Africa Solar Mini-Grids Market (2026-2036)

The growth of this market is mainly driven by the very large number of people in Africa without access to electricity, particularly in rural areas far from national grids, large electrification programs such as Mission 300, led by the World Bank Group and the African Development Bank, results-based financing and subsidy programs that support private mini-grid developers, the falling cost of solar panels and lithium-ion batteries, which makes solar mini-grids cheaper than diesel generation and grid extension in many areas, and growing demand for reliable power for businesses, farms, health centers, and schools. However, factors such as the high upfront cost of mini-grids and limited access to affordable finance, low electricity demand and ability to pay in many rural communities, regulatory and tariff uncertainty, currency risk, and the risk of the national grid arriving in mini-grid areas are expected to restrain the growth of this market to some extent.

A solar mini-grid is a small electricity generation and distribution system that uses solar photovoltaic panels, usually combined with batteries and sometimes a backup diesel generator, to supply electricity to a community, town, business cluster, or institution through a local distribution network. Mini-grids typically range from a few kilowatts to several hundred kilowatts or more and serve from a few dozen to several thousand customers. They can operate independently of the national grid, known as isolated mini-grids, or be connected to the grid, known as interconnected mini-grids, to improve reliability in areas where grid supply is weak.

This market covers the revenue generated from solar and solar-hybrid mini-grid systems and services in Africa, measured in value. It includes battery energy storage systems, solar PV modules, distribution networks and smart meters, inverters and controllers, balance of system components, installation and engineering, procurement, and construction services, and operation and maintenance services, for isolated and grid-interconnected mini-grids of all capacities serving residential, commercial, productive use, public institution, telecom, and other customers. It is segmented by component, grid connection, configuration, capacity, end user, and country. Revenue from electricity sales by mini-grid operators, solar home systems, standalone solar products, and utility-scale solar plants is not included.

Africa has the largest electricity access gap in the world, with most of the people without electricity living in sub-Saharan Africa, many in rural areas far from the national grid where grid extension is very expensive. Solar mini-grids have become one of the main solutions for these areas, because they can provide reliable electricity for households, businesses, and public services at a lower cost than extending the grid or using diesel generators, and they can be built quickly. The World Bank and other development partners estimate that a large share of new electricity connections in Africa by 2030 will come from off-grid solutions, including mini-grids.

Most mini-grids in Africa are built and operated by private developers, which finance the systems with a combination of equity, debt, and grants or subsidies, and recover their costs by selling electricity to customers, usually through prepaid smart meters and mobile money payments. Because rural customers often have low incomes and consume little electricity, tariffs that fully recover costs can be high, and many projects depend on subsidies, such as results-based grants per connection, to be viable. Governments, development finance institutions, and donors provide much of this support through programs such as Mission 300, Nigeria's Distributed Access through Renewable Energy Scale-up project, and other national electrification programs.

The cost of solar mini-grids has fallen significantly over the past decade, mainly because of lower prices for solar panels and lithium-ion batteries, improvements in system design, standardized and modular designs, and remote monitoring. Lithium iron phosphate batteries have largely replaced lead-acid batteries in new mini-grids, offering longer life and better performance. Smart meters and digital platforms allow operators to manage customers, collect payments, and monitor systems remotely, which reduces operating costs.

Mini-grids are increasingly designed to support productive uses of electricity, such as grain milling, agro-processing, cold storage, welding, water pumping, and small manufacturing, which increase electricity demand, improve the economics of mini-grids, and create local economic development. Developers also serve anchor customers, such as telecom towers, health centers, schools, and businesses, which provide stable demand.

Mini-grids also offer advantages over solar home systems, which provide small amounts of power to individual households. Mini-grids can supply larger loads, such as motors, refrigeration, and machinery, which are needed for businesses and public services, and they can provide a service similar to grid electricity. As a result, solar home systems and mini-grids are increasingly seen as complementary, with solar home systems serving very dispersed households and mini-grids serving villages, towns, and business clusters.

Over the forecast period, the Africa solar mini-grids market is expected to grow rapidly, supported by Mission 300 and national electrification programs, falling costs, improved financing, and growing demand for productive use and interconnected mini-grids. Growth will depend on the availability of affordable finance, regulatory frameworks that protect mini-grid investments, and the ability of developers to scale their operations profitably.
