Installations of solar power in Africa jumped 54% in 2025, new data shows, marking the fastest annual growth on record, driven by governments and development agencies deploying utility-scale projects and households and businesses putting in rooftop and commercial systems. 

A new report published by the Global Solar Council (GSC), a nonprofit trade body, shows that Africa installed around 4.5 gigawatts (GW) of new solar photovoltaic (PV) capacity last year, topping the previous record set in 2023 and outperforming initial predictions.

Utility-scale projects accounted for around 56% of reported installations in Africa in 2025, while distributed solar made up an estimated 44%. However, the report notes that rooftop, commercial and distributed capacity – which refers to small-scale solar generation usually situated near where the electricity is used – is significantly under-reported because of limited data.

The GSC said recent soaring solar equipment imports and deployment trends point to a broader, more diversified market serving two types of energy transition at the same time: government-led solar power projects and privately financed business and residential installations.

    For instance, the continent imported 18.2 GW of solar panels in 2025, yet under a medium installation scenario, countries are projected to build just 14.3 GW of mainly utility-scale capacity in 2026 and 2027.

    Over the past four years, only about 15% of solar equipment imports have been used in large utility-scale installations, pointing to rapid growth in rooftop, commercial and captive systems that are not fully reflected in official figures, the report said.

    It also highlighted the need for greater and faster investment in battery storage, grids and power system flexibility, to improve reliability of supply and support rising industrial and commercial energy demand.

    “Solar + storage is the hope of Africa,” said Sonia Dunlop, GSC’s chief executive officer, in a statement on the report. “This is the technology that can bring energy access, sustainable development, green growth and resilience to natural disasters and extreme weather,” she added.

    Medium-sized markets expand

    Large, established markets for solar power continue to lead the pack in Africa, with the top 10 solar markets accounting for around 90% of new capacity additions in 2025, led by South Africa with 1.6 GW, followed by Nigeria at 803 megawatts (MW), Egypt at 500 MW and Algeria at 400 MW.

    However, solar deployment is spreading across a wider group of African countries, the report noted, with a clear shift away from reliance on a handful of early adopters. Several mid-sized and emerging markets made significant gains last year, including Morocco, Zambia, Tunisia, Botswana, Ghana and Chad. 

    The report found that eight African countries each installed more than 100 MW of solar capacity in 2025, double the number recorded in 2024, underscoring the pace at which new markets are expanding.

    “Africa’s solar boom is remarkable, showing just how quickly we can deploy clean energy when technology, demand and ambition come together,” said Zoisa North-Bond, CEO of Octopus Energy Generation. “Solar is becoming more accessible, more efficient, and – most importantly – cheaper every year. It’s encouraging to see this potential being realised across Africa faster than ever before.”

    Finance for off-grid falling behind

    Despite the rapid growth of distributed solar, financing models have not kept pace. While rooftop solar and microgrids are scaling rapidly, around four-fifths of clean energy finance on the continent still comes from public and development sources geared towards large, government-led projects, the GSC report said.

    Private investment in clean energy increased from about $17 billion in 2019 to nearly $40 billion in 2024, but most of this funding is not aimed at supporting smaller solar systems used by homes and businesses. 

    These smaller projects need modest loans, shorter repayment periods and financing in local currency, but with current offerings not structured this way, many households and companies struggle to access affordable funding for solar, despite strong demand and falling technology costs.

    Last week, leaders from major solar mini-grid players – including the largest operator Husk Power Systems – said up to $46 billion will be needed by 2030 to meet the electrification targets of 29 African countries under the World Bank-backed Mission 300 initiative. According to Bloomberg, the total would comprise $28 billion in debt, $14 billion in equity and $4.6 billion in grants and subsidies.

    Investment needed to unleash growth

    The GSC’s medium-term outlook suggests Africa could install over 33 GW of solar capacity by 2029  – more than six times the amount added in 2025 – as markets expand across more countries. 

    However, the group warned that the misalignment between funding and market needs risks slowing deployment, raising system costs and limiting the economic value of solar. 

    If, on the other hand, reforms align finance, planning and regulation with market realities, solar and storage can deliver not only clean power, but reliability, economic productivity and long-term energy security, the GSC said.

    Solar paired with battery storage is critical to delivering affordable, reliable power at the scale required to meet energy demand in Africa, which is expected to grow eight-fold by 2050, said Damilola Ogunbiyi, special representative of the UN Secretary-General for Sustainable Energy for All.

    However, she added, “more must be done to attract clean energy investment, with mechanisms to spur public, private and philanthropic financing.”

    China’s Shark Finning Could Lead to US Seafood Sanctions

    A formal petition to the U.S. government calls for sanctions on Chinese seafood imports as it highlights China’s loophole-ridden illegal shark fin trade.

    For migrant workers trapped onboard Chinese distant water fishing fleets, cutting the fins off sharks as they writhe violently on rusted decks in the Indian Ocean isn’t accidental. It’s an intentional and lucrative act that marks the start of a bloody half-a-billion-dollar offshore supply chain, tacitly supported by Beijing yet covertly concealed from port inspectors globally.

    New data shows rich nations likely missed 2025 goal to double adaptation finance

    Published

    on

    New data on international climate finance for 2023 and 2024 suggests that wealthy countries are highly unlikely to have met their pledge to double funding for adaptation in developing nations to around $40 billion a year by 2025 amid cuts to their overseas aid budgets.

    At the COP26 climate summit in Glasgow in 2021, all countries agreed to “urge” developed nations to at least double their funding for adaptation in developing countries from 2019 levels of around $20 billion by 2025. Funding for adaptation has lagged behind money to help reduce emissions and remains the dark spot even as the data showed overall climate finance rose to a record $136.7 billion in 2024.

    A United Nations Environment Programme report warned last year that wealthy nations were likely to miss the adaptation finance target and the data released on Thursday by the Organisation for Economic Co-operation and Development (OECD) shows that in 2024 adaptation finance was just under $35 billion.

    The OECD, an intergovernmental policy forum for wealthy countries, said the increase between 2022 and 2024 was “modest”, adding that meeting the doubling target would require “strong growth” of close to 20% in 2025.

    More cuts likely

    The OECD’s figures do not go up to 2025, but several nations announced cuts to climate finance last year. The most notable was the abandonment of US pledges to international climate funds by the new Trump administration but the UK, France, Germany and other wealthy European countries also pared back their contributions.

    Joe Thwaites, international finance director at the Natural Resources Defense Council, said developed countries were “not on track” to meet the adaptation funding goal.

    Power Shift Africa director Mohamed Adow said adaptation finance is needed to expand flood defences, drought-resistant crops, early warning systems and resilient health services as the world warms, bringing more extreme weather and rising seas. “When that money fails to arrive, people lose homes, harvests and livelihoods – and in the worst cases, their lives,” he warned.

    Imane Saidi, a senior researcher at the North Africa-based Imal Initiative, called the $35 billion in adaptation finance in 2024 “a drop in the ocean”, considering that the United Nations estimates the annual adaptation needs of developing countries at between $215 billion and $387 billion.

      If confirmed, a failure to meet the goal is likely to further strain relations between developed and developing countries within the UN climate process. A previous pledge to provide $100 billion a year of total climate finance by 2020 was only met two years late, a failure labelled “dismal” by the UAE’s COP28 President Sultan Al Jaber and many other Global South diplomats.

      Missing that goal would also raise doubts about donor governments’ commitment to meeting their new post-2025 adaptation finance goal. At COP30 last year, governments agreed to urge developed countries to triple adaptation finance – without defining the baseline – by 2035.

      African and other developing countries have pointed to lack of funding as a key flaw in ongoing attempts to set indicators to measure progress on adapting to climate change.

      Speaking to climate ministers from around the world in Copenhagen on Wednesday, Turkish COP31 President Murat Kurum stressed the importance of climate finance. “It is easy to say we support global climate action,” he said, “but promises must be kept.”

      He said the COP31 Presidency will use the new Global Implementation Accelerator and recommendations in the Baku-to-Belem roadmap, published last year, to scale up climate finance – and will hold donors accountable for their collective finance goals.

      He noted that developed countries should this year submit their first reports showing how they will deliver their “fair share” of the new broader finance goal set at COP29 in 2024, to deliver $300 billion a year in climate finance by 2035. They are due to report on this once every two years.

      Broader climate finance

      The OECD data shows that the overall amount of climate finance – including funding for emissions cuts – provided by developed countries grew fast in 2023 before declining in 2024. In contrast, the amount of private finance developed countries say they “mobilised” increased in both 2023 and 2024, pushing the top-line figure to a record high.

      While the OECD does not say which countries provided what amounts, data from the ODI Global think-tank suggests that the 2024 cuts to bilateral climate finance were spread broadly among wealthy nations.

      Thwaites of NRDC welcomed the fact that overall climate finance provided and mobilised by developed countries exceeded $130 billion in both 2023 and 2024. He said that this was “well above earlier projections” and “shows that when rich countries work together, they can over-achieve on climate finance goals”.

      But Sehr Raheja, programme officer at the Delhi-based Centre for Science and Environment, said these figures are “modest” when set against the new $300-billion goal.

      “While the headline total figure of climate finance remains alright,” she said, “declining bilateral climate spending raises important questions about the predictability of high-quality, concessional public finance, which has consistently been a key demand of the Global South.”

      She also lamented that loans continue to dominate public climate finance and that mobilised private finance is concentrated in middle-income countries and on emissions-reduction measures rather than adaptation projects. “Private capital continues to follow bankability rather than climate vulnerability or need,” she added.

      Ritu Bharadwaj, climate finance and resilience researcher at the International Institute for Environment and Development, said the figures painted an outdated picture as climate finance has since declined as rich countries shrink their overseas aid budgets and increase spending on defence.

      Last month, the OECD published figures showing that international aid – which includes climate finance – fell by nearly a quarter in 2025. The US was responsible for three-quarters of this decline. The OECD projects a further decline in 2026.

      With Thursday’s climate finance report, the OECD is “publishing a victory lap for 2023 and 2024 at almost the same moment its own aid statistics show the funding base eroding underneath it,” Bharadwaj said.
