"Solar is too expensive." We hear it every week — usually from someone spending ₦150,000 a month on petrol or diesel. So let's settle the argument with actual numbers, using realistic 2026 prices.
The Contenders
- Option A: 10kVA diesel generator — ₦2,800,000 purchase price.
- Option B: 5kVA hybrid solar system with 10kWh lithium storage — ₦5,500,000 installed.
Yes, solar costs nearly twice as much upfront. Now watch what happens after the purchase.
Running Costs: Where Generators Bleed You Dry
A 10kVA diesel generator under moderate load burns roughly 1.5–2 litres per hour. Run it just 8 hours a day:
- Fuel: 12 litres/day × ₦1,100/litre = ₦13,200 per day
- Monthly fuel: ≈ ₦396,000
- Servicing (oil, filters, plugs) every 250 hours: ≈ ₦40,000/month averaged
- Yearly running cost: ₦5,200,000+
The solar system's running cost? A panel wash a few times a year and a periodic checkup — under ₦100,000 per year, and nothing at all if you're on a maintenance plan.
The 5-Year Scorecard
- Generator: ₦2.8M purchase + ₦26M running ≈ ₦28,800,000 — plus noise, fumes, and at least one engine overhaul.
- Solar: ₦5.5M installed + ₦0.5M maintenance ≈ ₦6,000,000 — silent, clean, and still under warranty.
Over five years the generator costs nearly five times more. Even running the generator only 4 hours daily, solar still wins by more than ₦7 million.
The Costs Nobody Puts in the Spreadsheet
- Health: generator fumes are linked to respiratory illness — a silent killer in dense estates.
- Noise: your family sleeps through the night on solar. No 6am pull-start.
- Security: no fuel storage, no fuel theft, no midnight trips to the filling station during scarcity.
- Property value: homes with installed solar increasingly command premium rents in Abuja.
The Smart Play: Hybrid
Many of our customers keep their existing generator as a rainy-season backup and let solar carry 90%+ of the load. The generator that used to run 8 hours a day now runs 8 hours a month — and the savings fund the solar system in under two years.
