Maryland Office — 12 kWp Solar + 20 kWh Battery
A Lagos office in Maryland eliminates diesel costs and keeps operations running 24/7 with dual inverters
System Type
Commercial solar + storage
Project Goal
Reduce diesel dependence and improve uptime
Coverage
Maryland, Lagos
The Challenge
This commercial office in Maryland, Lagos was spending heavily on diesel just to keep the lights on and the air conditioning running during working hours. The generator ran 8–10 hours daily, and the noise was affecting staff concentration and client meetings. Unpredictable diesel prices made monthly budgeting nearly impossible, and the business was bleeding money on fuel with no end in sight.
The Solution
InfraSol designed a dual-inverter system to match the office's higher power demands: two Deye 6 kVA hybrid inverters running in parallel deliver a combined 12 kVA output. Two LiFePO₄ Power Wall batteries (20 kWh total) provide substantial storage for overnight security systems and networking equipment. A 12 kWp solar array generates more than enough energy during business hours, with surplus charging the batteries. The system was purchased outright at ₦9.5M.
The Outcome
Diesel spend completely eliminated — the generator is now a backup that hasn't been needed
Operations now run 24/7 uninterrupted, including overnight security cameras and networking
Full payback projected at 3.9 years, delivering significant net savings over the system's lifetime

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.
