Africa is experiencing a solar revolution. In 2026, the continent’s total installed solar capacity will surpass 20 GW, driven by falling battery costs and urgent energy demand.

But which nations lead the pack? We break down the top 10 African countries by total installed solar capacity (Megawatts) , highlighting the giants, the dark horses, and the off-grid innovators.
1. South Africa – 8,900 MW
The Undisputed King
South Africa remains Africa’s solar powerhouse. The Renewable Energy Independent Power Producer Procurement Programme (REIPPPP) has unleashed a flood of utility-scale projects. Crucially, private commercial and industrial (C&I) solar now dwarfs public procurement, as mines and factories install massive rooftop arrays to escape crippling load-shedding.
2. Egypt – 1,800 MW
The Desert Giant
Egypt leverages its vast, sun-baked deserts. The Benban Solar Park in Aswan (one of the world’s largest) drives most of this capacity. In 2026, Egypt is aggressively adding solar to free up natural gas for export, making it a critical East African leader.
3. Morocco – 1,150 MW
The Concentrated Solar Power (CSP) Pioneer
While famous for the Noor Ouarzazate complex (which stores energy as heat), Morocco is now rapidly adding photovoltaic (PV) panels. The country aims to reach 52% renewables by 2030, with solar providing the backbone of its grid.
4. Nigeria – 1,100 MW
The Off-Grid Giant
Nigeria’s official grid capacity seems modest for Africa’s largest economy. However, this figure hides a boom in mini-grids and solar home systems. Companies like Husk Power and Rensource have deployed thousands of decentralized systems, making solar the primary power source for millions of off-grid Nigerians.

5. Algeria – 850 MW
The Rapid Riser
Algeria launched a massive 5,000 MW solar tender in 2023, and the first tranches are now online. The government is pivoting from natural gas to solar to meet domestic demand, freeing more gas for European exports.
6. Ghana – 180 MW
The West African Steady Hand
Though smaller in capacity, Ghana boasts one of the continent’s most stable renewable energy policies. The Nzema solar project and numerous rooftop installations provide reliable power to complement its hydro dams.
7. Kenya – 175 MW
The Geothermal-Solar Hybrid
Kenya is famous for its Rift Valley geothermal, but solar is surging. The 55 MW Garissa Solar Plant is East Africa’s largest, and private C&I solar is exploding in Nairobi’s industrial zone, helping businesses stabilize power costs.
8. Namibia – 140 MW
The High-Yield Champion
Namibia’s exceptionally high solar irradiation (among the best in the world) makes every installed MW count. The country leads in solar penetration (over 17% of grid power), and new projects are supplying its booming green hydrogen industry.

9. Senegal – 125 MW
The Regional Pioneer
Senegal’s 2026 capacity is anchored by the 60 MW Ten Merina plant (West Africa’s first large-scale solar-battery hybrid). With support from the World Bank’s Scaling Solar program, Senegal is proving that solar + storage can replace heavy fuel oil.
10. Zambia – 110 MW
The Copper Belt Solar Hub
Zambia leverages solar to reduce its reliance on hydropower (which suffers from droughts). The Bangweulu and Ngonye solar plants have proven so successful that utility-scale expansion is accelerating rapidly across the country.
🏆 Honorable Mentions (High Solar Percentage)

If we ranked by percentage of electricity, small nations would dominate:
· Central African Republic (37%)
· Chad (36%)
· Somalia (32%)
These countries have leapfrogged traditional grids entirely, using solar mini-grids to electrify rural areas.
📈 Why These Rankings Will Change by 2027
1. Battery Storage Costs are falling 15% annually. Expect Nigeria and South Africa to add hundreds of MW of hybrid solar-battery plants.
2. Green Hydrogen projects in Mauritania, Namibia, and Egypt will drive massive new solar buildouts (5,000 MW+ each).
3. China’s overproduction of solar panels keeps global prices low, accelerating African deployment.
💡 Key Takeaways for Investors & Policymakers
· Don’t look only at grid-connected MW. In Nigeria and DRC, off-grid solar serves more people than the utility.
· Solar + storage is now cheaper than diesel across 90% of Africa. The economics have already flipped.
· The leaders of 2026 (South Africa, Egypt, Morocco) will remain giants, but 2027–2028 will see Sudan, Ethiopia, and Angola surge into the top 10.
