How Much Does Solar Cost in Nigeria? (2026 Price Guide)

According to market data, a home solar system in Nigeria typically costs between ₦2.5M and ₦8M, while larger homes and small businesses can run from ₦10M upwards. That range is only a starting point, because the right price depends on how much power you use, whether you want battery backup, and which payment option you choose.

The good news is that you don't have to pay it all at once. As well as buying a system outright with a Cash Purchase, you can spread the cost with a Financed Purchase (a loan you repay in monthly instalments) or Energy as a Service (a fixed monthly subscription).

This guide breaks down what you can expect to pay in 2026, what actually drives the cost, and how to get a fixed price for your own home or business.

The single biggest driver of your price is the size of system you need, which comes down to how much power you use. As a rough guide, here is what different system sizes cost and power in Nigeria:

• A basic home system (1–2kVA) costs around ₦2.5M–₦3.5M and powers lights, fans, a TV, phone charging and a fridge. It suits a small flat or a straight generator replacement for the essentials.
• A standard home system (3–5kVA) costs around ₦3.5M–₦6M and adds a freezer plus one air conditioner for part of the day.
• A large home system (5–10kVA) costs around ₦6M–₦12M and runs multiple ACs, a bigger fridge or freezer and heavier appliances for longer.
• A business or commercial system (10kVA+) starts from ₦12M and is sized to your specific offices, shops or light industrial loads.

These ranges include panels, inverter, batteries and installation. Your final price moves up or down depending on how many hours of backup you need and the quality of components you choose.

You do not need to be an engineer to get a rough figure. There are two simple ways to estimate what you need:

• Your electricity bill is the quickest guide, since the monthly kWh figure shows roughly how much power a system needs to cover.
• The power ratings of your appliances give a more tailored figure, based on what you most want to run and how many hours a day each is used.

You can use our appliance survey to calculate your daily, monthly and yearly energy usage for you, based on your appliances and how you use them.

A solar system is four parts working together. Here is roughly how the cost splits across them:

Component	What it does	Typical share of cost
Battery storage	Keeps your power on after sunset and during outages. Lithium lasts far longer than tubular or lead-acid.	~40%
Solar panels	Turn sunlight into electricity. Long-lasting (25–30 years) and rarely the most expensive part.	~25%
Inverter	Converts power to usable AC and manages solar, battery and grid. A hybrid inverter lasts 5–10 years.	~20%
Installation and components	Cabling, mounting, safety gear and the installer's workmanship.	~15%

Because the battery is the single biggest line, the number of backup hours you ask for moves your price more than almost anything else. It is also the component that varies most between quotes, so it is worth comparing battery type and usable capacity closely.

A typical 3-bedroom Lagos home uses around 15 kWh a day and spends roughly ₦170,000 a month running a petrol generator. That usage comes from a familiar mix of everyday appliances:

Appliance	Typical daily use
LED lighting	~1 kWh
Ceiling and standing fans	~2 kWh
Fridge and freezer	~3 kWh
TV and decoder	~1 kWh
Two air conditioners (evenings)	~6 kWh
Water pump	~1 kWh
Phone and laptop charging	~1 kWh
Total	~15 kWh/day

Now compare the running costs on the generator against a solar system sized for the same home:

Per month	Generator today	Solar with Senergy
Fuel	₦150,000	₦0
Servicing & parts	₦20,000	~₦2,000
Total running cost	₦170,000	near ₦0 after payback
Cost per unit (kWh)	~₦550	~₦110

At those rates, running a generator costs roughly five times more per unit of energy than solar. That adds up to about ₦2M a year on fuel and servicing, a recurring cost that never stops and never builds into an asset you own.

Swapping to solar removes almost all of that running cost. How soon the saving shows up depends on which payment option the home chooses:

Payment option	Upfront	Monthly cost	Savings
Cash Purchase	~₦5M	~₦0, just upkeep	Breaks even in about 2.5 years, then around ₦2M saved every year
Financed Purchase	A percentage of the price upfront	Instalments for 6–12 months, then ~₦0	Same long-run saving once repaid, and you own the system
Energy as a Service	₦0	Below the old ₦170,000 fuel bill	Saves from the first month, with the installer owning and maintaining the system

Whichever option they choose, the sticker price of solar is not the number to watch. The cost per unit of energy over the system's life is what leaves this home better off.

Figures are illustrative and depend on your usage, location and the quotes you receive.

You don't need the full amount upfront. If you would rather not buy the system outright with a Cash Purchase, there are two ways to spread the cost:

• Financed Purchase lets you put down a deposit and repay the balance over 6–12 monthly instalments, and you own the system from day one.
• Energy as a Service is a fixed monthly subscription with no large upfront cost, where the installer handles installation and maintenance for you.

For many households the monthly repayment is close to, or less than, what they were already spending on fuel. See our solar financing options to compare how each plan works.

Every home is different, so the only way to know your real number is to get quotes based on your actual energy use. With Senergy you can compare fixed-price quotes from vetted Nigerian installers side by side, for free, with no home visit required.
