Lagos has the most competitive solar market in Nigeria. Proximity to Apapa port and Alaba International Market means component prices are lower here than almost anywhere else in the country. But "lower" is relative — a complete, properly installed solar system is still a significant investment. Here are real installed prices for 2025.
Installed Solar System Prices in Lagos 2025
The prices below are for fully installed systems including panels, batteries, inverter, mounting frames, DC/AC cables, circuit breakers, and labour. They represent mid-range component brands (Growatt or Deye inverter, Jinko or JA Solar panels, Luminous or Amaron tubular batteries). Lithium battery options add 30–60% to the battery portion.
| System Size | Best For | Typical Spec | Tubular Cost | Lithium Cost |
|---|---|---|---|---|
| 1.5kVA | 1–2 bed flat, no fridge | 2 panels · 2 batteries | ₦485k – ₦900k | ₦750k – ₦1.3M |
| 2kVA | Small flat, small fridge | 3 panels · 2 batteries | ₦700k – ₦1.2M | ₦1M – ₦1.8M |
| 3kVA | 2–3 bed home, fridge + fans | 6 panels · 4–6 batteries | ₦1.8M – ₦3M | ₦2.5M – ₦4M |
| 5kVA | Full home + 1 AC | 8 panels · 8 batteries | ₦2.8M – ₦4.5M | ₦4M – ₦6M |
| 7.5kVA | Large home, multiple ACs | 12 panels · 10 batteries | ₦4.5M – ₦7M | ₦6.5M – ₦9.5M |
| 10kVA | Large home / small office | 16 panels · 12 batteries | ₦6M – ₦9M | ₦8.5M – ₦13M |
What Makes Up the Cost: Itemised Breakdown
For a reference 3kVA system (Growatt hybrid inverter, 6 × 400W Jinko panels, 6 × 200Ah Luminous tubular batteries), the cost breakdown in Lagos mid-2025:
| Component | Spec | Low | High |
|---|---|---|---|
| Solar panels | 6 × 400W Jinko/JA Solar | ₦420,000 | ₦600,000 |
| Batteries | 6 × 200Ah tubular | ₦360,000 | ₦540,000 |
| Inverter | Growatt 3kVA hybrid | ₦280,000 | ₦380,000 |
| Mounting frames | Roof/ground mount set | ₦80,000 | ₦150,000 |
| DC/AC cables | 4mm², 10mm², 16mm² | ₦60,000 | ₦120,000 |
| Circuit breakers + SPD | DC fuse, MCB, RCCB, SPD | ₦45,000 | ₦90,000 |
| Installation labour | 2–3 day install | ₦120,000 | ₦250,000 |
| Total | ₦1,365,000 | ₦2,130,000 |
Note: real quotes often land above these midpoints when you add contingencies like battery cable runs >5m, roof reinforcement for mounting, or a change-over switch for grid integration. Always budget 10–15% above the quoted price for unexpected site requirements.
What Drives Price Variation
Two quotes for the "same" 3kVA system can differ by ₦800,000. Here is why:
- Battery type: Lithium LiFePO4 costs 3–4× more per unit than tubular lead-acid. This is the single biggest price driver across a system.
- Panel brand: Genuine Tier 1 panels (Jinko, Canadian Solar, LONGi) cost 15–25% more than unknown brands but come with 25-year performance warranties.
- Inverter brand: Deye costs 15–25% more than Felicity for the same kVA. Both are hybrid — the difference is build quality and local support.
- Cable quality: Cheap installers cut costs on cable — using undersized wire that runs hot, causes voltage drop, and is a fire hazard. Proper solar cable (4mm² for panel runs, 16mm² for battery) costs more and is worth it.
- Installation quality: Rushed installs skip proper earthing, surge protection, and cable management. Proper installation includes earthing rod, DC/AC surge protection, and labelled terminations.
Red Flags in a Lagos Solar Quote
- No itemised list — just a total price for "complete 3kVA system"
- Panel brand is unlisted or you cannot find it on the manufacturer's website
- No mention of mounting frames or cable sizes
- No circuit breakers or surge protection in the list
- Price is 40%+ below other quotes for the same spec — something is missing or counterfeit
- Cash only, no receipt, no physical shop address
How to Get a Fair Price in Lagos
Get exactly three itemised quotes from installers with physical addresses (not just WhatsApp numbers). Compare line by line — panel brand and wattage, battery brand, type, and Ah rating, inverter brand and kVA, cable sizes, warranty terms. Ask each installer for their NEMSA certification number. Do not make a decision based on the total price alone.
