⭐ 1. Upfront Cost: Generator vs Solar
When people say generators are cheaper, they are only talking about the initial price. Yes, the upfront cost of a generator is low — but that is where the “cheapness” ends.
Generator Prices in Nigeria (2025)
Small generator (i better pass my neighbor): ₦70,000 – ₦120,000
Medium 2.5–3.5KVA generator: ₦180,000 – ₦380,000
Big 5KVA–10KVA generator: ₦500,000 – ₦2 million
Solar System Prices in Nigeria (2025)
Basic home solar (500W–1KVA): ₦250,000 – ₦450,000
Medium home solar (2KVA–3KVA): ₦700,000 – ₦1.2 million
Full home/office solar (5KVA–10KVA): ₦1.8 million – ₦5 million
Verdict:
Generators are cheaper at first — but that is only the beginning of the story.

⭐ 2. Daily Running Cost: Solar vs Generator
This is where solar completely wins.
Generator Daily Cost
If you run a generator for 5–8 hours, expect:

Oil change (every 2–3 weeks): ₦2,000 – ₦3,000
Plug/Carburetor repair: ₦3,000 – ₦15,000 occasionally
Noise & stress: Free but irritating

👉 ₦1 million – ₦2.5 million spent on fuel alone
Now compare that with solar…
Solar Daily Cost
Solar panels use sunlight — free forever.
No fuel.
No oil.
No noise.
Zero daily cost.
After installation, your running cost becomes:
👉 ₦0 per day
