sector reached a major milestone in 2025, with the continent’s total operational solar capacity surpassing 20 gigawatts (GW) for the first time. The achievement underscores steady momentum in clean energy adoption, even as African markets continue to grapple with infrastructure gaps, financing constraints and grid reliability challenges.

According to the latest Solar Outlook report released by the Africa Solar Industry Association (AFSIA), the continent added approximately 2.4 GW of new solar photovoltaic (PV) capacity during 2025. While this figure is lower than the record 3.7 GW installed in 2024, industry experts say the underlying growth trajectory remains robust and supportive of Africa’s long-term energy transition.

China-driven supply boost

A key driver behind the expansion has been the continued inflow of solar equipment from China. For the first time, analysts used monthly Chinese export data to track solar shipments into Africa with greater precision. The findings show that solar exports from China to Africa rose by 17% in 2025, even as Chinese exports declined in many other global markets.

This divergence has positioned Africa as one of the world’s three fastest-growing solar markets since the pandemic, highlighting the continent’s increasing importance in global renewable energy demand.

Shifting national energy mixes

Rising imports are reshaping energy systems across the continent. Tunisia climbed sharply in continental solar rankings after ramping up solar panel imports, while Namibia and South Africa continue to lead when solar capacity is measured on a per-capita basis.

Overall, AFSIA estimates that around 32 African countries now have the technical potential to generate more than 10% of their electricity needs using imported solar panels. This places Africa in a distinctive position compared with other regions, where solar growth is often constrained by land availability, policy bottlenecks or grid limitations.

Storage becomes a game-changer

Battery Energy Storage Systems (BESS) are increasingly central to Africa’s solar expansion. Many countries operate with weak or fragmented power grids, making storage solutions essential for ensuring reliable electricity supply.

Between 2022 and 2025, battery prices fell sharply, allowing solar-plus-storage systems to become cost-competitive with grid electricity and diesel generation. This shift has been particularly important for commercial and industrial users, who require dependable, round-the-clock power to maintain operations.

Toward local manufacturing

Although Chinese technology continues to dominate Africa’s solar market, efforts to build local manufacturing capacity are gathering pace. Countries including Nigeria, South Africa and Ethiopia are seeing new solar manufacturing projects emerge.

As demand accelerates, analysts say it is becoming commercially viable to establish panel and component factories within Africa. Nigeria, in particular, is expected to play a leading role in the next growth phase and could soon become Africa’s largest solar market.

The trend points to a future in which Africa is not only a major consumer of solar technology, but also a regional manufacturing hub, strengthening energy security, creating jobs and supporting the continent’s broader green industrialisation ambitions.
