Solar Installation Cost Per kW in Nigeria, By Size
A fully installed commercial solar system in Nigeria costs ₦300,000–₦560,000 per kW, depending almost entirely on system size — the bigger the install, the lower your per-kW rate. This page shows exactly how that curve works, size by size.

Cost Per kW, Every System Size
Per-kW cost falls steadily as system size increases — from ₦560,000/kW at 5kW down to as low as ₦300,000/kW at 5MW.
| System size | Total price (approx.) | Cost per kW |
|---|---|---|
| 5kW | ₦2,800,000 | ₦560,000/kW |
| 10kW | ₦5,500,000 | ₦550,000/kW |
| 15kW | ₦8,300,000 | ₦553,000/kW |
| 30kW | ₦16,500,000 | ₦550,000/kW |
| 50kW | ₦27,500,000 | ₦550,000/kW |
| 100kW | ₦52,000,000 | ₦520,000/kW |
| 150kW | ₦76,500,000 | ₦510,000/kW |
| 200kW | ₦100,000,000 | ₦500,000/kW |
| 250kW | ₦125,000,000 | ₦500,000/kW |
| 300kW | ₦148,000,000 | ₦493,000/kW |
| 500kW | ₦240,000,000 | ₦480,000/kW |
| 1MW | ₦470,000,000 | ₦470,000/kW |
| 2MW | ₦680,000,000–₦820,000,000 | ₦340,000–₦410,000/kW |
| 5MW | ₦1,500,000,000–₦1,950,000,000 | ₦300,000–₦390,000/kW |
Figures are typical fully-installed prices divided by system size, based on Olasupo Energy installed-project data, 2026-08-08. Your exact per-kW cost still depends on battery capacity, site condition, and load profile — see below.
Why Bigger Systems Cost Less Per kW
The curve isn't arbitrary — four things drive the per-kW price down as scale goes up.
Bulk equipment ordering
Panels, inverters, and battery cells are ordered in far larger volumes at scale, lowering the per-unit landed cost.
Shared logistics costs
Shipping and clearing costs are spread across a much larger equipment volume rather than repeated per small order.
Fixed labor overhead
Site mobilization, project management, and design work cost roughly the same whether the system is 10kW or 5MW.
Simpler racking per kW
Larger ground-mount arrays use more standardized racking runs than the varied roof layouts smaller systems need.
What Moves Your Exact Per-kW Cost
The table above shows typical figures for a standard build. These four factors decide where you land within your size's range.
Battery capacity
The biggest single lever at any size — more backup hours means a bigger, more expensive battery bank.
Site condition
Roof condition or land grading, soil conditions, and access all shift mounting and civil works costs.
Cable run distance
Longer runs between panels, inverters, and the switchboard mean more cabling and higher labor hours.
Load profile
Continuous 24-hour loads need larger inverters and batteries than daytime-only operations, raising the total.
Estimating Your Own Cost Per kW
Find the row closest to your target size in the table above, then multiply its per-kW figure by your load. Example: a 150kW site at ₦510,000/kW works out to roughly ₦76,500,000 fully installed — matching the 150kW line above.

What Our Clients Say
"Seeing the per-kW number drop as size increased helped us justify going slightly bigger than our bare minimum load — the extra capacity cost less per kW than we expected."
Chidinma Okoro
Owner, Boutique Hotel, Lekki
"We used the per-kW table to sanity-check three vendor quotes before picking one. Olasupo's numbers were the most transparent about what moved us within the range."
Tunde Bakare
Facilities Manager, Manufacturing Plant, Ogun State
"Our site had a long cable run between the array and the switchroom, and the team was upfront that this would push our per-kW cost above the table figure before we signed anything."

Cost Per kW — Common Questions
What's a fair cost per kW for a commercial solar system in Nigeria?
It depends heavily on size. Small commercial systems (5–50kW) run ₦550,000–₦560,000/kW, mid-size systems (100–300kW) run ₦490,000–₦520,000/kW, and large systems (500kW+) run ₦300,000–₦480,000/kW.
Why is my quote higher per kW than the table shows?
The table reflects a standard build. Larger battery capacity, difficult site access, longer cable runs, or a continuous 24-hour load profile all push a specific quote above the typical figure for that size.
Does cost per kW include the battery, or just panels and inverter?
The figures here are for a complete hybrid system — panels, inverter, battery, racking, cabling, and installation — not panels or equipment alone. For panel-only pricing, see our commercial solar panel price page.
Is it worth going bigger than I need just to get a lower per-kW rate?
No — oversizing adds real cost even at a lower rate per kW. It's better to size against your actual load profile and let the per-kW table set expectations, not drive the decision.
How much would a 1MW system cost per kW?
Approximately ₦470,000/kW, or about ₦470,000,000 fully installed for a standard build — see the 1MW row in the table above.
