Installation
Solar installation cost in Nigeria
What you pay beyond the hardware, what the installer's scope should cover, and how installed cost scales with system size.
Installed cost by system size
| System | Hardware | Installation | Total installed |
|---|---|---|---|
| 1.5 kVA starter | ₦716,000 | ₦128,880 | ₦718,148 – ₦971,612 |
| 3 kVA small home | ₦1.4m | ₦260,280 | ₦1.5m – ₦2.0m |
| 5 kVA family home | ₦2.7m | ₦485,280 | ₦2.7m – ₦3.7m |
| 10 kVA large home | ₦5.4m | ₦975,960 | ₦5.4m – ₦7.4m |
| 20 kVA small business | ₦11.1m | ₦2.0m | ₦11.2m – ₦15.1m |
| 50 kVA SME | ₦28.7m | ₦5.2m | ₦28.8m – ₦38.9m |
What the installation actually involves
- 1
Site survey and load assessment
The installer measures what you actually use and when, checks the roof structure and orientation, and looks at your existing distribution board and generator changeover.
- 2
System design
Array size, inverter rating, battery capacity and panel layout are set against your load profile and roof area. This is where over- and under-sizing gets locked in, so it deserves the most scrutiny.
- 3
Mounting and array installation
Rails and clamps go on first, then panels, then DC cabling with protection. On metal roofs this is a one- to two-day job for a residential array.
- 4
Inverter, battery and electrical works
Inverter and battery bank are mounted in a ventilated space, AC side is wired into a new or modified DB with breakers, surge protection and earthing.
- 5
Commissioning and handover
The installer tests string voltages, verifies protection, configures the inverter for your grid and generator behaviour, and hands over documentation and monitoring access.

Indicative installed cost
₦2.7m – ₦3.7m
Hardware ₦2.7m + installation ₦485,280. Generates about 14.9 kWh on an average day.
These are planning estimates. System sizes use measured Nigerian irradiance and PureWatts engineering standards; costs use the supply-and-install rates installers configure in the platform. Engineered numbers, equipment selection and a bankable financial model come from the full analysis.
