Why Nigeria's 1.7GW solar year is still waiting for a local panel maker

At 7am on Monday 19 October, Nigeria's grid was carrying 3,840 megawatts. By 1pm it was carrying 476.70MW, according to system operator data reported by TheCable, a fall of about 88% in 6 hours. Egbin, Jebba, Shiroro and Kainji were all producing nothing.

Days like that explain the other number. Ember, the energy think tank, expects Nigeria to install about 1.7 gigawatts of solar in 2026. Almost none of it is made here. That gap looks like an obvious business. The data say the opportunity is real, but it is probably not the one most people picture.

Market snapshot

• Segment: solar panels, batteries, inverters and installation for homes, shops, clinics and factories that cannot rely on the grid
• Type of market: distributed, mostly rooftop and off-grid, served by importers, distributors and installers
• Size: about 1.7GW of new solar in 2026 (Ember estimate); roughly 2.4GW of panels shipped from China in the 12 months to August 2026, worth about $269 million, according to China customs data cited by TheCable
• Main buyers: households in grid-weak areas, small businesses replacing petrol and diesel generators, commercial and industrial users
• Main spend lines: panels, lithium batteries, inverters, installation labour, maintenance and finance
• How good the data are: fair for imports, poor for installations and local output. Ember notes that no Nigerian manufacturer publishes its production figures.

What the numbers reveal

Start with how fast demand is growing. Nigeria imported 1,721MW of panels in the 12 months to June 2025, already Africa's second-largest importer after South Africa. The 2.4GW figure for the year to August 2026 is about 39% higher. The periods end 2 months apart, so treat that as an approximate growth rate, not an exact one.

Then the price. $269 million for 2.4GW works out at about $0.11 per watt for imported panels (my calculation). That is the price any Nigerian factory has to beat.

Now local supply. The Rural Electrification Agency puts national panel manufacturing capacity at 300MW, up from 120MW 2 years earlier, a 2.5x rise. On paper, that is about 18% local capacity against installs (300MW against 1.7GW). Capacity is not output, though. Deborah Fadeyi of Vectar Energy told TheCable that the only operational plant in Lagos produces under 20MW. If that is close to Nigeria's real output, local panels cover about 1% of the market.

The pipeline is big but stalled. Ember lists Tranos at 800MW (broken ground, no line commissioned), Solarge and InfraCorp at 1GW (no site) and Oando at 1.2GW (before an investment decision). That is about 3GW of announced capacity, about 1.8x this year's installations, and none of it is producing.

The services side is moving faster. Registered solar companies rose from 56 in 2019 to 370 in 2025, about 6.6x. And Ember says Nigeria is one of the markets where battery imports far exceed solar imports, as buyers use batteries to ride out outages instead of running diesel.

Why this market is untapped

The apparent gap is "Nigeria needs a panel factory." The demonstrated demand says something narrower.

Demand is proven, but not for local panels specifically. Buyers are paying for working power, not for where the panel was made. Ember's 2025 analysis found that diesel savings can repay a solar panel within about 6 months in Nigeria. TheCable's figures suggest generating the same power with diesel would cost about $980 million a year, roughly 3.6x the import bill for the panels.

Price is the barrier for local makers. At about $0.11 per watt, imported panels leave little room for a new factory that pays Nigerian power, financing and logistics costs. Africa as a whole made about 3.5GW of panels in 2026, roughly 20% of its installs, and China supplies 94% of panels installed on the continent.

Policy has wobbled. The plan announced in March 2025 to halt panel imports was walked back this month, when the minister of innovation, science and technology, Kingsley Udeh, said there would be no immediate ban and that all panels, imported or local, must meet quality standards. A protected market would have changed the maths. That protection is not coming soon.

The real gaps sit around the panel: batteries and inverters (the bigger import line), skilled installation, quality testing, after-sales service and finance for buyers who cannot pay upfront.

Who could serve it

Local SMEs and entrepreneurs: installation and maintenance is where the 6.6x rise in registered firms is happening. Barriers are low, but so is differentiation; certified installers with warranties and quality-tested kit are the ones likely to win repeat business.

Fintech and payments: pay-as-you-go and lease models for shops and households. The 6-month payback against diesel is the selling point, and the risk is collections when incomes are irregular.

Logistics and supply chain: battery and inverter distribution outside Lagos and Abuja, where the grid is weakest and demand for backup power is strongest.

Manufacturers: assembly of batteries and inverters, or panel lines tied to quality certification and government or commercial offtake, rather than competing head-on with imports on price.

A worked example, with assumptions labelled as mine. Suppose local makers won 20% of 2026's 1.7GW, or 340MW, at the import price of about $0.11 per watt. That is roughly $38 million of panel sales a year. A single 200MW line running flat out at that price would earn about $22 million a year in revenue, before costs, which is why panel-making only works with a cost edge or a guaranteed buyer. The battery and installation market around those same 1.7GW is likely to be larger, but there is no reliable public figure for it, and that data gap is itself part of the opportunity.

Risks and limits

• Naira risk: almost every component is imported, so prices move with the exchange rate.
• Quality and trust: cheap or fake panels damage the whole market, and new standards may raise costs before they raise trust.
• Policy reversal: a sudden import ban would raise prices for buyers before local supply exists.
• Data: installation and household spending figures are thin, so any market size beyond imports is an estimate.

What would change my mind

• A pipeline plant (Tranos, Solarge or Oando) commissioning a line and publishing output above 200MW a year. That would lift my odds on local panels reaching 10% of installs by 2028 from about 15% to about 35%.
• A firm, dated import ban with a phase-in schedule. That would raise the odds of a local panel industry and of higher prices at the same time.
• Ember's next count showing 2026 installs well below 1.5GW, which would suggest the boom is slowing and cut the case for every business in the chain.

Nigeria's solar boom is real and growing, but the money is more likely to be made around the panel than in making it. I'd put the odds that locally made panels supply less than 10% of Nigeria's installs in 2027 at about 85%, and the odds of a full import ban before the end of 2027 at about 15%.
