Kiana Solar Power Information & Peak Sun Hours
Solar Green Energy Summary for Kiana, Alaska
Fixed Tilt Sunlight Hours: 2.6 hours per day
1-Axis Tilt Sunlight Hours: 3.5 hours per day
2-Axis Tilt Sunlight Hours: 4.4 hours per day
Looking at the average peak sunlight hours in Kiana 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 Kiana, Alaska.
The equator has a latitude of zero while Kiana has a latitude of 67.0. 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.
A tracking mount will increase the average peak sun hours for a solar power system. Think about a panel that is tracking the sun in the sky vs a panel that is fixed and not moving: you will see a higher efficiency ratio of productions. A 1-axis mount will track the sun from East to West from sunrise to sunset and move on a single axis of rotation. A 2-axis mount will track the Sun from East to West the same as a 1-axis mount would, but it will also track the angle of the sun in the sky as it slowly varies season to season. A 2-axis mount is more necessary in high latitude regions where the angle of the sun in the sky changes dramatically between each equinox.
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.
For a fixed mounted solar panel in Kiana, meaning that the solar panel will not track the sun in the sky, once can expect about 2.6 average peak sun hours per day. A 1-axis mount would increase this number to 3.5 hours per day because the panel would be facing the sun throughout the day. A 2-axis system that tracks the sun in the sky every day of the year would get approximately 4.4 hours per day in Kiana.
