Solar at a glance in Nigeria
Because many Nigerians are effectively replacing a generator, the real comparison is solar-plus-battery versus fuel — and the monthly saving is often large.
| Currency | Nigerian naira (NGN) |
|---|---|
| Typical electricity rate | ₦ 250 per kWh |
| Installed cost | ≈ ₦ 1,500 per watt |
| Peak sun hours | ≈ 5.5 hours/day |
| Export / buyback | ≈ ₦ 88 per kWh |
Indicative 2026 starting points — every figure is editable in the calculator, and results depend on your own bill, roof and installer quotes.
A typical 5 kW system in Nigeria
At around ₦ 1,500 per watt, a 5 kW rooftop system costs roughly ₦ 7,500,000 and produces about 7,829 kWh in its first year at Nigeria's 5.5 peak sun hours a day. Your real numbers depend on your roof, shading, panel choice and how much power you use during the day — run your own figures in the calculator to see your exact payback, net savings and ROI.
How the solar calculator works
- Your setup. Nigeria and Nigerian naira are pre-selected, with local electricity rate, install cost and sun hours filled in. Enter your monthly bill, or size the system from your appliances.
- Your roof. Search your address or tap “use my location”, then draw your roof on the satellite map — or just type its area. We check the system fits and read local sun hours from NASA data.
- Your results. Instantly see your payback period, net savings, ROI, system size, year-1 production and lifetime CO₂ offset — compare cash vs. a loan, and download a PDF report.
Common questions — solar in Nigeria
How many solar panels do I need in Nigeria?
It depends on your electricity use, roof space and local sun hours (about 5.5 peak sun hours/day here). A 5 kW system of high-wattage panels is a common starting point for a home — enter your bill or appliances and the calculator gives your exact panel count and system size.
Does Nigeria have net metering?
Net metering is not yet widely available in Nigeria, so most systems are sized for self-consumption with battery backup rather than grid export. The appliance-based sizing option is built for exactly this.
Are there solar subsidies or incentives in Nigeria?
There is no broad national residential cash subsidy today. The economics are driven by displacing costly generator fuel and avoiding an unreliable, rising grid tariff.
How much does a solar system cost in Nigeria?
A 5 kW system is roughly ₦ 7,500,000 at about ₦ 1,500 per watt before batteries; a home backup battery bank adds significantly. Use the appliance sizer to get a system and battery size matched to your loads.
Is solar cheaper than a generator in Nigeria?
Very often, yes — once you count fuel, maintenance and runtime hours, a solar-plus-battery system usually beats a petrol or diesel generator over a few years. Size your loads in the calculator to compare.
