Commercial office rooftop solar array at sunset overlooking the city

Commercial project · Central Business District, Abuja

Abuja office building

A rooftop hybrid system supporting offices, networking and air conditioning for a corporate tenant.

Demonstration project. Configuration is representative of MBB Energy systems; results shown are design estimates until measured data is published.

Location: Central Business District, Abuja
Customer type: Corporate office
Category: Commercial
Project capacity: 15 kVA · 15 kWp · 30 kWh

01 · Initial challenge

The situation before installation.

The building’s diesel generator carried most daytime load. Management wanted lower operating costs, cleaner power for IT systems and a quieter working environment.

02 · Energy requirements

≈ 55 kWh daily consumption across offices, servers and AC
≈ 10 kW peak load
Critical-load backup for server room and security

03 · System configuration

Inverter15 kVA three-phase hybrid inverter
Solar array15 kWp — 28 × 550 Wp modules on flat roof
Battery storage30 kWh LiFePO₄ rack storage
IntegrationThree-phase grid and diesel changeover
MonitoringRemote performance monitoring and reporting
