Every morning for eleven years, Chukwuemeka Duru started his day the same way by yanking a pull cord on a 45-kilowatt diesel generator behind his Mobil filling station on Lagos-Ibadan Expressway, bracing himself for the roar and the fumes.
Last October, he yanked it for the last time. A 72-panel solar array now sits on a steel frame above his forecourt canopy, feeding a battery bank that powers his pumps, his point-of-sale terminals and the fluorescent tubes that stay on all night.
“The generator was eating N180,000 in diesel every week,” Duru said, standing beneath the panels as a tanker pulled in. “Now my electricity cost is almost zero. I recovered the installation cost in eight months.”
Duru is not alone. Across Nigeria’s roughly 14,000 licensed filling stations, a quiet but accelerating transition is underway.
Operators who spent decades treating diesel generators as an unavoidable cost of doing business in a country where grid power is both scarce and unreliable are now choosing solar and battery storage instead.
The shift, driven by a combination of economics, technology costs, and a government policy shock two years in the making, is reshaping one of the most visible industries in Nigerian commercial life.
The trigger was the fuel subsidy removal of May 2023. When President Bola Tinubu scrapped a decades-old petrol subsidy in his inauguration speech, the price of diesel, which had never been subsidised, barely moved.
But the broader economic convulsion that followed, a collapse in the naira and a cascade of input-cost inflation, pushed the price of running a generator-dependent business to a level that squeezed margins to the breaking point.

A litre of diesel that cost N750 in early 2023 was trading above N1,600 by the middle of 2024. For a large station running two generators around the clock, the monthly fuel bill could easily exceed N3 million.
At the same time, the landed cost of solar panels in Nigeria has fallen sharply. Chinese manufacturers, facing overcapacity at home and tariff pressure in Western markets, have redirected exports to Africa. Industry figures from the Nigeria Renewable Energy Association suggest the cost of a commercial rooftop solar installation fell by roughly 35 percent in naira terms between 2022 and 2025, even accounting for currency depreciation.
Lithium-iron-phosphate battery packs, less volatile than earlier chemistries and better suited to tropical heat, have become more available through distributors in Lagos, Kano and Port Harcourt.
“You now have a perfect storm of conditions,” said Adaeze Ike, head of commercial energy at Abuja-based consultancy Voltara Energy Partners, which has designed solar systems for more than 80 filling stations over the past two years. “High diesel prices, cheaper solar hardware, improving battery technology, and station owners who are finally doing the maths properly. The numbers work. They didn’t five years ago.”
The economics vary by location and load profile, but the broad picture is consistent. A mid-sized station consuming roughly 200 kilowatt-hours per day, enough to run six dispensing pumps, lighting, air-conditioning and a car wash. might spend between N35 million and N55 million on a solar-plus-storage system.
At current diesel prices, the same station was spending N80 million or more per year on generator fuel. Payback periods of 18 to 30 months are now routinely cited by installers, compared with five years or more just three years ago.
Not everyone has made the leap. In cities like Maiduguri and Jalingo, where access to capital is more constrained and local solar supply chains are thinner, diesel generators remain the default. Smaller stations in rural areas often lack the roof space or structural capacity for the arrays that larger forecourt canopies can accommodate.
The Petroleum Products Retail Outlets Owners Association of Nigeria estimates that fewer than 12% of the country’s stations have so far made a full or partial switch to solar — but that share has nearly tripled since 2023, and association officials expect it to double again within two years.
