Chinese solar panel exports into Africa cost $2.4 billion in the twelve months to June 2026, according to new analysis from Ember and the African Tech Futures Lab. Generating that same amount of electricity from diesel would cost roughly that much again — every three months.
The imported panels effectively pay for themselves in diesel savings within a single quarter, then keep saving for the 30 years or more they typically last.
That economic gap, plus rising diesel prices following the US-Iran conflict and subsidy removals in countries including Nigeria and Egypt, is why solar’s growth increasingly reflects a fuel-substitution trend.
Record solar capacity of 17GW will be installed in Africa in 2026, up 45% year-on-year.
Batteries are growing faster than the panels
The most obvious sign of that shift, says Dave Jones, chief analyst at Ember, is what’s happening to battery imports. “Africa for two years now has been importing more dollars of batteries from China than it has of solar panels, which is an incredible stat,” he said during an online briefing for the report.
“The value of solar panels has doubled in the last two years of imports, but quadrupled for batteries.”
On its own, solar only covers daylight hours, meaning gensets still operate in communities after dark. To displace a diesel generator that runs into the evening, businesses and homes need storage alongside it.
“Diesel’s just got so expensive now… you have solar to obviously reduce the amount of diesel you need, but actually to continue that into the evening, you need a bit of battery to go with that as well,” Jones said. “Solar and battery together are really now turning out to be the new diesel generator.”
Nigeria and the DRC lead the battery import surge, for different reasons.
In Nigeria, Jones explained, households and businesses are buying batteries to bridge loadshedding hours rather than running generators.
In the DRC, the motivator is industrial. A copper mine near the Zambian border was previously supplied by a diesel generator, with fuel trucked from Kinshasa roughly 1,000 kilometres away.
According to Jones, the mine has procured around-the-clock power through solar plus storage. CrossBoundary Energy commissioned the project, the first of three companies now installing similar systems at the site.
A growth, not replacement trend
Jones is careful to frame the shift as additive rather than substitutive. “This for me is more of a growth story,” he opined.
“It’s not a replacement story. It’s about people using electricity that they didn’t have access to before, to do things with that they weren’t able to afford to do before.”
He points to Pakistan as a preview of where Africa’s distributed solar-and-battery boom could lead. Electricity demand there rose 22% in two years, entirely met by newly installed distributed solar.
“A lot of that has not been from just meeting excess demand — it’s actually driving that demand in the first place,” Jones says. “People are using solar because they want air conditioning. They’re not going to be able to afford air conditioning using grid electricity in the first place.”
With battery costs falling alongside panel prices, Jones sees a further leap ahead.
“There’s a real possibility of leapfrogging more directly to the electricity-based energy system, predominantly driven by solar and battery”, and bypassing the baseload grid many other regions built their power systems around.
