Lekki Residential — 10 kWp Solar + 20 kWh Battery
A Lekki homeowner powers their entire household on solar with a high-capacity system and dual battery storage
System Type
Residential solar + storage
Project Goal
Reduce diesel dependence and improve uptime
Coverage
Lekki, Lagos
The Challenge
This Lekki homeowner was determined to achieve complete energy independence. With a 4-bedroom household running multiple air conditioning units, a large fridge-freezer, and a full suite of electronics, monthly electricity and diesel costs were punishing. The family was tired of rationing power — deciding which rooms got AC, which devices to unplug, and constantly monitoring fuel levels in the generator.
The Solution
InfraSol installed a 10 kWp solar array optimally angled for Lagos's solar irradiance, connected to a Deye 11 kVA hybrid inverter capable of handling the household's full load including air conditioning. Two 10 kWh LiFePO₄ battery units (20 kWh total) store enough energy to carry the home from sunset through the night. The system was sized for near-total independence — no compromises on comfort. Purchased outright at ₦8M.
The Outcome
Entire household now runs on solar — air conditioning, appliances, lighting, and electronics
Zero generator dependence with battery reserves covering evening and overnight loads
Full payback projected at 4.2 years, with the system delivering pure savings for 20+ years after

Financial Payback Analysis
System Lifecycle & Quality
Premium Jinko Solar Panels: Industry-leading panels with 25-30 year lifespan and 25-year performance warranty. Expect 80-85% efficiency even after 25 years of operation.
High-Quality Lithium Batteries: Advanced lithium battery systems designed for 10+ years of reliable operation. Battery replacement typically needed after year 10-12, maintaining your savings throughout the system's life.
Note: These projections model realistic degradation for premium systems (~0.3% panel + ~0.5% battery per year), normal operating conditions, and regular maintenance. Actual performance may vary based on usage patterns and environmental factors.
