SOLAR ENERGY RESOURCE IN NIGERIA Nigeria receives a lot of sunshine all year round due to its geographical location (close to the equator). On average, each square meter receives about 2,000 kWh per year. (Irradiation = 2,000 kWh/m²/year). This is more than enough to produce energy for all Nigerians. This energy can be used to generate electricity, heat, etc. PEAK SUN HOURS The term “peak sun hours” (psh) is often used to describe the solar irradiation (the amount of solar energy) on a given day. 1psh = 1000W/m²per for an hour. If a day has five peak sun hours (5 psh), this is equal to 5 kW/m² for that day. In order to better understand “peak sun hours”, we can try to imagine that the sun rises immediately to a maximum power of 1000W (as if it were switched on to “high noon” like a lamp) and is allowed to stay so for the number of peak sun hours available to that region and is then suddenly “switched off” again. This is a very important parameter used in designing a solar power s...
