Utqiaġvik Solar Power Information & Peak Sun Hours
Solar Green Energy Summary for Utqiaġvik, Alaska
Fixed Tilt Sunlight Hours: 2.9 hours per day
1-Axis Tilt Sunlight Hours: 3.6 hours per day
2-Axis Tilt Sunlight Hours: 4 hours per day
When trying to calculate your solar power needs there are a variety of factors to consider. Panel type and location, electricity needs, number of panels needed etc. One key to figuring out the math is factoring in the average peak sunlight hours in a day. Unlike total sunlight hours, peak sunlight hours are only when the sun is strong enough to power your solar panel. Using this number can help determine your needs to power your home or business in Utqiaġvik, Alaska.
Sunlight hits the earth directly at the equator. This is why the equator has a latitude of zero degrees. The latitude of Utqiaġvik is 71.3. Knowing the latitude of Utqiaġvik 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.
You will notice the difference in peak sunlight hours depending on the panel type. The more flexibility the solar panel has the efficient it can be throughout the day and the year. A fixed solar panel remains in the same position at all times. A 1-axis panel follows the sun throughout the day as it moves through the sky and eventually sets. A 2-axis panel not only tracks the daily movement, but also adjusts based on the sun's changing position in the sky throughout the year as the seasons change.
Weather is a big determinate of average peak sun hours each day. There are many aspects of weather that can increase or lessen the peak sun hours in a day in a particular location. For example cloud coverage is a crucial variable. And more importantly, what type of cloud coverage; thin scattered clouds will have less diminishing power on the solar insolation than thick rainy storm clouds. Sometimes long periods of sunny days are rare in certain locations, this would increase average peak sun hours for that time-frame
Since we know the latitude of Utqiaġvik we can take the average amount of total sunlight hours and estimate that with a fixed solar panel there would be an average of 2.9 peak sun hours per day. 3.6 hours per day with a 1-axis tracking mount that tracks the sun from sunrise to sunset, and 4 hours with a 2-axis tracking mount that tracks the sun everywhere in the sky.
