Lekki Office: 8.8 kWp Solar + 15 kWh Battery
A professional office in Lekki cuts overhead costs with a right-sized solar system that keeps the business running
System Type
Commercial solar + storage
Project Goal
Reduce diesel dependence and improve uptime
Coverage
Lekki, Lagos
The Challenge
This SME office in Lekki needed reliable daytime power for computers, networking equipment, air conditioning, and a small server. The generator was running 6–8 hours every working day, and diesel costs were eating directly into the bottom line. The business owner wanted to eliminate generator costs entirely without a massive upfront investment, and needed a system that could keep the office running seamlessly during Lagos's unpredictable outages.
The Solution
InfraSol deployed an 8.8 kWp rooftop array of JA Solar 605W panels, paired with an SRNE 10 kVA hybrid inverter and a 15 kWh Aurora Solar LiFePO₄ battery bank. The system was right-sized to handle the full office load during business hours entirely from solar, with the battery providing seamless backup during cloud cover and transition periods. At ₦6.5M outright, it was the most cost-effective way to eliminate ongoing diesel expenditure.
The Outcome
Overhead energy costs cut by approximately 70%, with diesel spend effectively eliminated
Full business continuity during grid outages. Staff and clients experience zero interruption
Payback of 1.2–1.7 years at September 2026 diesel prices, the fastest return among all five installations

Financial Payback Analysis
System Lifecycle & Quality
Tier-1 Solar Panels: Industry-leading panels with 25-30 year lifespan and 25-year performance warranty. Expect 80-85% of rated output 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.
