Rowena Solar Power Information & Peak Sun Hours
Solar Green Energy Summary for Rowena, Texas
Fixed Tilt Sunlight Hours: 5.4 hours per day
1-Axis Tilt Sunlight Hours: 6.8 hours per day
2-Axis Tilt Sunlight Hours: 7.6 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 Rowena throughout the year can help you better estimate the amount of solar panels you will need to power your business or home.
Knowing that the latitude of Rowena is 31.6 can be helpful for understanding total sunlight hour variance. As you approach the equator latitude approaches zero. The closer the latitude is to zero, the more consistent the daily sunlight hours are throughout the year. Total sunlight hour consistency simply makes planning for your solar power needs easier, but it is certainly not a requirement.
They type of solar panel you use has an affect on the average peak sunlight hours. Some panels allow for movement, so they can track the sun as it rises in the east and sets in the west, or as the seasons change and the sun's path changes. A fixed panel remains fixed and does not have the ability to rotate, whereas a 1-axis and 2-axis panel can adjust with the sun.
Peak sun hours are greatly affected by weather patterns. Cloud coverage is a huge factor in peak sun hours per day because heavy cloud coverage will diminish the power of the solar insolation. You can use historical climate data to estimate average cloud and weather coverage, but it will obviously vary slightly from year to year.
The average daily peak sunlight hours in Rowena, Texas is 5.4 hours. Use this number when trying to calculate your solar needs in Rowena. As you can see above, if you were to use a 1-Axis or 2-Axis panel then the daily average would increase to 6.8 hour and 7.6 hours, respectively.
