Midwest Solar Power Information & Peak Sun Hours
Solar Green Energy Summary for Midwest, Wyoming
Fixed Tilt Sunlight Hours: 5.8 hours per day
1-Axis Tilt Sunlight Hours: 7.1 hours per day
2-Axis Tilt Sunlight Hours: 7.5 hours per day
The average amount of peak sun hours in a day is a different and more useful number as it relates to solar panels than total sun hours. Total sun hours are exactly what you would expect; the total amount of hours that the sun is out during a 24 hour period. Peak sun hours, on the other hand, are the total number of hours in a day where the sunshine is strong enough to to be absorbed and used by solar panels. Sunlight early in the morning or late at night is often not strong enough to count toward peak sun hours. Because of this, total sun hours will always be more than peak sun hours. Looking at the average peak sun hours in Midwest throughout the year can help you better estimate the amount of solar panels you will need to power your business or home.
The equator has a latitude of zero while Midwest has a latitude of 43.4. Any city located on the equator will receive the most sunlight throughout the year because the sunlight arrives at a perpendicular 90 degree angle to the earth at the equator. The further you are from the equator the more your daily sunlight hours can vary.
Throughout the day the sun obviously moves throughout the Midwest 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
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.
By taking the latitude of Midwest one can get a close estimate of the amount of average peak sun hours per day for the geographical area. It varies with technology and the type of solar panel mount you use, but for a fixed mount solar panel in Midwest one can expect close to 5.8 average peak sun hours per day. With a 1-axis tracking mount you would get 7.1 hours per day, and 7.5 hours per day with a 2-axis tracking mount that tracks the sun everywhere in the sky.
