Huntsville Solar Power Information & Peak Sun Hours
Solar Green Energy Summary for Huntsville, Ohio
Fixed Tilt Sunlight Hours: 4.3 hours per day
1-Axis Tilt Sunlight Hours: 5.2 hours per day
2-Axis Tilt Sunlight Hours: 5.5 hours per day
If you put your solar powered math calculator in your backpack it will turn off from the lack of sunlight needed to power the device. As you slowly open your backpack and begin to let sunlight in, the calculator will eventually turn on when the amount of sunlight is enough to power the calculator. Similarly, peak sun hours refer to the hours of they day where the sunlight is strong enough to power a solar panel. This is different from total sunlight hours, which is simply the amount of hours in a day when there is any sunlight.
Knowing that the latitude of Huntsville is 40.4 can be helpful for understanding total sunlight hour variance. As you approach the equator latitude approaches zero. The closer the latitude is to zero, the more consistent the daily sunlight hours are throughout the year. Total sunlight hour consistency simply makes planning for your solar power needs easier, but it is certainly not a requirement.
You will notice that the average peak sun hours for Huntsville change based on the type of panel being used. The reason for this is quite simple. A fixed panel does exactly what it sounds like, remains fixed in one position at all times. A 1-axis and 2-axis panels have axis that allow them to rotate. The 1-axis rotates with the sun's daily east to west movement while a 2-axis also adjusts for seasonal changes.
Climate in your geographical region is a major factor that will influence average peak sun hours per year. If you live in a region that does not have a lot of completely sunny days, then cloud coverage will greatly influence solar insolation on any given day. Mountains and trees may also contribute to lower solar insolation if they block the sun from your panels at any given point of the day.
Since we know the latitude of Huntsville we can take the average amount of total sunlight hours and estimate that with a fixed solar panel there would be an average of 4.3 peak sun hours per day. 5.2 hours per day with a 1-axis tracking mount that tracks the sun from sunrise to sunset, and 5.5 hours with a 2-axis tracking mount that tracks the sun everywhere in the sky.
