Fort Yukon Solar Power Information & Peak Sun Hours

Solar Green Energy Summary for Fort Yukon, Alaska

Lattitude: 66.5809

Sunlight

Fixed Tilt Sunlight Hours: 2.5 hours per day

1-Axis Tilt Sunlight Hours: 4.2 hours per day

2-Axis Tilt Sunlight Hours: 4.4 hours per day

It goes without saying that throughout the year the amount of sunlight in any given day is going to vary. The time of year and weather will have a strong influence on daily sunshine. Looking at the average amount of peak sunshine hours in a day during an entire year stretch is a valuable exercise when trying to determine the amount and type of solar panels you need to install to power your business or your home. 2.5 peak sun hours means that in Fort Yukon on average there are 2.5 hours a day where the sun is strong enough for solar panels to harness its energy. This number is less than the amount of total sunlight hours in a day because there are times during the day (ex. sunrise and sunset) where the sun is not strong enough to benefit solar panels.

The latitude at the equator of the earth is zero degrees. This is where sunlight strikes the earth most directly. Due to the earth's curved shape, sunlight hits at a various angles depending on location. As latitude increases, the further you are located from the equator and more variance you see in sunlight hours. The latitude of Fort Yukon is 66.6.

Throughout the day the sun obviously moves throughout the Fort Yukon sky. The suns position in the sky also changes throughout the year with the seasons. A fixed solar panel does not accommodate for these changes. However, a 1-axis panel rotates and follows the sun’s path during the day. A 2-axis panel both follows the sun’s daily path as well as the seasonal differences

The sun is a great ball of gas that rises and sets every day that the earth rotates while in orbit around the sun. Barring any major disasters this is a very predictable occurance every day. Latitude helps predict this even more, narrowing it down to the minute for sunrise and sunset. But some things aren’t as predictable that will greatly influence the efficiency of solar panels. Weather and cloud coverage for example can greatly diminish peak sun hours on any given day. Thick storm clouds will block a high percentage of the sun's rays, resulting in lower output of your solar panels. Weather needs to be factored into deciding when to use your system, or how much output one expects to get.

We can use previous years of data to estimate the amount of peak sun hours in Fort Yukon. A fixed tilt mount for example will receive 2.5 average hours per day. For more efficiency for your system in Fort Yukon you could use a 1-axis tracking mount and increase your daily peak sun average to 4.2 hours, or even further with a 2-axis panel to get an average of 4.4 hours.
