Ideal for

  • 3–4 bedroom homes
  • Anyone now running a 6kVA petrol generator most of the day

Not recommended for: Running more than about 4.8kW at once, or three-phase machines.

What it powers

Designed for this load, with about 10 hours of backup at night. On a sunny day the panels cover about 100% of it.

How long the battery lasts

13.5 kWh

Usable of 15 kWh, without shortening battery life

12.1 hours

At your evening load (about 1kW)

6.5 hours

With everything above on at once (about 1.9kW)

Overnight: with the appliances above on their usual evening hours, a full battery carries you for about 12.1 hours, enough for the night without the generator. The panels recharge it the next day.

Watch a day on this system

The 6kVA Solar Package, hour by hour, with NEPA off all day. Watch the sun charge the battery, the battery carry the night, and see when, if ever, the generator has to start. Pick a kind of day to see how it copes when the sun is weak.

Kinds of day and how often they happen come from NASA POWER satellite data for Lagos, 2021 to 2023 (daily sunlight: best 5 kWh/m² or more, good 4–5, fair 3–4, poor 2–3, worst under 2). Panels are rated in kWp: in clear midday sun they make their rated kW, less on cloudy days. Inverters carry their full rating (1kVA = 1kW). The simulation assumes NEPA is off all day, the panels out-produce the house from 8am to 5pm with the rest filling the battery, and a home that uses most of its power after 6pm, about 12 kWh a day. The generator starts only when the battery is empty. Estimates; your engineer confirms them at the site survey.

The generator bill this replaces

A 6kVA petrol generator running 10 hours a day at half load burns about 302 litres a month. At ₦1,050 a litre that is ₦317,387 in fuel, before servicing, oil and repairs: about ₦456 for every kWh it makes. These panels make about 18.8 kWh on a sunny day, and the battery carries the evening.

Work it out with your own fuel spend
How we estimate this

Solar output: 5.58 kWp × 4.5 peak sun hours a day (Lagos) × 0.75 for heat, dust and wiring losses. Savings: the share of that output you use, valued at what the same energy costs from the generator. Generator fuel: litres per hour = 0.246 × kW drawn + 0.084 × rated kW (the standard fuel curve used in energy-planning tools), at half load, with petrol at ₦1,050 a litre and ₦15,000 a month for servicing. Small petrol sets usually burn more than this curve suggests, so real savings are often higher. Battery hours use 90% of lithium and 50% of lead-acid capacity and 92% inverter efficiency. Estimates, not a guarantee: an engineer confirms your numbers at the site survey.

Questions

How long does the 6kVA Solar Package take to install?

One working day for most homes, after a site survey. You choose your survey date at checkout.

Can I add more batteries or panels later?

Yes. The 6kVA inverter accepts additional batteries at the same voltage, and we can quote a top-up from your account.

What if my appliances are different?

Use Customise this package to swap parts, or run the solar calculator with your own appliances. An engineer checks every order before dispatch.

Is installation included in the price?

Yes. The price includes all the equipment listed, installation, commissioning and a 12-month workmanship warranty. Delivery is shown at checkout.
