Business has never been as brisk for Nigerian solar panel retailer Samuel Okechukwu and his team of installation technicians, who are struggling to keep up with orders since the Iran war caused local fuel prices to double.
“There’s too much work, I’m even having to outsource some services to keep up with the work rate,” Okechukwu told Climate Home News, as he installed solar panels on the roof of an apartment building in the southern city of Port Harcourt.
Before the war, he had installations once or twice a week, but is now busy almost every day.
Okechukwu’s surge in orders in recent weeks suggests that more Nigerians are buying solar systems due to soaring fuel prices caused by the conflict in the Middle East, which has effectively blocked the Strait of Hormuz through which a fifth of the world’s oil and liquefied natural gas previously flowed.

Plagued by frequent failures on Nigeria’s national grid, many homes and businesses buy diesel and petrol to supply generators to keep the lights on and equipment operating.
Even before the latest fuel price shock, solar installations had been increasing in Nigeria in recent years as an alternative to generators among those able to afford the initial outlay.
It costs about 600,000 naira ($450) to buy just one inverter battery and two 300-watt solar panels to charge it – roughly 10 times the minimum monthly wage – and eyebrows were raised when the government announced last year that the presidential villa was being kitted out with a $6 million solar mini-grid.
Power plants hit by gas shortages
Nigeria’s erratic power supplies have become even more unreliable in recent weeks as gas shortages constrain already fragile power generation. Most of Nigeria’s electricity supply comes from gas-fired plants.
Last month, the Nigerian Independent System Operator said several of the oil- and gas-producing nation’s thermal power plants were being affected by “persistent gas supply constraints” that were causing a decline in electricity generation.
While Nigeria has abundant gas reserves, the shortages are largely driven by structural issues, including mounting government debts owed to gas suppliers and pipeline constraints. Power Minister Adebayo Adelabu said last week that gas suppliers are prioritising export markets which have become more attractive and offer better returns over domestic markets.
This week, the Nigerian government increased gas prices for power generation companies, a move likely to deepen cost pressures in the electricity sector already struggling with debt and supply shortages.
At the same time, Okechukwu said rising temperatures in recent years were also increasing demand for an affordable source of electricity to power air conditioners.
Global oil shock makes case for renewables
Installations of solar power in Africa jumped 54% in 2025, according to a report by the Global Solar Council (GSC), marking the fastest annual growth on record.
The continent’s solar power capacity still represents only about 1% of the world’s total, though industry experts say the continent may have significantly more than official data reflects, with many rooftop installations going uncounted.
Precarious power supplies are already a key driver of solar adoption in many African nations, propelling fast growth rates in countries including Nigeria, which was Africa’s second-largest solar installer last year, installing more than 800 MW of capacity, according to the GSC, a nonprofit trade body.
Surging energy costs due to the Iran war could give further momentum to growth, the GSC’s CEO Sonia Dunlop told Climate Home News.
“It’s clear the people of Nigeria saw the writing on the wall … and have gone all in on rooftop solar as a result,” Dunlop said.
The increase in energy prices since the conflict began have cost consumers and businesses around the world more than $100 billion, according to a March 2026 analysis by 350.org, a non-profit organisation.
It said that would be enough to build sufficient solar capacity to supply about 150 million people in lower-consumption countries, for example in Africa, adding that investing in renewables was the best way to stabilise prices and strengthen energy security.
Anne Jellema, 350.org’s CEO, urged governments meeting in Colombia next month to discuss the transition away from oil and gas to “seize this moment to adopt binding targets to phase out fossil fuels and ramp up investment in a clean, safe energy future”.

The global energy shock unleashed by the U.S.-Israeli war “definitely supports the case for longer-term mitigation, not being reliant on imported oil”, said Karl Boyce, CEO of ARC Power, a mini-grid developer operating in Africa, adding that securing sufficient investment would be crucial to realising Africa’s renewables potential.
“It’s so reliant on really heavy investment,” Boyce said. “So globally, there should be a focus on seeing how more investment can go into that sector just to give more stability in the longer term.”
“Forget about buying petrol”
In Port Harcourt, another solar trader, Sunday Onuchukwu, said his business has been “moving faster than before” as people get tired of power cuts and rising fuel costs that make investing in panels seem a better bet.
Located in a solar panels retail market, Onuchukwu’s shop was busy with customers, but the market itself was unusually quiet – without the usual whirr of generators thanks to the solar panels on the roof.
“Most of my customers complain that the fuel issue is one reason why they have decided to go solar. I have clients who transition both their offices and homes at the same time and move away from the bad power supply,” Onuchukwu told Climate Home News.
He said many businesses spend more than 20,000 naira ($15) per day on petrol to power generators.

“With that money, calculated over a one-year period, you can install solar and forget about ever buying petrol,” he said, adding that some lower-cost solar products were now becoming available such as a 50,000-naira ($36) kit that provides enough power to light a single bulb and charge a mobile phone.
Lifting two heavy panels onto his head in Onuchukwu’s shop, one customer said ensuring a steady supply of power – after months without mains supplies – was vital for his barber shop and would also help his wife’s small business.
“This is what I am using to run my business and ensure electricity,” the man said, giving his family name as Amadi.
“With these two panels, I can also power my wife’s inverter freezer for her to be selling frozen foods.”

Nigerians bet on solar as global oil shock hits wallets and power supplies
For the first time, new-energy vehicles (NEVs) made up 67% of new car sales in China in September, according to the latest data from the China Passenger Car Association (CPCA).
The figures show that NEVs, which include battery electric cars and plug-in hybrids, captured a record share of sales, even though fewer were sold than last year.
This is because sales of combustion-engine cars are falling steeply, a trend that the CPCA has attributed to rising petrol prices following the start of the Hormuz crisis.
Indeed, sales of fuel-only cars were down 31% year-on-year in the first nine months of 2026, with plug-in hybrid sales down 26% – whereas battery EV sales were only down 4%.
One analyst tells Carbon Brief that China’s rapidly growing EV fleet has offset demand for 143m barrels of oil since the start of the Hormuz crisis.
Another says that the crisis is “reinforcing China’s electrification of road transport”.
Meanwhile, amid slowing domestic sales, Chinese carmakers’ exports of NEVs more than doubled [in 2026 to date / in September] from a year earlier.
NEV record
A record two out of every three cars sold in September in China were NEVs, according to CPCA data, as shown in the figure below.
(NEVs predominantly include battery electric vehicles – BEVs – and plug-in hybrids – PHEVs. BEVs only run on electricity, whereas PHEVs also have a combustion engine.)
This marks a rapid rise for NEVs from just 6% of new car sales in 2020 up to 58% in 2026 to date – and a record 67% in the month of September.
This year, NEVs’ share of sales has also bounced back from a low of 39% in January, after the full purchase tax exemption that had been in place for more than a decade came to an end in December 2025.
The gain in NEV share in 2026 has come amid a slowdown across the wider domestic passenger-car market, which has hit sales of combustion-engine vehicles particularly hard.
This September, passenger-car retail sales across all categories declined, with overall sales volumes falling 28% year-on-year.
The contraction was led by combustion-engine vehicles, which saw sales fall 43% year-on-year in September and 31% in 2026 to date.
However, sales of PHEVs also fell by 36% year-on-year in September and by 26% in 2026 to date. By comparison, BEVs performed better, although sales still declined 8.5% from a year earlier in September and 4% in 2026 to date.
As a result, NEV sales overall fell by 17% in September and 13% in 2026 to date.
While the market changes in 2026 to date were particularly dramatic, they reflect a broad continuation of trends seen over the past decade.
Indeed, sales of combustion-engine cars in China peaked in 2017 and they have been declining ever since, shown in the figure below.
Impact of Hormuz
Part of the reason for the advance of NEVs in 2026, said Chinese technology news outlet OFweek, was petrol cars “giving up market share” as they were outperformed by electric alternatives.
Cui Dongshu, secretary-general of the CPCA, cited higher petrol prices as an explanation for September’s weak combustion-car sales, in comments to financial news outlet National Business Daily.
Imports of oil into China in January-September have fallen 15% compared to 2025, equivalent to 470m barrels, as ongoing conflict tightened supply and drove up prices.
China’s passenger-car NEV fleet has displaced 143m barrels of oil so far during the strait of Hormuz crisis, Euan Graham, senior energy analyst at thinktank Ember, tells Carbon Brief.
EVs “accounted for 12% of the decrease in China’s oil use post-Hormuz”, according to an estimate provided to thinktank the Brookings Institute by an unnamed analyst.
