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. 4.9 peak sun hours means that in Dupree on average there are 4.9 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.
Sunlight hits the earth directly at the equator. This is why the equator has a latitude of zero degrees. The latitude of Dupree is 45.0. Knowing the latitude of Dupree 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 Dupree 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.
The average daily peak sunlight hours in Dupree, South Dakota is 4.9 hours. Use this number when trying to calculate your solar needs in Dupree. As you can see above, if you were to use a 1-Axis or 2-Axis panel then the daily average would increase to 6.9 hour and 7.3 hours, respectively.
