Solar Panel System for Home in Nigeria: What to Buy & How to Install
With unreliable electricity supply, rising fuel prices, and frequent blackouts, more Nigerian homeowners are switching to solar panel systems for home. A well-installed solar system can power your lights, TV, fans, fridge, and even air conditioners—without noise, fuel, or monthly electricity bills.
This guide is designed to help you understand everything about solar panel systems for your home: components, costs, installation, and what to expect in 2024 and beyond.
What Is a Solar Panel System for Home?
A solar panel system is a complete setup that captures sunlight and converts it into electricity to power your home.
🔋 Key Components Include:
- Solar Panels – Convert sunlight into DC electricity
- Inverter – Converts DC to AC power for your appliances
- Battery – Stores excess power for nighttime or cloudy days
- Charge Controller (MPPT/PWM) – Regulates charging to protect the battery
- Mounting Kit + Cables – For rooftop installation and wiring
Types of Solar Panel Systems for Homes
✅ 1. Off-Grid Solar System
- Works independently of PHCN/NEPA
- Ideal for remote/rural homes
- Requires batteries for 24/7 power
✅ 2. Grid-Tied Solar System
- Connected to NEPA
- No batteries required
- Powers home during the day, reduces PHCN bills
✅ 3. Hybrid Solar System
- Combines solar + grid + battery
- Works even if NEPA is down
- Most recommended for urban homes
Benefits of Installing Solar Panels at Home
| Benefit | Impact |
|---|---|
| ✅ Reduced power bills | Slash NEPA costs or eliminate them completely |
| ✅ Backup during outages | Power stays on even during blackouts |
| ✅ No fuel needed | Unlike generators, solar is 100% renewable and silent |
| ✅ Low maintenance | Panels last 25+ years with minimal care |
| ✅ Increases home value | Solar-equipped homes are more valuable and future-proof |
How Much Solar Power Do You Need?
It depends on your daily energy consumption. Here’s a quick guide:
| Appliances | Watts | Estimated Usage Hours/Day | Total Wh/Day |
|---|---|---|---|
| 5 LED Bulbs | 50W | 6 hours | 300Wh |
| 1 Standing Fan | 70W | 10 hours | 700Wh |
| 1 LED TV (32”–43”) | 90W | 6 hours | 540Wh |
| 1 Laptop + Router | 50W | 8 hours | 400Wh |
