Togiak Solar Power Information & Peak Sun Hours
Solar Green Energy Summary for Togiak, Alaska
Fixed Tilt Sunlight Hours: 3.3 hours per day
1-Axis Tilt Sunlight Hours: 4.2 hours per day
2-Axis Tilt Sunlight Hours: 4.2 hours per day
Peak sun hours is arguably the most important number to consider before installing your solar panels. Unlike total sun hours, peak sun hours are calculated by looking at the amount of sunlight hours in a 24 hour period that is strong enough to be absorb by a solar panel. One way to imagine peak sun hours is to think about a solar powered calculator you owned in school. If you covered the solar panel with your finger, or tried to use the calculator in the dark, the calculator would not work. As you slowly exposed the calculator to light the calculator would eventually turn on and be usable. The same is true with peak sun hours; these are the hours that your solar panels receive enough sunlight to work. Looking at the average peak sunlight hours of 3.3 per day can help you determine the amount of solar panels you need to install to power your home or business in Togiak, Alaska.
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 Togiak is 59.1.
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.
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.
Since we know the latitude of Togiak we can take the average amount of total sunlight hours and estimate that with a fixed solar panel there would be an average of 3.3 peak sun hours per day. 4.2 hours per day with a 1-axis tracking mount that tracks the sun from sunrise to sunset, and 4.2 hours with a 2-axis tracking mount that tracks the sun everywhere in the sky.
