The amount of hours from sunrise to sunset is equal to the total sunlight hours in a 24 hour period. Similarly, peak sun hours are the amount of total sunlight hours in a 24 hour period that are strong enough to provide power from being captured by a solar panel. Not every hour of sunlight delivers the same amount of energy resources. The sunlight at sunrise does not provide as many resources as the amount of sunlight mid-day. Thus, looking at the average peak sunlight hours for Bear River City is valuable for calculating your solar needs.

Sunlight hits the earth directly at the equator. This is why the equator has a latitude of zero degrees. The latitude of Bear River City is 41.6. Knowing the latitude of Bear River City 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.

Throughout the day the sun obviously moves throughout the Bear River City 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

There are more variables than latitude that can change average peak sun hours. Weather patterns and geography will influence solar insolation that reaches your system. Thick grey storm clouds for example will block out a lot of the sun to the point where there may be no peak sun hours in the middle of the day when the sun is usually very powerful. Trees and mountains can deflect the sunlight, so be sure your solar panel is selectively placed.

For Bear River City the number of average daily peak sunlight hours for a fixed solar panel is 6.5 hours. If you are using a more efficient 1 or 2-axis panel then the number will increase to 8.4 hours for a 1-axis panel and 8.5 hours for a 2-axis panel.
