When weighing the decision of whether or not going solar makes sense for your roof or location, one of the first questions you may ask is “how many sunlight hours do I need for solar to be worth it?” The reason this question is important is because there is a significant range across the country for average peak sun hours. We’ll explain which states offer the best sun hour value and how much sunlight intensity in your state should impact your decision to go solar.
What is a peak sunlight hour?
The first clarification to make with the term “sunlight hour” is that it does not refer to merely hours of daylight. While many areas in Nigeria will have practically the same total daylight, some states may only average four peak sun-hours per day while others will average as many as seven.
A peak sun-hour is typically defined as an hour of sunlight that offers 1,000 watts of photovoltaic power per square meter. Peak sunlight hours describe the intensity of sunlight in a specific area. Peak sun-hours occur when the sun is highest in the sky. The number of peak sun hours will increase the closer an area is to the equator and, more generally when not in rainy season
How many sunlight hours do solar panels need?
The simple answer to this question is that there is no simple answer because a home’s suitability for solar will depend on a number of factors: roof angle, electricity bill cost and available sunlight. However, when looking at the states for solar in Nigeria there certainly is a trend: having at least 3 hours of typical peak sunlight is best for solar panels.
Which state in Nigeria solar power does not work?
As mentioned above, Solar power users will see major disparity in available sunlight depending on where they live. However, Solar power works across all states in Nigeria even during rainy season, there is no state in Nigeria without at least 4 hours of sunlight needed to run on solar home system.
