Real Risks of Going Solo (Without a Pro)
Let’s not sugarcoat this.
Here are the top mistakes beginners dey make when dem try install solar system without any electrician: skipping a proper solar power installation guide and ignoring the correct step-by-step solar system installation process.
- Wrong polarity – batteries explode or swell
- Undersized wires – causes overheating and fire
- Loose terminals – inverter shuts off randomly
- No earthing – risk of shock during storms
- Overloading – damages batteries and inverter
We’ve seen it all—burnt fuse boxes, melted wires, ₦100,000 batteries fried in 2 weeks. That’s what happens when you rush to install a solar system without proper planning. Take your time, follow the process, and protect your investment.
Still want to do it yourself? You can.
But you’ll need to do it the right way.
Do You Need Certification to Install Solar System in Nigeria? Here’s the Truth

So—you don’t need a certificate or permit for a personal, off-grid solar system in your home or apartment.
But: if you want to install solar systems commercially or for others, you’ll need to be licensed and certified.
Step-by-Step Guide to Install Solar System Safely — Even If You’re a Beginner
So you’ve decided to go the DIY route. Awesome.
Here’s a basic checklist to keep things legal and safe—especially if you want to install solar without an electrician in Nigeria.
Before You Install Solar System: Design It on Paper First Like a Pro
Before lifting a screwdriver, map your solar system:
- Calculate your daily energy needs (lights, TV, fridge, fans)
- Size your battery bank (using our solar power calculation guide)
- Match your inverter capacity (e.g., 1.5kVA, 2.5kVA)
- Choose panel wattage based on Abuja sunlight (e.g., 100W x 4 panels)
This will save you money and prevent overload nightmares later.
How to Install Solar System Safely — The Importance of Using the Right Tools
A smart installer always uses proper tools:
- Digital multimeter (₦7,000–₦10,000)
- Cable crimpers and cutters
- Battery terminal wrench
- Insulation tape and wire sleeves
- MC4 connectors (for panel wiring)
- Fire extinguisher (just in case, boss)
Not using the right tool? You’re not saving money—you’re setting traps.
Install Solar System Correctly: Always Follow the Proper Wiring Flow
Here’s the safest connection order:
Solar Panel → Charge Controller → Battery Bank → Inverter → House Load
NEVER connect panels directly to an inverter.
And don’t connect live wires without fusing or isolating.
Make sure your battery-to-inverter wires are thick enough (e.g., 25mm² or 35mm² for 24V).
Install Solar System Safely: Why Grounding Matters — Yes, Even in Abuja
Earthing is often ignored in Nigeria, but it’s crucial:
- Reduces electric shock risk
- Protects from lightning surge
- Improves system stability
Use a 4-foot copper rod connected via thick copper wire to your inverter body and panel frame. Cost? About ₦3,000. Worth it? 100%.

Before going live:
- Test DC voltages with multimeter
- Power small loads (bulbs, fans) first
- Listen for sounds: humming, sparking, burning smell = RED FLAG
- Label your connections for future fixes
Then gradually add your fridge, freezer, or TV.
Pro tip: Let your system run idle for 1 hour—no load. Observe everything.
Real Case Study: Emeka’s Mistake in Lugbe, Abuja
Emeka bought a ₦300,000 DIY solar kit.
No electrician. Just YouTube and vibes.
He forgot to:
- Fuse the DC side
- Use thick enough wires
- Earth the inverter
Result?
- 3-day old battery swelled and died
- Inverter began tripping at night
- Lost ₦125,000 before calling a real tech
He now says:
“If I had spent ₦10k more for proper wiring tools, I’d have saved over ₦100k.”
Moral of the story? DIY doesn’t mean “do without sense.”
