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 Upsala 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 Upsala is 45.8. Knowing the latitude of Upsala 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.

Since a fixed solar panel is set in one position it is ideal to place it at an angle that will expose the panel to the most sunlight throughout the year. This angle is generally the same angle of your latitude which is 45.8 for Upsala. You do not need to strategically place a 1-axis or 2-axis panel as much as you do a fixed panel. A 1-axis panel follows the movement of the sun during the day. Additionally, a 2-axis panel also adjusts for the suns various positions in the sky throughout the year.

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.

The average daily peak sunlight hours in Upsala, Minnesota is 4.6 hours. Use this number when trying to calculate your solar needs in Upsala. As you can see above, if you were to use a 1-Axis or 2-Axis panel then the daily average would increase to 6 hour and 6.4 hours, respectively.
