17 of the questions Nigerians ask before buying — one air conditioner, a two-bedroom flat, a shop, a borehole pump — each answered with an inverter size, a battery size, a panel count and an installed price. Nothing here is a guess or a round number copied from a vendor: every figure on every page is produced by the same quote engine that powers our calculator, from equipment prices last checked September 2026.

Each page starts from a list of appliances with their watts and the hours they run. The inverter is sized from the peak — every appliance on at once — plus headroom, because an undersized inverter trips. The battery is sized from the average running load and the hours of backup you want. The array is sized to replace the day's energy at the peak sun hours a Nigerian roof actually gets, after system losses. Prices come from one table of Nigerian market rates, last checked September 2026, and every page shows the low, mid and high of that range rather than a single number we cannot stand behind.
