Jobs our engineers have designed, specified or checked

Bank head offices, residential plant rooms, rooftops and facades. Different installers, different equipment brands, the same engineering discipline behind each one.

2023 to 2026 Years covered

12kW to 100kWp Range of systems

Up to 250kWh Largest storage bank

Abuja and FCT Where the work is

Commercial

Offices, banks and buildings under construction

Row of Galaxy Energy lithium batteries and three hybrid inverters in a plant corridor

Asokoro, Abuja · 2025

100kWp array, 48kW of inverters, 150kWh of storage

Three hybrid inverters share a modular lithium bank down a ventilated corridor. Sizing it this way means capacity can be extended one module at a time, and any single unit can be isolated without dropping the building.

Array 100 kWp

Inverters 48 kW

Storage 150 kWh

Batteries LiFePO4

Africa Re rooftop array

Roof mounted array on a working head office. Rails set out around existing roof plant, with walkways left clear for cleaning and maintenance.

Type Rooftop

Client Africa Re

Year 2026

Panels built into the facade of the Afreximbank tower under construction

Abuja · 2025

Afreximbank facade, 20kWp

Solar built into the building envelope during construction. Every string and cable route had to be settled long before the panels reached site.

Array 20 kWp

Type Facade

Year 2025

Four tall battery cabinets on pallets in a plant room

Abuja · 2023

250kWh backup bank

Cabinet mounted storage sized to carry a commercial load through an extended outage, with every string fused and monitored on its own.

Storage 250 kWh

Type Cabinet backup

Year 2023

Two Deye hybrid inverters above stacked Deye lithium battery modules

Abuja · 2025

20kW Deye system, 60kWh storage

Paralleled hybrid inverters with separate DC protection per string. Labelling and cable routing done so the next engineer on site can read the system.

Inverters 20 kW

Storage 60 kWh

What these have in common

The parts of a job that decide whether it lasts

Across every system on this page, the same three things carry the most weight. They are also the three most often missing from a vendor’s quote.

Storage sized to the actual night-time load, not to a convenient round number.

DC protection and cable sizing calculated for the string configuration being installed, not a generic one.

Labelling and layout that let the next person who opens the room understand it without calling anyone.

Want the detail on one of these?

We can walk you through the sizing on a comparable system and what it cost to build.
