If you're running a generator in Nigeria, you already know the pain: fuel prices climbing every month, constant service calls, oil changes, spark plugs, and that endless rumbling noise. But exactly how much is your generator really costing you?
The True Cost of Running a Generator
Let's break down the monthly cost of a typical 3.5kVA generator running 8 hours daily:
- Diesel/Petrol: ~₦3,500/day × 30 = ₦105,000/month
- Engine Oil: ₦5,000/month
- Maintenance: ₦10,000/month (averaged)
- Generator Replacement: ₦8,000/month (based on ₦300K every 3 years)
Total: ~₦128,000/month or ₦1,536,000/year
Solar System Cost Comparison
A 3.5kVA solar system costs ₦1,800,000 — approximately the same as 14 months of generator running costs. After that, your electricity is essentially free for the next 20+ years.
5-Year Savings Comparison
- Generator (5 years): ₦7,680,000
- Solar (5 years): ₦1,800,000 (one-time)
- Your savings: ₦5,880,000
The numbers speak for themselves. Solar energy isn't just better for the environment — it's dramatically cheaper than running a generator when you look at the full picture.
