The energy reality

Nigeria’s electricity challenge is a cost and continuity problem.

Most properties depend on a mix of grid supply and generators. Each carries its own cost, reliability and maintenance burden. Solar addresses them together — when it is engineered correctly.

Residential solar project journey from old generator to finished system
01

Unreliable grid supply

Outages and unpredictable supply hours disrupt households, trading hours and production schedules.

02

Rising fuel costs

Since the removal of the petrol subsidy in 2023, generator running costs have risen sharply and remain volatile.

03

Higher tariffs

Tariff reviews, particularly for Band A feeders, have increased the cost of grid electricity for many customers.

04

Generator burden

Noise, fumes, servicing, breakdowns and fuel logistics add hidden cost and risk to every kilowatt-hour.

05

Voltage instability

Fluctuating and low voltage can damage sensitive equipment, compressors and electronics over time.

What changes with solar

Daytime loads run on solar, batteries carry priority circuits through outages and evenings, and the generator becomes a backup rather than a daily expense.

Solutions

Designed for how you use power.

Load profiles, budgets and risk tolerance differ between a family home, a pharmacy, an office tower and a factory. Our solutions are structured accordingly.

Why engineering matters

The benefits of a professionally engineered system.

Undersized batteries, missing protection and poor cabling are the most common reasons solar systems disappoint. A properly engineered system delivers the performance it was designed for.

How we engineer systems
01

Lower energy expenditure

Reduce generator fuel, maintenance and grid purchases with energy produced on your own roof.

02

Supply continuity for priority loads

Batteries and hybrid inverters keep selected circuits running through outages, within the designed capacity.

03

Equipment protection

Correct inverter selection, surge protection and earthing deliver cleaner, more stable power.

04

Predictable costs

A largely upfront investment replaces open-ended fuel spend that moves with pump prices.

05

Quieter, cleaner operation

Less generator runtime means less noise, fumes and fuel storage on site.

06

Documented, serviceable systems

Designs, test records and handover documentation make the system easy to maintain and expand.

Assumptions and method
  • Annual generator cost = (litres/hour × fuel price + maintenance/hour) × hours/day × days/month × 12.
  • Solar operating cost = remaining generator & grid spend × (1 − solar contribution) + O&M.
  • Annual savings = current annual spend − solar operating cost. Payback = system cost ÷ annual savings.
  • Five-year view applies the annual cost increase to fuel and grid spend, includes the system cost upfront, and includes battery replacement only if it falls within five years.
  • Excludes financing costs, generator resale value and changes in your usage.

Questions

Frequently asked questions.

Answers to common questions about sizing, batteries, cost and installation.

All FAQs
How do I know what size solar system I need?

System size depends on two things: how much energy you use in a day (kWh) and how much power you draw at the same time (kW). Our online calculator gives a preliminary estimate from your appliance list. A final design is only produced after an engineer completes a load survey at your property, because actual usage patterns, appliance condition and cabling all affect the result.

How long will the batteries last at night?

Backup time equals usable battery energy divided by the load you run. For example, a 10 kWh lithium battery with about 8 kWh usable could run an 800 W average load for roughly 10 hours. Running more appliances shortens backup time. We always state the load assumption behind any backup figure — no system can guarantee uninterrupted power under every condition.

How long does installation take?

Most residential systems are installed in one to three days after design approval and equipment delivery. SME systems commonly take several days, while commercial and industrial projects follow a project schedule agreed during design.

How much does a solar system cost in Nigeria?

Cost depends mainly on inverter capacity, solar array size, battery storage and installation complexity, and is affected by exchange rates and equipment availability. Our calculators show an indicative range based on our current unit rates and published assumptions. A formal quotation is provided after a site assessment.

Can solar work alongside my grid supply and generator?

Yes. Hybrid systems integrate solar, batteries, grid and generator supply. The system can charge batteries from the grid when available and start the generator only when necessary, reducing runtime and fuel costs. Generator integration requires correct changeover design to protect equipment.
