The average Nigerian household spends ₦25,000 – ₦80,000 per month on electricity. With tariffs increasing every quarter, solar power offers a way to lock in your energy costs for the next 25+ years. Here's exactly how to reduce your bill.
Step 1: Know Your Energy Usage
Before buying solar, you need to know how much electricity you actually use. Here's a quick calculation for a typical Nigerian home:
That's about 4.1 kWh per day — which a 2.5kVA solar system can easily handle.
Step 2: Choose the Right System Size
1kVA System — ₦250,000 – ₦400,000
Lights, fans, TV, router, phone charging. Saves ₦15,000–₦25,000/month.
2.5kVA System — ₦500,000 – ₦800,000
Above + fridge, iron, small AC. Saves ₦30,000–₦50,000/month.
5kVA System — ₦1,000,000 – ₦1,500,000
Full home coverage including 1–2 AC units. Saves ₦50,000–₦80,000/month.
10kVA System — ₦2,000,000 – ₦3,500,000
Large home or small business. Saves ₦80,000–₦150,000/month.
Step 3: Calculate Your ROI
Let's see when your solar system pays for itself:
Example: 2.5kVA System
System cost: ₦700,000
Monthly PHCN bill saved: ₦35,000
Monthly fuel saved (generator): ₦40,000
Total monthly savings: ₦75,000
Payback period: 9–10 months!
Step 4: Quick Energy-Saving Tips
- ✅ Switch all bulbs to LED (uses 80% less energy)
- ✅ Set AC to 25°C (not 16°C — saves 40% energy)
- ✅ Use inverter AC (30% more efficient)
- ✅ Turn off appliances at the socket (not standby)
- ✅ Use energy-efficient fans (BLDC ceiling fans)
- ✅ Charge phones and laptops during grid hours
- ✅ Use solar water heater instead of electric heater
- ✅ Run washing machine during peak solar hours (10am–2pm)
