Installing solar with a lithium battery in Nigeria costs from ₦4.1M for a 6kVA home system to ₦48.4M for a 50kVA commercial site, in November 2026. Most homes need a 6kVA or 10kVA, which costs ₦4.1M to ₦10.2M installed. These are our published prices, with everything included.
Solar installation cost by system
Each size comes in three versions. Lite is the cheapest way in. Pro has the same panels and inverter with twice the battery. Max adds panels and battery, so the battery fills up even on a cloudy day.

What is in the price
- Panels: genuine Jinko Tiger Neo 620W, with serial numbers you can check with Jinko.
- Inverter: a hybrid, so the panels, NEPA and a generator all connect to it.
- Battery: LiFePO₄ lithium, which lasts years longer than tubular batteries.
- Mounting, cabling and protection: everything that holds the panels on the roof and connects the system safely.
- Installation and monitoring: fitting, testing, and an app that shows what the system is doing.
The other place quotes differ is quality: the class of inverter, the cells in the battery, B-grade or relabelled panels, and whether the installer fits a DC isolator, surge protection, a battery fuse and proper earthing. We go through each in why solar quotes differ.
What changes the cost of installing solar
Battery size moves the price most. A InfraSol 6kVA goes from ₦4.1M with 5kWh to ₦5M with 10kWh, on the same panels and inverter. Battery is what carries the house at night, so size it for what you run after dark.
Number of panels. More panels charge the battery faster and run more in the day. Each Jinko 620W panel is ₦134,000 on its own.
Your loads. ACs and borehole pumps decide the inverter size. A house with two or three ACs usually needs the InfraSol 10kVA. Our sizing guide works out which size fits your house.
The site. A long cable run from the roof to the inverter, a roof that needs extra support, or a site outside Lagos can add to the price. The written quote after a site survey fixes the final figure.
Adding solar panels to an inverter you already have
If your inverter is a hybrid, panels can connect straight to it. If it isn’t, you need a separate charge controller. Panels cost ₦134,000 each for a Jinko 620W; see the solar panel price guide for other sizes and the panels-per-inverter guide for how many your inverter takes. Mounting and installation are quoted after a survey.
Paying for solar installation over time
Every system can be paid 30–40% down, with the rest over 3, 6 or 12 months. The “Monthly” column above shows 12 months after 30% down. Details are on the financing page.
