Solar & Hybrid Energy Systems

Reliable power in Nigeria means designing for the grid you actually have. We run a full load analysis before specifying a single panel, then size and install a system to match real consumption, not a generic panel count.

Our sizing methodology

Measured, not estimated

Most oversized or undersized solar installs trace back to one thing: sizing from an assumption instead of a measurement. Our process starts with data.

01

Consumption audit

We measure actual circuit-level consumption over time, not a guess from your utility bill, to establish a real load profile, including peak demand and what runs during an outage.

02

System sizing

Panel array, battery bank, and inverter capacity are sized against the measured load and your backup priorities, with headroom for future additions rather than a system that’s maxed out on day one.

03

Component selection

Hybrid inverter and battery chemistry selected for your duty cycle. Daily cycling for backup-only systems is a different spec than a system designed to reduce generator hours materially.

04

Installation & integration

Grid, solar, and generator integrated with automatic transfer, installed to the documented design with safety isolation observed throughout.

05

Commissioning & handover

Performance testing against the design spec, monitoring setup, and documented handover, so you know the system is delivering what it was sized to deliver.

System tiers

Sized to what the system actually needs to do

These are starting points for the conversation, not fixed packages. Your exact panel count, battery capacity, and inverter rating come out of the consumption audit above.

Backup essentials

Keeps critical circuits running through an outage: lighting, networking, security systems, refrigeration.

Best fit

Homes and small offices prioritizing outage continuity over full independence from the grid.

Full home or office

Sized to carry the majority of daily consumption, including air conditioning and larger appliance loads, with the grid or generator as backup rather than the primary source.

Best fit

Households and businesses looking to materially cut grid/generator dependence, not just ride out outages.

Commercial & industrial

Three-phase hybrid systems integrated with existing generator infrastructure and load management, sized against measured industrial or commercial demand profiles.

Best fit

Businesses where generator fuel cost or downtime risk justifies a larger, professionally load-managed system.

Illustrative example

What the sizing process looks like in practice

Worked in general terms to show the logic. Your actual numbers come from your own consumption audit, not this example.

Measure

Circuit-level monitoring identifies which loads run during a typical outage and for how long. This becomes the backup load profile.

Size

Battery capacity is sized to that backup load profile plus a safety margin; panel array is sized to recharge that capacity within the available daylight hours.

Verify

Commissioning tests confirm the system actually carries the backup load profile for the duration it was designed for, not just that it powers on.
