Solar power in Africa

Africa is often referred to as the "Sun continent", as it is the continent where the Sun's influence is the greatest. According to the "World Sunshine Map", Africa receives many more hours of bright sunshine during the course of the year than any other continent of the Earth and many of the sunniest countries on the planet are in Africa. Despite its immense solar power potential, before 2024, Africa was largely behind other continents when it comes to building up grid and off-grid solar capacity, in part due to a lack of investment. However, more recently the decline in the price of solar units from China has led to a significant increase in imports of solar panels. A study by Ember found that solar panel imports to Africa surged by more than 60% between June 2024 and June 2025. During that year more than 25 countries imported more than 100 MW of solar panels. Following the 2026 Strait of Hormuz crisis, Reuters reported a further 15 countries reported record solar imports of more than $400 million in the first quarter, compared with $650 million for all of 2025.

Solar potential

The whole continent has a long duration of sunshine, and excluding the large areas of tropical rainforests (the Guinean Forests of West Africa and much of the Congo Basin), as the desert and savannah regions of Africa represent Earth's largest cloud-free area. Africa is dominated by clear skies even beyond deserts (ex: Sahara, Namib, Kalahari). However, the regions located along the equator are considerably cloudier than the tropics and subtropics. The eastern Sahara/northeastern Africa is particularly noted for its world sunshine records. The area experiences some of the greatest mean annual duration of bright sunshine, with the sun shining brightly for approximately 4,300 hours a year, equivalent to 97% of the possible total. This region also has the highest mean annual values of solar radiation (the maximum recorded being over 220 kcal/cm2). The combination of all these geographical and climatic factors is the cause of the large solar potential of Africa. The number of days of sunlight allows the potential of bringing solar power to much of Africa without large scale grid infrastructure. The distribution of solar resources across Africa is fairly uniform, with more than 85% of the continent's landscape receiving a global solar horizontal irradiation at or over 2,000 kWh/(m2 year). Also, the theoretical reserves of Africa's solar energy are estimated at 60,000,000 TWh/year, which accounts for almost 40% of the global total, thus making Africa the most sun-rich continent in the world.

Pay-as-you-go solar The pay-as-you-go solar system offers credit to poorer customers in rural Africa, thereby allowing them to invest in infrastructure for their homes. The most consistent approach to tackling this huge obstacle to development has come with the off-grid pay-as-you-go solar power model, now called PayGo, which in some countries such as Malawi, a company called Yellow is electrifying the population faster than grid electricity. The PayGo system leverages the technology of mobile money to receive payments from customers, allowing them to pay from rural locations without a smartphone or access to the internet.

Solar photovoltaics

Declining solar equipment costs were expected to significantly increase solar installations in Africa with an industry projection forecasting that the continent's annual PV market would expand to 2.2 GW by 2018. Future installations for harvesting solar energy in Africa are expected to be located within the equatorial and subequatorial climate zones. These installations are generally expected to be concentrated in western Central Africa, primarily near the equator and extending to approximately the 8th or 9th parallel north and south. This is because these regions experience persistent cloud cover and only intermittent bright sunshine. Therefore, countries that entirely lie in this wet-humid zone such as the Republic of the Congo, Equatorial Guinea, Gabon, Rwanda, Uganda, Burundi, Liberia, Sierra Leone and Senegal are among the least favorable in solar power of all the continent. By contrast, most other African countries more than 2,700 hours of bright sunshine over atleast part of their territory. Many perpetually sunny African nations like Egypt, Libya, Algeria, Niger, Sudan, South Africa, Botswana and Namibia have significant potential for a large scale solar energy tranistion, owing to their extensive land area and high levels of sunshine and to the decreasing price of the necessary hardware By 2023, South Africa had installed 500 MW in concentrated solar power, 2286 MW in utility scale solar, and 4400 MW in rooftop solar. Several 75 MW PV plants and two CSP plants at 100 MW each were the largest in the country and among the largest in Africa. South Africa has announced a plan to install a minigrid on Robben Island; adding PV and battery storage is predicted to reduce diesel usage by half. A 55 MW photovoltaic power plant has been constructed in Garissa in Kenya, a city located at the equator where the sun is said to shine for about 3,144 hours each year on average, and it is expected to produce approximately 76,473 MWh/year. Ghana, which aims to produce 10% of its electricity from renewable sources by 2030, has commissioned several projects, including a floating solar power plant in the reservoir of the Bui Dam. There are also many small-scale modular solar power installations being implemented across the continent at the village and household levels. In 2015, Sub-Saharan Africa was the leading region for purchases of off-grid solar products.
