Africa’s official solar power data undercounts the continent’s rapid renewable expansion, with a new report revealing that distributed solar installations—driven by households and businesses—account for half the growth unrecorded by national statistics.
Official solar power data across Africa is missing nearly half of the continent’s renewable energy boom, according to a report by Ember and the African Tech Futures Lab. The analysis, which uses Chinese customs data and on-the-ground installation rates, estimates that Africa added 17 gigawatts of solar capacity in 2026—an increase of 45% from 2025 and the third consecutive record year. This figure far exceeds the International Energy Agency’s (IEA) 6.2GW and the International Renewable Energy Agency’s (IRENA) 4.6GW, highlighting a stark disconnect between official records and real-world deployment.
The Hidden Growth: Distributed Solar Outpaces Official Records
The undercount stems from the rapid rise of distributed solar—rooftop panels and small-scale systems—primarily installed by households and businesses rather than utility-scale projects. These installations, which account for over half of Africa’s solar capacity since 2023, are often untracked or unregulated, leaving governments without the data needed to plan effectively. The problem is a lot of this isn’t being recognised,
said Dave Jones, chief analyst at Ember. National reporting of solar is quite poor… one of the reasons for that is because so much comes from distributed solar.
Joel Nana, research director at African Tech Futures Lab and project manager at Sustainable Energy Africa, emphasized the scale of the gap. Even in countries with robust data like South Africa, [the issue] is the visibility of this behind-the-meter data. It’s not appearing in any record, and when it appears, it vastly underestimates the true scale of deployment out there,
he said. Only 36 of Africa’s 54 countries publish any official solar capacity data, and just 14 report figures for 2025. The report found that even these 14 countries underestimate the surge, with many failing to account for the decentralized nature of solar growth.
The reliance on Chinese solar exports underscores the gap. Chinese customs data, cross-referenced with installation rates in other markets, reveals that Africa’s solar boom is driven by a flood of panels arriving from the world’s largest manufacturer. There was this excellent dataset released by Ember last year on the imports from China,
Nana noted. The one question that has been lingering on everyone’s mind is how much of that actually gets converted into actual installations.
The answer, according to the report, is that a significant portion does—yet national planners remain unaware.
Chaos in the Grid: Policy Lagging Behind the Energy Transition
The misalignment between data and reality is creating what Nana calls a chaotic and disruptive
transition. Across Africa, distributed energy resources are rapidly expanding, and in many cases overtaking grid capacity,
he said. This transition is chaotic and disruptive, and far from the orderly model planned in national strategies.
The African Union’s (AU) Continental Power Systems Masterplan, which forecasts 23GW of solar by 2040, has already been surpassed by the past three years’ installations alone. Grid planners risk overbuilding fossil fuel capacity or underinvesting in the infrastructure needed to integrate solar, according to the report.
South Africa’s IRP is one of the few national plans that explicitly accounts for distributed generation, but even it faces challenges. The choice now is whether these distributed assets remain a parallel power system that compensates for grid failure or are integrated in ways that unleash a wider range of benefits,
Nana said. The report warns that without better data and planning, the continent’s solar potential could be squandered.
The economic implications are stark. In countries with unreliable grids, diesel generators have long been a backup, but rising fuel prices—exacerbated by the Iran war—are making solar more attractive. Generating the same electricity from a diesel generator as from a solar panel would cost as much in diesel, every three months, as the solar panel itself,
the report states. This shift is accelerating, yet policymakers are still operating with outdated figures.
A Call for Data Transparency and Policy Reform
The report urges African governments to improve data collection and transparency. Countries are already leapfrogging into faster, more secure, cleaner energy growth, and the governments that get ahead of it stand to gain all the benefits,
Jones said. However, without accurate data, it’s difficult to assess progress or allocate resources effectively. The lack of quarterly reporting in most countries means that planners are running blind to the true scale of solar deployment, the authors argue.
Yet, the report emphasizes that the responsibility lies with individual nations. The problem is a lot of this isn’t being recognised, Jones reiterated, stressing that international agencies can only report what governments provide.
What Comes Next: A Continent at a Crossroads
As Africa’s solar boom continues, the next critical step is for governments to update their data systems and integrate distributed energy into national plans. The report warns that planning is already behind reality, with the AU’s 2040 target already exceeded. Without action, the continent risks missing out on the full benefits of its renewable potential.
The coming months will test whether African leaders can adapt to this rapid shift. Will they prioritize data transparency and grid modernization, or continue relying on outdated metrics? The answer will shape not only the continent’s energy future but also its economic and environmental trajectory. As Nana put it, The choice now is whether these distributed assets remain a parallel power system that compensates for grid failure or are integrated in ways that unleash a wider range of benefits.
