The land area of Nigeria is 923,768 km2, assuming we have a 1% coverage of the area with solar panels, we will be able to harvest as much as 1854.46 x 103 Giga-watt hour (GWh).

You mean if the guys at the top ain't going into excess recurrent expenditure, we can actually illuminate Nigeria, by just planting solar panels on 1% land mass.?
This isn't funny at all. Well, let's leave the government aside.I am carried away with your calculations for the back up time. Really open my eyes to this information. 👍 to green🏃
