Falcon Heights Solar Power Information & Peak Sun Hours
Solar Green Energy Summary for Falcon Heights, Texas
Fixed Tilt Sunlight Hours: 5 hours per day
1-Axis Tilt Sunlight Hours: 7.5 hours per day
2-Axis Tilt Sunlight Hours: 7.9 hours per day
If you put your solar powered math calculator in your backpack it will turn off from the lack of sunlight needed to power the device. As you slowly open your backpack and begin to let sunlight in, the calculator will eventually turn on when the amount of sunlight is enough to power the calculator. Similarly, peak sun hours refer to the hours of they day where the sunlight is strong enough to power a solar panel. This is different from total sunlight hours, which is simply the amount of hours in a day when there is any sunlight.
The latitude at the equator of the earth is zero degrees. This is where sunlight strikes the earth most directly. Due to the earth's curved shape, sunlight hits at a various angles depending on location. As latitude increases, the further you are located from the equator and more variance you see in sunlight hours. The latitude of Falcon Heights is 26.6.
Throughout the day the sun obviously moves throughout the Falcon Heights 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.
Since we know the latitude of Falcon Heights we can take the average amount of total sunlight hours and estimate that with a fixed solar panel there would be an average of 5 peak sun hours per day. 7.5 hours per day with a 1-axis tracking mount that tracks the sun from sunrise to sunset, and 7.9 hours with a 2-axis tracking mount that tracks the sun everywhere in the sky.
