What a complete solar system costs in Nigeria
A complete solar system in Nigeria typically costs between ₦1.5 million and ₦15 million, depending on the size of your home and how much of your power consumption you want to replace. The range is wide because there's a huge difference between a basic 2 kVA system that covers lights and fans, and a full 10 kVA hybrid system that runs air conditioning and heavy appliances.
This page breaks down every component cost, shows you real price ranges for common home sizes, and explains what you're actually paying for when you commission a solar installation in Nigeria.
Complete system costs by home size
These are fully installed prices — panels, inverter, batteries, mounting, cabling, and labour. Based on quotes collected from verified Nigerian installers, Q3 2025.
Suitable for a 1–2 bedroom flat with moderate usage. Will power LED lights, ceiling fans, phone charging, small TV, and a mini fridge. Won't run air conditioning or electric iron.
The most common system size for Nigerian homes. Powers a full 3-bedroom house — lights, fans, fridge, TV, washing machine, and small pumps. Not designed for regular AC use.
For homes that want to run 1–2 air conditioners. A 5 kVA system can handle a 1.5HP inverter AC during daylight hours alongside all other household loads.
For large homes or small offices that need full power independence. Runs multiple ACs, a borehole pump, and all appliances continuously through solar and stored battery power.
Component-by-component cost breakdown
A complete solar installation has five major cost components. Here's what each typically costs in Nigeria in 2025 and what it does:
Solar panels
The panels capture sunlight and convert it to DC electricity. Price depends on wattage and brand. Most homes use 6–16 panels of 400–450W each.
Solar inverter
Converts DC power from panels into usable AC electricity. A hybrid inverter also manages battery charging from both solar and grid/generator. Growatt and Felicity are most common in Nigeria.
Battery storage
Stores excess solar energy for use at night or on cloudy days. Lithium iron phosphate (LiFePO4) batteries are now standard — they last 10+ years and don't require maintenance like older lead-acid types.
Mounting hardware & cabling
Includes roof mounting frames, DC and AC cabling, combiner boxes, circuit breakers, and earthing. Often underestimated in budget planning.
Installation labour
Covers site assessment, panel mounting, inverter setup, wiring, system commissioning, and a post-installation walkthrough. Labour costs vary by company and region.
Itemised cost for a typical 3-bed home (3 kVA system)
Here's what a standard 3 kVA hybrid system — the most common size for Nigerian homes — typically costs when broken down by component:
| Component | Specification | Low estimate | High estimate |
|---|---|---|---|
| Solar panels | 6 × 400W Tier-1 mono | ₦780,000 | ₦1,140,000 |
| Hybrid inverter | 3 kVA Growatt / Felicity | ₦270,000 | ₦450,000 |
| Lithium battery | 10 kWh LiFePO4 | ₦450,000 | ₦750,000 |
| Mounting & racking | Aluminium roof frame | ₦60,000 | ₦120,000 |
| Cabling & components | DC/AC cables, breakers, earthing | ₦50,000 | ₦120,000 |
| Installation labour | 2–3 day installation team | ₦80,000 | ₦200,000 |
| Total (installed) | Full working system | ₦1,690,000 | ₦2,780,000 |
Why installer quotes are often higher than this
Reputable installers include margins for warranty support, after-sales visits, and project management. A quote of ₦2.5–3.5M for this system from a professional company is reasonable and accounts for the value of a managed installation with post-commissioning support.
Questions about solar system costs in Nigeria
₦2 million can buy a complete working solar system for a modest 2–3 bedroom home — but you'll be at the budget end of the market. Expect a 2–3 kVA hybrid inverter, 4–6 panels of 400W, and 5–10 kWh of lithium battery. It will cover lights, fans, TV, fridge, and phone charging. It won't comfortably run air conditioning. Spending ₦2.5–3.5M gives you meaningfully better components and a more reliable system.
In most Nigerian residential installations, the battery storage is either the most expensive single component or very close to it. A quality 10 kWh lithium battery can cost ₦450,000–₦750,000 on its own. If you want more storage (say 20 kWh for heavy usage), batteries can account for 40–50% of the entire system cost. Panels and inverter together are usually cheaper than the battery for equivalent-sized systems.
Yes, and many Nigerian homeowners do this. A common approach is to start with a smaller inverter and battery that can be expanded later, then add panels and additional battery capacity over time. However, staged installation has hidden costs — additional labour, potential rewiring, and not all inverters support battery expansion easily. Discuss expansion plans upfront with your installer so the system is sized and spec'd to grow with you.
Most installer quotes for residential solar systems do not explicitly include VAT. For commercial installations, your installer should invoice with VAT at 7.5%. Always clarify whether a quote is VAT-inclusive or exclusive, especially for business installations where input VAT credit may be reclaimed.
