How to Find a Trusted Solar Installer in Nigeria (2026)
Why Finding the Right Installer Matters
Solar installation in Nigeria is an unregulated market. Anyone can call themselves a solar installer with no training, no certification, and no accountability. The consequences of a bad installation include:
- Battery dying within months due to wrong charge settings
- Inverter failing due to incorrect wiring
- Solar panels underperforming due to poor positioning or shading
- Fire hazard from undersized cables or poor connections
- Fake components installed at the price of genuine ones
- No recourse when things go wrong — installer disappears
⚠️ In Nigeria, at least 40% of solar system problems reported to Dr. Solar are caused by installation errors — not component faults. The installer matters as much as the equipment.
Step-by-Step: How to Find a Trusted Installer
Any serious installer will have a portfolio of completed installations they can show you — photos, addresses of past clients willing to be contacted, or video evidence. An installer who cannot show you previous work has no track record.
Ask specifically: "Can I speak with one of your recent clients?" A trustworthy installer will say yes without hesitation.
Before hiring, ask a few technical questions. You don't need to know the answers yourself — just observe how confidently and specifically they respond.
Good questions to ask:
- "What battery type setting will you use on the inverter for a Pylontech battery?"
- "What charge voltage do you set for a 48V lithium system?"
- "How do you calculate the cable size for the DC connection?"
A trained installer answers these immediately and specifically. A fake one gives vague answers or becomes defensive.
A trustworthy installer provides a written quote that lists every component separately — brand, model, capacity, and unit price. This allows you to verify market prices independently and confirm you're getting what you're paying for.
Refuse any installer who gives you a single lump-sum price with no breakdown. They are almost certainly hiding the component costs because they are cheaper than what you're being charged.
Before the installer begins work, verify every major component:
- Check battery serial numbers on manufacturer websites
- Weigh batteries — fake ones are always lighter than spec
- Check inverter serial number on manufacturer portal
- Run Dr. Solar's diagnostic on the battery before it is installed
Ask specifically: "What happens if something goes wrong in the first year?" A trustworthy installer offers a workmanship warranty (at minimum 6 months, ideally 12 months) covering their labour and settings. They should also be available for follow-up visits if needed.
Get this in writing before payment.
