Galena Park Solar Power Information & Peak Sun Hours
Solar Green Energy Summary for Galena Park, Texas
Fixed Tilt Sunlight Hours: 4.8 hours per day
1-Axis Tilt Sunlight Hours: 7.4 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 less than peak sun hours. Looking at the average peak sun hours in Galena Park throughout the year can help you better estimate the amount of solar panels you will need to power your business or home.
The latitude of the location is important for measuring peak sun hours. The latitude determines how much overall sunlight there will be in a day. With a given latitude, time and date, one can accurately determine when sunrise and sunset will occur. Areas with latitudes closer to the equator will have a more consistent range of solar insolation throughout the year. Whereas areas closer to the poles will have a greater variance during the summer and winter months due to their higher latitudes.
Throughout the day the sun obviously moves throughout the Galena Park 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
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.
By taking the latitude of Galena Park 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 Galena Park one can expect close to 4.8 average peak sun hours per day. With a 1-axis tracking mount you would get 7.4 hours per day, and 7.5 hours per day with a 2-axis tracking mount that tracks the sun everywhere in the sky.
