Looking at the average peak sunlight hours in Butler is a valuable number for determining your solar power setup. Peak sunlight hours are only the hours a day in which the sunlight is strong enough for the solar panels to do their job. Not every hour of sunlight was created equal. For example, solar panels do not provide much use during early sunrise and sunset, and therefore you should not look at total hours of sunlight in a day, but instead focus on peak sunlight hours. Using this number will provide a much better estimate of your needs for setting up panels in Butler, Kentucky.
The equator has a latitude of zero while Butler has a latitude of 38.8. Any city located on the equator will receive the most sunlight throughout the year because the sunlight arrives at a perpendicular 90 degree angle to the earth at the equator. The further you are from the equator the more your daily sunlight hours can vary.
They type of solar panel you use has an affect on the average peak sunlight hours. Some panels allow for movement, so they can track the sun as it rises in the east and sets in the west, or as the seasons change and the sun's path changes. A fixed panel remains fixed and does not have the ability to rotate, whereas a 1-axis and 2-axis panel can adjust with the sun.
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.
We can use previous years of data to estimate the amount of peak sun hours in Butler. A fixed tilt mount for example will receive 4 average hours per day. For more efficiency for your system in Butler you could use a 1-axis tracking mount and increase your daily peak sun average to 5.6 hours, or even further with a 2-axis panel to get an average of 6 hours.
