Project Background
Nigeria faces frequent grid instability and power outages, making reliable electricity a critical challenge for residential properties. High dependency on diesel generators also drives up operating costs and maintenance efforts.
The client, a villa owner in Nigeria, sought a clean, quiet, and sustainable alternative to secure round-the-clock power for their home without being held hostage by an unreliable public grid.
Customer Needs
- Uninterrupted 24/7 power supply for a medium-sized villa, including air conditioning, lighting, appliances, and entertainment systems.
- Drastic reduction of grid dependency to avoid disruptions during blackouts.
- A robust system that can handle local weather conditions and occasional high temperatures.
- Long-term energy cost savings and minimal maintenance requirements.
- A scalable and future-ready solution that can accommodate potential load increases.
ELECNO Solution
We designed and installed a custom villa solar power system featuring:
- 40 pieces of 550W high-efficiency monocrystalline solar panels (total 22kWp) to maximise energy harvest under Nigeria's solar irradiance.
- A 20kW hybrid inverter with built-in MPPT and seamless grid-to-battery transition.
- A 50kWh lithium-ion battery bank for substantial overnight storage and backup during extended grid failures.
- Intelligent energy management software that prioritises solar consumption, stores excess energy, and automatically switches to battery backup when the grid drops.
- Weather-resistant mounting structures and surge protection tailored for local conditions.
Project Outcomes
100% reliable power: The villa now enjoys stable, uninterrupted electricity day and night, even during prolonged grid outages.
Near-zero grid reliance: Daily grid purchases have dropped by over 85%, with the system covering almost all household loads from solar and stored energy.
Significant cost savings: Diesel generator usage has been virtually eliminated, reducing fuel and maintenance expenses substantially.
Quiet and clean operation: The system runs silently with zero local emissions, improving comfort and environmental footprint.
