How Much Does Solar Installation Cost in Nigeria? (2025 Guide)
Solar energy has become one of the most practical solutions to Nigeria's persistent electricity challenges. Whether you are a homeowner in Lagos, a school in Ondo State, or a business in Abuja, understanding the true cost of solar PV installation is essential before making an investment decision. This guide, prepared by Rehoteq Technologies — certified solar engineers based in Okitipupa, Ondo State — breaks down everything you need to know.
Key Factors That Determine Solar Cost in Nigeria
- Total Load (kWh/day): The sum of all your appliances multiplied by their daily usage hours. This is the single biggest driver of system size and cost.
- System Type: Off-grid systems require more battery capacity and are more expensive than hybrid or on-grid systems.
- Battery Chemistry: Lithium (LiFePO4) batteries cost 2–3× more upfront than tubular batteries but last 3–5× longer, making them cheaper over 10 years.
- Location (Sun Hours): Southern Nigeria receives about 5 peak sun hours per day, while the North receives 6–6.5 hours. More sun hours means fewer panels needed.
- Brand Tier: Economy brands (Felicity, Luminous) cost 40–60% less than Tier-1 brands (Victron, SolarEdge, BYD) but carry higher performance variance.
- Installation Complexity: Cable distance from roof to battery room, earthing requirements, and mounting structure type all affect labour cost.
Typical System Sizes and Costs in Nigeria (2025)
- 1kVA / 1kWh system: Fans, lights, phone charging — ₦750,000 – ₦1,200,000
- 2–3kVA / 3–5kWh system: Small TV, fridge, lights, fan — ₦1,500,000 – ₦2,800,000
- 5kVA / 5–10kWh system: AC, fridge, TV, office equipment — ₦3,500,000 – ₦5,500,000
- 10kVA+ / 15–20kWh system: Full home or SME — ₦6,000,000 – ₦12,000,000
Is Solar Worth It in Nigeria?
With the average Nigerian spending ₦50,000 – ₦200,000 per month on diesel generators alone, a mid-range solar system typically pays for itself within 2–4 years. After that, electricity becomes effectively free for the 20–25 year life of the panels. With Nigeria's current exchange rate and fuel prices, the return on investment for solar has never been more compelling.

Frequently Asked Questions
How many solar panels do I need for a 3-bedroom house in Nigeria?
A typical 3-bedroom house in Nigeria with fans, one refrigerator, television, lights, and phone chargers uses approximately 8–15kWh per day. This requires 4–8 panels of 400W each, paired with a 5kVA inverter and 200–400Ah lithium battery bank.
Can I run an air conditioner on solar in Nigeria?
Yes, but it significantly increases system size. A 1.5HP (1.1kW) inverter AC running 8 hours per day adds 8.8kWh to your daily load. This typically requires at least a 5kVA inverter system with 6–10 solar panels and a large battery bank. Use our calculator above to size your system accurately.
What is the best battery for solar in Nigeria?
LiFePO4 (Lithium Iron Phosphate) batteries are the best option for solar in Nigeria due to their 3,000–6,000 cycle life, tolerance for deep discharge, and safety record. Though more expensive upfront, they outlast tubular batteries by 3–5 times, making them more cost-effective over the system's lifetime.
