How Much Does Solar Cost in Nigeria? (2026 Guide)
The most common question we get on SolarBuilders.ng is: "How much will solar cost me?" The honest answer is: it depends. But this guide will give you real numbers, not vague estimates.
Quick Price Summary (2026)
| System Size | Best For | Price Range |
|---|---|---|
| 1–2 kVA | Lights, fans, phone charging | ₦150,000 – ₦350,000 |
| 3 kVA | Average home (no AC) | ₦380,000 – ₦600,000 |
| 5 kVA | Home with 1 AC unit | ₦650,000 – ₦950,000 |
| 7.5–10 kVA | Large home or small office | ₦900,000 – ₦1,500,000 |
| 15–20 kVA | Commercial / business | ₦1,800,000 – ₦3,500,000 |
What's Included in These Prices?
A complete solar installation in Nigeria typically includes four components: the inverter (the brain), solar panels (the energy source), batteries (the storage), and installation labour. When you see a quoted price from a verified installer on SolarBuilders.ng, it should include all four unless stated otherwise.
Be careful of quotes that seem too cheap — they often exclude batteries (the most expensive component) or use substandard brands. Always ask: "Does this price include everything, installed?"
What Drives the Price Up?
- •Battery type: Lead-acid batteries are cheaper but lithium batteries last 3× longer
- •Panel brand: Tier 1 panels (Longi, JA Solar) cost more but perform better
- •Location: Lagos and Abuja tend to have higher installation costs than other cities
- •System complexity: 3-phase systems and hybrid configurations cost more
- •Accessories: Monitoring apps, auto-transfer switches, cable management
What About ROI? When Does Solar Pay Back?
The average Lagos household running a generator spends ₦35,000–₦60,000 per month on fuel. A 3kVA solar system costs around ₦480,000 installed. At ₦40,000/month in generator savings, the system pays back in approximately 12 months. After that, the electricity is essentially free for the next 10–15 years.
Diesel prices have risen sharply since 2023. Every month you wait is another month of generator fuel costs that solar would have eliminated. The ROI on solar in Nigeria is genuinely excellent right now.
How to Get an Accurate Quote
The most reliable way to get an accurate quote is to first calculate your load — what appliances you actually run, for how many hours. This tells you (and any installer) exactly what size system you need. Without this, you risk buying a system that's too small (frustrating) or too large (wasted money).
Use our free solar calculator below to get your estimated system size first, then compare quotes from verified builders in your city.
Final Advice
Don't just go for the cheapest quote. Nigeria's solar market has plenty of cut-rate installers who use inferior components or skip critical steps like proper earthing and cable sizing. A slightly more expensive system from a verified, reputable installer will save you significantly in the long run.
