40kW Hybrid Solar System for Villa in Lekki, Nigeria

① Location

In Lekki, Nigeria

② Customer Type

For a luxury residential villa

③ Problem

The client was building a new villa in Lekki and planned to use both NEPA grid electricity and solar energy system.

However, the local grid power supply in Nigeria is often unstable, causing:

• Frequent power interruptions
• High electricity bills
• Heavy dependence on unreliable utility power

The client wanted a solution that could maximize solar energy usage while using the grid only as a backup source.

④ Solution

Installed a 40kW hybrid solar panel system with 76.8kWh lithium battery storage.

The system was carefully designed based on the villa’s household appliances and electricity demand, especially considering the number and power consumption of air conditioners.

The hybrid system allows the villa to primarily operate on solar energy while automatically switching to NEPA power when necessary.

⑤ Technical Specifications

Installed a 40kW hybrid solar panel system with 76.8kWh LiFePO4 battery storage.
