Abuja Residential: 7.2 kWp Solar + 15 kWh Battery
A family home in Abuja ends its dependence on a diesel generator with a compact solar and battery system
System Type
Residential solar + storage
Project Goal
Reduce diesel dependence and improve uptime
Coverage
Abuja, FCT
The Challenge
This family home in Abuja was almost entirely reliant on a diesel generator for daily electricity. With grid supply averaging just 4–6 hours per day, the generator ran for most of the household's waking hours. All told the home was spending about ₦255,000 a month on power: around ₦55,000 in prepaid units for the hours the grid was on, roughly ₦175,000 on diesel (about 90 litres), and another ₦25,000 on servicing and repairs. Frequent outages disrupted work-from-home routines and the children's schoolwork, and the constant generator noise and fumes had become a serious quality-of-life issue.
The Solution
InfraSol deployed a 7.2 kWp rooftop array of Jinko 620W monocrystalline panels, paired with an Aurora Solar 6 kVA hybrid inverter and a 15 kWh Aurora Solar LiFePO₄ battery bank. The system was sized specifically to cover the household's full daytime load (lighting, fans, electronics, and a small AC unit) with enough battery reserves to carry essential loads through the evening. The entire system was purchased outright at ₦5.6M.
The Outcome
Generator usage completely eliminated. The unit has not been started since installation
About ₦255,000 a month that used to go on diesel, generator repairs and prepaid units now stays with the household
Payback of 1.5–2.1 years at September 2026 diesel prices, with 20+ years of savings ahead

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.
