Africa is no longer a peripheral solar market; it is now the fastest-growing region for new installations, according to AFSIA, with momentum building around both utility-scale plants and village-level systems. Industry group GSC reports that the continent added about 4.5 G of new solar PV capacity in 2025, a 54% year-on-year jump that rivals growth rates in far older markets. That surge rests on a powerful driver: the World Bank estimates that off-grid solar delivered 55% of new electricity connections in sub-Saharan Africa between 2020 and 2022, turning energy access needs into a commercial boom.
Measuring the Boom
The scale of Africa’s solar expansion is now visible in hard numbers. The Core AFSIA outlook finds that operational solar capacity on the continent reached 23.4 G of installed power by the end of 2025, based on project-by-project tracking. At the same time, AFSIA’s import-adjusted estimates show roughly 63.9 G of solar capacity has been exported to Afr since 2017, highlighting a large pool of systems that may not yet appear in official generation statistics.
That difference between 23.4 G of operating plants and 63.9 G of imports helps explain why analysts say Africa is the world’s fastest-growing solar market rather than simply an emerging one. The Industry group GSC reports that Africa installed about 4.5 G of new solar PV in 2025, a 54% year-on-year rise that far outpaces mature markets where annual growth has cooled. Chinese customs data cited by the Financial Times reinforce that trend, indicating roughly 15 GW of solar modules were shipped to Africa in the year to June 2025, a volume that points to further capacity still working its way through project pipelines and distributed sales.
What Changed Now
The most striking shift is that Africa’s solar story is no longer confined to a few headline projects in a handful of countries. According to the World Bank, off-grid solar accounted for 55% of all new electricity connections in sub-Saharan Africa between 2020 and 2022, a period when many national grids struggled to keep up with population growth. That share reflects millions of households and businesses turning directly to solar kits, mini-grids and rooftop systems instead of waiting for grid extensions, and it underpins the rapid growth that AFSIA and GSC now describe.
Policy shifts since 2020 have also started to reshape the market, particularly in large economies like Nigeria and Egypt. The Canonical AFSIA report details how new incentives and clearer rules for independent power producers in Nigeria, along with supportive procurement frameworks in Egypt, have helped move projects from planning to construction. In South Africa, AFSIA’s country tables show utility-scale projects exceeding 1 GW of new capacity annually, indicating that a combination of power shortages and regulatory adjustments has opened space for private solar developers on a scale that did not exist a decade ago.
Key Drivers and Country Spotlights
The boom is not evenly spread, but a handful of markets are setting the pace. The Industry GSC identifies South Africa, Nigeria, Egypt and Algeria as the top four African solar markets in 2025, together accounting for a large share of the 4.5 G of new capacity. South Africa’s combination of large-scale plants and rapidly growing commercial and industrial systems contrasts with Nigeria’s focus on mini-grids and solar home systems that reach customers far from the national grid.
AFSIA’s policy segmentation highlights how Nigeria’s mini-grid sector has expanded under rules that allow private operators to serve rural communities with standardized tariffs, while Egypt and Algeria have leaned more on utility-scale tenders and state-led projects. Across these markets, Chinese manufacturers play an outsized role: the Major AP reporting on AFSIA’s findings notes that Chinese companies dominate module imports into Africa, a pattern reinforced by the Accountability Financial Times analysis of customs data. That supply has helped drive down costs, making it easier for developers and off-grid providers to scale.
Why It Matters for Energy Access
The stakes for energy access are enormous. The World Bank projects that off-grid solar could provide first-time electricity access to almost 400 million people globally by 2030, and its press release estimates that Africa alone will require about 21 billion dollars of investment in off-grid solar to meet demand. Because off-grid solar already delivered 55% of new connections in sub-Saharan Africa between 2020 and 2022, the continent is effectively the proving ground for whether that global projection can be met.
Economic effects are starting to follow the electrons. The Canonical AFSIA data show a growing band of mid-sized adopters where solar is creating jobs in installation, maintenance and local assembly, even if each individual market is smaller than the big four of South Africa, Nigeria, Egypt and Algeria. As imports climb toward the 63.9 G of capacity AFSIA has tracked into Afr since 2017, more of the value chain, from distribution networks to service companies, is being built on the continent rather than offshore.
Challenges and Uncertainties
Despite the rapid growth, the numbers still understate what is happening on the ground. The Industry GSC notes that distributed solar is undercounted in many official statistics, since small rooftop systems and informal imports can be hard to track. That gap helps explain why AFSIA’s 63.9 G import figure for Afr is so much higher than the 23.4 G of operational capacity identified in its Core Africa Solar Outlook, but it also makes planning for grids and backup capacity more complex.
Structural constraints could slow the boom if they are not addressed. The Accountability Financial Times reporting highlights weak transmission networks, slow permitting and currency risks that can delay or derail projects, even as module imports surge to around 15 GW in a single year. Financing beyond 2025 is another open question: while current pipelines are supported by a mix of development finance and private capital, AFSIA and other analysts have limited visibility on whether funding will keep pace with the multi-fold increase in investment the World Bank says Africa needs for off-grid solar alone.
Global Implications
Africa’s solar boom is reshaping expectations about where the next wave of renewable demand will come from. The Core AFSIA assessment that Africa is the world’s fastest-growing solar market, backed by 4.5 G of new installations in 2025 and a 54% annual growth rate reported by the Industry GSC, suggests that future global supply chains will need to serve Lagos and Nairobi as attentively as Berlin or Los Angeles. With roughly 63.9 G of solar capacity already exported to Afr since 2017, manufacturers, investors and project developers are treating the continent less as a frontier and more as a core growth region.
That shift could gradually diversify solar demand away from traditional centers in Europe and the United States, aligning with AFSIA’s outlook that sees Africa as a central pillar of global expansion. For that potential to be realized, however, policy will need to catch up with market reality: regulators will have to coordinate grid upgrades, clarify tariff structures and create financing frameworks that match the World Bank’s 21 billion dollar investment estimate for off-grid systems. If governments, financiers and communities can align around those needs, Africa’s current status as the fastest-growing solar market could evolve into a long-term anchor for the global energy transition.
