Kano gets 28% more sun per panel than Lagos.
Sellers size on "five peak sun hours". Satellite data puts a fixed array in Lagos at 3.63 kWh per kWp per day, falling to 3.15 in the wettest month. Port Harcourt sits at 3.43. The package that carries a home in Kaduna leaves Lagos on the generator in August.
ZEUS sizes per city and, where it matters, on the worst month.

Every result shows its formula.
Sourced. Dated. Practical.
Prices are observed across sellers and reported as dated ranges. Yield comes from the Global Solar Atlas. Tariffs come from NERC orders, fuel prices from named reports on named dates. Every formula is printed so a quotation can be checked line by line. ZEUS sells nothing and installs nothing.
