Nikiski Solar Power Information & Peak Sun Hours
Solar Green Energy Summary for Nikiski, Alaska
Fixed Tilt Sunlight Hours: 3.1 hours per day
1-Axis Tilt Sunlight Hours: 4 hours per day
2-Axis Tilt Sunlight Hours: 4.2 hours per day
The average amount of peak sun hours in a day is a different and more useful number as it relates to solar panels than total sun hours. Total sun hours are exactly what you would expect; the total amount of hours that the sun is out during a 24 hour period. Peak sun hours, on the other hand, are the total number of hours in a day where the sunshine is strong enough to to be absorbed and used by solar panels. Sunlight early in the morning or late at night is often not strong enough to count toward peak sun hours. Because of this, total sun hours will always be less than peak sun hours. Looking at the average peak sun hours in Nikiski throughout the year can help you better estimate the amount of solar panels you will need to power your business or home.
Sunlight hits the earth directly at the equator. This is why the equator has a latitude of zero degrees. The latitude of Nikiski is 60.7. Knowing the latitude of Nikiski can help you plan for your solar panel setup, as the larger the latitude the more variance you will see throughout the year for total daily sunlight hours.
There are a few ways to increase average peak sun hours per year for your solar power system. One way is to use a tracking mount solar panel instead of a fixed tilt solar panel. A 1-axis mount will track the sun throughout the sky from sunrise to sunset, giving your panel a more efficient facing direction towards the sun throughout the day. A 2-axis solar panel will track the sun in the sky throughout the day, but also change and follow the angle of the sun in the sky throughout the year. Both of these axis system solar panels will produce higher average peak sun hours than a fixed solar panel.
Looking at latitude, average peak sun hours and various data can obviously help when planning for your solar power needs. The one thing you can never fully account for is changing weather. Storms, rain, cloud coverage all have an impact on solar panel capabilities.
By taking the latitude of Nikiski one can get a close estimate of the amount of average peak sun hours per day for the geographical area. It varies with technology and the type of solar panel mount you use, but for a fixed mount solar panel in Nikiski one can expect close to 3.1 average peak sun hours per day. With a 1-axis tracking mount you would get 4 hours per day, and 4.2 hours per day with a 2-axis tracking mount that tracks the sun everywhere in the sky.
