What a Nigerian Solar System Actually Costs — Every Component, Every Price

A 5kVA · 10kWh lithium system — a family home with one AC — is ₦3,200,000–₦4,800,000 installed, at prices last checked September 2026. Below is every component that makes up that number, per kVA, per kWh and per watt, so you can check any quote you have been given against it.

Installed price, by system size

Everything included: inverter, lithium battery, Tier-1 panels, mounting and protection, and installation labour. Import duty and VAT on panels, inverters and batteries are 0%.

A real build, itemised

Ranges are useful for budgeting and useless for checking a quote. So here is one actual system, priced line by line — our how many solar panels do i need for a 3 bedroom flat in nigeria? load at the Standard build: 4.3kW if everything runs at once, 15.8kWh a day.

Range ₦5.67M – ₦9.66M. Quote SB-6K-MTQ55T. Full working on the sizing page for this load.

1. Inverters — ₦ per kVA

The inverter is the brain, and its size is set by the largest set of loads you might run simultaneously — not by your roof and not by your budget. Price it per kVA, because that is the only way to compare a 3.5kVA unit against a 10kVA one.

To use it: multiply by the kVA you need. A 5kVA budget-class inverter should land around ₦550,000; the same size in premium class around ₦1,500,000. If your quote is far outside that, the question is which class you are actually being sold. We rank every brand we track on measured ₦/kVA in the best solar inverter in Nigeria.

2. Lithium batteries — ₦ per kWh

The battery is the biggest line on almost every Nigerian quote, and the one where the difference between a good and a bad purchase compounds for a decade. The market standard is a 5.12kWh 48V LiFePO4 module — about ₦1,049,600 in mid class.

Tubular lead-acid is still sold widely: a 200Ah 12V unit is ₦160,000–₦300,000. It looks much cheaper and is not, once you account for the half of it you are not allowed to use and the number of times you buy it again. We work that out in full in lithium vs tubular batteries.

3. Panels — ₦ per watt

Panels are the commodity part of the system and the easiest line to check, because everything is priced per watt. Tier-1 mono and bifacial modules run ₦185–₦300 per Wp, which puts a 550W panel at ₦101,750–₦165,000, typically around ₦126,500. Brands we track: Jinko, JA Solar, Longi, Trina, Canadian Solar.

At the naira rate we priced against, the low end is roughly $73 a module landed. That is a genuinely thin number, which is why a panel quoted well below it is the single most reliable warning sign in the market — the full set of checks is in how to tell a real solar panel from a fake one.

4. The costs quotes hide

Two lines are missing from most Nigerian quotes, and they are the two that decide whether your system is still working in year five.

• •Mounting, cables and protection — rails, DC and AC cable, breakers, surge protection, combiner box, earthing, changeover. We price this at 8–18% of equipment cost, which on the build above is ₦700,068. It is where corners get cut, because nobody photographs a surge arrester for Instagram.
• •Installation and commissioning — ₦20,000–₦60,000 per kVA for a Lagos, Abuja or Port Harcourt roof mount, with a floor of about ₦100,000 because a small job still takes a crew a day. On the build above, ₦180,000. Transport outside the city is extra and should be agreed before work starts, not discovered on the invoice.

Optional but frequently needed, and frequently left out of the comparison: avr / stabiliser (5kva) at ₦100,000–₦300,000, automatic changeover (63a) at ₦15,000–₦160,000, and a wifi monitoring dongle at ₦30,000–₦50,000. The dongle is the one people skip and later wish they had not — without production data you cannot tell dust from a fault.

5. Why the same item varies so much between sellers

Look at the spread in any row above — on panels alone it is about 62% from the bottom of the range to the top, for the same class of product. That is not noise. It reflects four real things:

• •Where in the chain you are buying. The low column is the bulk-wholesale floor — container quantities at Alaba. The high column is a single unit from a showroom or a marketplace listing, with someone’s warehousing, financing and returns risk priced in. Both are real prices for the same object.
• •Model generation. Manufacturers run several lines under one brand name. A cheaper off-grid line and a flagship hybrid can sit ten centimetres apart in the same shop with the same badge on them, and only the model number tells you which is which.
• •The naira. All of this is dollar-priced upstream. When the rate moves, every number on this page moves with it, which is exactly why the date at the top matters more than the figures do.
• •What the buyer appears to know. Uncomfortable, but true: the price a Nigerian buyer is quoted varies with how much they seem to understand. A published price list is the cheapest defence available against that.

6. Our method, and what “priced” means here

Every figure on this page comes from a price research exercise over live Nigerian vendor listings — around 130 priced data points across 38 sellers, each recorded with the vendor, the source page and the date it was seen. Those individual listings, with their sources, sit on the brand pages and in the shop. This page is the per-unit summary of them.

What that means in practice: “low” is the bulk-wholesale floor, “typical” is what a buyer in Lagos or Abuja can realistically get, and “high” is showroom or single-unit marketplace pricing. The snapshot date is September 2026. It is a snapshot and we say so — a price guide without a date is not a price guide, and several of the pages that rank for this question in Nigeria carry prices that are years old with nothing on the page to tell you.

And the disclosure that belongs in any article about prices: we make our money on procurement margin when we buy on a customer’s behalf. Publishing the floors is not charity — it is the reason to trust the rest.

7. How to use this to check a quote

1. Get it itemised. If your quote is one number, ask for the component list with model numbers. That request alone tells you a great deal about who you are dealing with.
2. Divide each line by its unit. Inverter price ÷ kVA. Battery price ÷ kWh. Panel price ÷ watts. Now compare with the tables above.
3. Check the class matches the price. A premium-class price for a budget-class inverter is the most common overcharge in this market, and it is invisible until you divide.
4. Check what is missing. Mounting, protection, earthing, changeover, commissioning. A quote that omits them is not cheaper, it is incomplete.
5. Check the sizing before the price. The cheapest quote for the wrong system is the most expensive thing on this page.

Then run the same load through our calculator and put the two itemised lists side by side. Where they differ, you have a specific question to ask rather than a general unease. If you want the payback arithmetic on top of the price, it is in is solar worth it in Nigeria; if the person quoting you is the thing you are unsure about, start with how to check your installer is qualified.
