Why the Demand Is Real, and Where the Money Actually Is
Nigeria has the largest off-grid population in the world, with upwards of 80 million people lacking a reliable grid connection, and the households and businesses that are connected are still buying fuel for generators. Removing a ₦60,000-a-month diesel bill is a proposition that sells itself. This is not a market you have to create.
What is harder is making money in it, because the barrier to entry is low and the market is crowded with people who bought a few panels and a van. The installers who build real businesses do one of three things:
Specialise
Pick a segment and own it. Medical facilities needing uninterrupted cold-chain power. Telecom sites. Schools. Filling stations. Boreholes and irrigation. Specialists quote faster, buy better and command higher prices than generalists.
Sell on credit
Almost nobody can pay ₦900,000 up front. The installer who offers a deposit plus twelve monthly payments sells to a market ten times larger than the cash-only one. This turns you into a lender as much as an installer, which is a real decision.
Build a service book
Annual maintenance contracts, battery replacement cycles, monitoring and fault response. Recurring revenue that smooths the lumpy installation calendar, and it is where the reliable profit sits once you have a few hundred systems in the field.
Skills and Certification
There is no single mandatory national licence to install a domestic solar system in Nigeria, which is exactly why the market has a quality problem and why demonstrable competence is a commercial advantage rather than a formality.
Get properly trained
Solar photovoltaic design and installation training covering load assessment, array sizing, battery banks and depth of discharge, charge controllers, inverter selection, wiring and protection, earthing and lightning protection. A decent programme runs a few weeks. If you cannot calculate a load profile and size a battery bank correctly, you will undersize systems, blow batteries early and spend your margin on warranty callbacks.
Electrical competence and safety
You are working with mains AC and substantial DC currents. Either hold the relevant electrical qualification yourself or employ someone who does. Poor earthing and undersized DC cabling cause fires, and a single serious incident ends the business.
Industry affiliation and standards
Association membership, such as the Renewable Energy Association of Nigeria, and familiarity with SON standards for the equipment you install. For larger commercial and grid-interactive work, understand where NEMSA inspection and NERC's framework apply. Internationally recognised certification carries real weight when quoting institutional and donor-funded work.
Register the business
CAC registration, TIN and a corporate account. Institutional buyers, NGOs and corporates will not contract with an individual, and those are the clients worth having.
Startup Cost
| Item | Typical cost | Notes |
|---|---|---|
| Training | ₦150,000 – ₦600,000 | Per person. The cheapest insurance you will ever buy against callbacks. |
| Tools | ₦400,000 – ₦1,200,000 | Drills, crimpers, cable tools, multimeter, clamp meter, insulation tester, ladders, safety harness, PPE. Buy a proper clamp meter and insulation tester — diagnosing faults by guesswork costs more than the instruments. |
| Transport | ₦3,000,000 – ₦12,000,000 | A used van or pickup. You can start by hiring per job, and many do. |
| Demonstration system | ₦500,000 – ₦1,500,000 | Install one at your own premises. Being able to show a working system closes more sales than any brochure. |
| Working capital | ₦1,500,000+ | The real constraint. Clients pay a deposit; you buy the equipment; you get the balance on completion. You are financing the gap on every single job. |
| CAC, insurance, marketing | ₦300,000 – ₦800,000 | Public liability cover matters once you are working in other people's buildings. |
A realistic install-only start is ₦2,000,000 to ₦4,000,000, hiring transport and buying equipment per job. Holding stock and running your own vehicle takes it past ₦10,000,000. Start without stock: order against a confirmed deposit until your volume justifies inventory.
Quoting and Margin: Where Installers Lose Money
Nigerian solar quoting fails in predictable ways, and each one comes straight out of your margin.
- Sizing from the client's wishlist instead of a load audit. Walk the building, list every appliance, get real running and surge wattages, and establish how many hours of autonomy they actually need. A client who says "just the fridge, TV and lights" has forgotten the pressing iron and the water pump, and it is your battery bank that will pay for it.
- Quoting in naira against dollar-priced equipment. Panels, inverters and lithium batteries are priced against the dollar. A quote that stands for thirty days while the rate moves is you absorbing the currency risk. Put a validity period on every quote — seven to fourteen days — and honour it, no longer.
- Forgetting the invisible costs. Mounting structure and roof work, cable runs that turn out to be forty metres not fifteen, changeover switches, a distribution board upgrade, lightning protection, scaffolding, transport, and the second visit. Itemise them or absorb them.
- Quoting a price instead of a saving. "₦1.8 million" invites haggling. "₦1.8 million, replacing ₦55,000 a month in diesel and generator servicing, so it pays back in about thirty-three months and then runs for years" is a different conversation entirely. Put the payback arithmetic on every quote.
- Not writing down what is excluded. The scope document should state plainly what the system will and will not run, expected autonomy, what voids the warranty, and what is not included. Most disputes are scope disputes.
Gross margins of 15% to 30% on equipment plus labour are typical for a competent installer. Below that you are buying badly or quoting fearfully; well above it and you are either specialised or about to lose the job.
Warranty: The Risk That Quietly Kills Solar Businesses
You will be blamed for every fault, whoever caused it. When a battery dies in month fourteen, the client does not ring the manufacturer. They ring you, and they expect it replaced free. Installers who have not managed this exposure deliberately find that year two consumes the profit they made in year one.
How to manage it:
- Buy from suppliers who honour warranties and keep the paperwork. Cheap batteries from a supplier who vanishes are the most expensive components you can fit.
- Record serial numbers against every installation. When a claim comes, you need to prove which unit went where and when, or the manufacturer will not entertain it.
- Separate your workmanship warranty from the equipment warranty, in writing, and explain the difference to the client at handover rather than during the argument.
- State what voids cover. Clients connecting an air conditioner to a system sized for lights and a television is the single most common cause of failure, and it is not your fault unless your paperwork says nothing about it.
- Price maintenance in. An annual service contract funds the callbacks, catches problems early, and turns a cost centre into recurring revenue.
- Track fault rates by product and supplier. The moment you can see that one supplier's batteries fail at eighteen months, you stop buying them — and without records you will not see it for years.
Selling on Instalments, and the Software Behind It
The moment you offer a deposit plus monthly payments, your addressable market expands enormously and your business changes character. You are now carrying a receivables book, and the operational problem is no longer installation, it is collection.
This is the model Lumos proved in Nigeria: a modest amount down, a fixed monthly payment, and the system remotely disabled if payment stops. PAYG-capable hardware generates a token the customer keys in after paying, or is enabled and disabled remotely over GSM. Without that control, instalment selling in this market is a donation programme.
What stops working once you pass roughly two hundred customers is the spreadsheet. You cannot tell who is in arrears, how much is outstanding across the book, or which agent's customers default most. What you need is:
- Every customer's schedule, balance, days in arrears and next due date as a live number.
- Token generation tied to payment, idempotent so a customer who retries after a network drop is never charged twice.
- USSD payment so a customer with a feature phone pays and receives the unlock code in the same session.
- Automated reminders before due date and escalating follow-up after it.
- An offline agent app for registration, stock, installation sign-off and cash collection in places with no network.
- Portfolio-at-risk reporting, which is what any financier funding your book will ask for first.
We build exactly this. An installer operations system covering quoting, jobs, inventory by serial number and after-sales runs ₦6,000,000 to ₦10,000,000; a full PAYG platform with the lending engine, remote lock and collections runs ₦12,000,000 to ₦22,000,000. Detail on our solar PAYG and installer software page. Start with the loan book and collections module alone — eight to ten weeks, and collection rates usually move on automated reminders inside two months.
