Short answer: a 5kVA inverter, 15.36kWh of lithium battery and 4 × 550W panels — ₦4.18M – ₦7.15M installed.
Clippers use almost nothing. The blower and the AC use almost everything — and a salon cannot turn customers away because light went, so this is a trade where the generator runs daily and solar is measured against a petrol bill, not against NEPA.

That is the Standard build for this load: 2600W if every appliance runs at the same moment, 8.7kWh across a normal day, and about 6 hours of backup once the sun is down. Best single estimate: ₦4,943,376.

Same load, three budgets. The inverter is sized from the full peak in every tier — an undersized inverter trips, so that is not where you save. What changes is backup hours, panel headroom and component class.
Essentials, lowest cost
Runs your essentials (lights, fans, fridge, TV) with ~4h of night backup. Heavy loads like AC only while the sun is up.
Open in calculatorWhat most Nigerian homes install
Runs everything on your list with ~6h of overnight backup. Grid or generator tops up on very cloudy days.
Open in calculatorDeye-class, full independence
Everything on your list plus headroom to add more, ~10h backup, premium inverter with app monitoring and 5–10yr warranty.

Add up every appliance as if it switched on together — 2600W here — then add 25% headroom so the unit is never running flat out, and round up to a size sold in Nigeria. That gives 5kVA. Sizing the inverter on an average instead of the peak is the single most common mistake in Nigerian quotes: the system works until the day everything is on, then it trips. Motors — pumps, fridges, compressors — also pull several times their running watts for the first second, so check the inverter's surge rating, not just its kVA.
Nothing runs at peak all night. We take 60% of peak as the real running load, multiply by the hours of backup you want, and allow for lithium only being safely emptied to about 90%. At 6 hours that is 15.36kWh — 3 modules of 5.12kWh. Because Nigerian solar sits alongside the grid rather than replacing it outright, buying backup for every possible hour is where budgets get wasted; six hours covers the usual overnight outage.
This load uses 8.7kWh a day. A Nigerian roof averages about 5.5 peak sun hours, and roughly 78% of what the panels make survives heat, wiring, the charge controller and the round trip through the battery. Divide one by the other and round up to whole 550W modules: 4 × 550W panels (2.2kWp). Harmattan dust and a genuinely overcast week will cut that — which is why the Premium build adds panels rather than battery.
A generator sized for this load would have to burn fuel for every one of these 8.7kWh, every day, plus servicing — and it still cannot run quietly at 2am. Solar front-loads that cost into ₦4.18M – ₦7.15M once. Whether that pays back faster than your current fuel bill depends on how many hours of supply you actually get, so work it out on your own PHCN hours before you commit — we will do that with you rather than sell you a bigger system than the numbers justify.
5kVA inverter, 15.36kWh lithium battery and 4 × 550W panels (2.2kWp). Installed in Lagos, Abuja or Port Harcourt that works out at ₦4.18M – ₦7.15M, with ₦4,943,376 as the realistic middle, at September 2026 Nigerian prices. The load is 2600W if everything runs at once and 8.7kWh across a day.
3 × 5.12kWh LiFePO4 modules, so 15.36kWh installed. That is sized to carry the average running load of this list for about 6 hours after dark. Drop to 4 hours and it is 5.12kWh (1 module); go to 10 hours and it is 20.48kWh (4 modules).
4 × 550W panels (2.2kWp). At the 5.5 peak sun hours a Nigerian roof averages and 78% system efficiency, that array is sized to replace the 8.7kWh this load uses each day. Each 550W module is a little over 2m long and about 1.1m wide, so count 4 of them on one unshaded roof plane before you commit.
Budget: 3.5kVA, 5.12kWh, 3 panels, about 4h backup — ₦1.37M – ₦2.6M. Standard: 5kVA, 15.36kWh, 4 panels, about 6h — ₦4.18M – ₦7.15M. Premium: 5kVA, 20.48kWh, 5 panels, about 10h — ₦6.03M – ₦10.2M. The inverter is sized from the same peak load in every tier; what you buy with the extra money is backup hours, panel headroom and inverter class.
