Littlefield Solar Power Information & Peak Sun Hours
Solar Green Energy Summary for Littlefield, Texas
Fixed Tilt Sunlight Hours: 5.5 hours per day
1-Axis Tilt Sunlight Hours: 7.2 hours per day
2-Axis Tilt Sunlight Hours: 7.4 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 less than peak sun hours. Looking at the average peak sun hours in Littlefield throughout the year can help you better estimate the amount of solar panels you will need to power your business or home.
If you’re using a fixed axis and fixed tilt solar panel, the ideal angle of the panel mount should be set at an angle equal to or close to the latitude of the location of the panel. Latitude is a valuable measurement to use when figuring how many daylight hours and the angle of the sun in the sky for your location. Since at locations with a higher latitude the sun will find itself at more variable angles in the sky throughout the year it is important to set the angle of the panel correctly and efficiently capture more peak sun hours. In the Northern Hemisphere the sun will be at lower angles in the Southern sky in the winter, and higher angles during the summer months, so the angle of the panel is crucial when trying to maximize output.
Throughout the day the sun obviously moves throughout the Littlefield 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
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.
For Littlefield the number of average daily peak sunlight hours for a fixed solar panel is 5.5 hours. If you are using a more efficient 1 or 2-axis panel then the number will increase to 7.2 hours for a 1-axis panel and 7.4 hours for a 2-axis panel.
