    Solar in Logo: sunlight, tariffs and what a system costs

    A rooftop in Logo gets about 4.4 peak sun hours a day, so every kilowatt of panels makes roughly 1,342 kWh a year. A 5 kW home system produces about 18 kWh on an average day, against roughly 18 kWh of daily demand.

    Every figure below is recalculated for the audience you pick.

    What this system returns in Logo

    A four-bedroom home running fans, fridge, TV, pumps and light air conditioning. 5 kW solar, 10 kWh battery, 4.8 kW inverter — installed at about ₦4.2m. Solar costs ₦177 a unit over its life, and 80% of demand is met without the grid.

    What it returns here

    No two buildings in Logo save the same amount. Across every viable roof modelled here, the middle half lands between 14.6 and 19.4 years to pay back, with returns of 3%–7% a year. If you already run a generator, solar starts by replacing the most expensive units you buy, so it pays back fastest; a grid-only building displaces cheaper units and takes longer.
