Alvarado Solar Power Information & Peak Sun Hours
Solar Green Energy Summary for Alvarado, Texas
Fixed Tilt Sunlight Hours: 5.7 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 Alvarado 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 Alvarado has a latitude of 32.4. 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 Alvarado 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
Weather is one of the major culprits that will cause inconsistent total peak sun hours for any given day. The sunrise and sunset will always be predictable every day, but the weather is hard to predict and cloud coverage can greatly diminish the efficiency of a solar power system on any given day. On the bright side, a location that is known to have cloudy weather a majority of the year could have unexpectedly more sunny days, so it can go both ways.
We can take the latitude of Alvarado and use that number to know the amount of total sunlight hours in the region from sunlight to sunset and estimate that with a fixed solar panel, Alvarado will receive 5.7 average peak sun hours per day. This number can be increased to 7.4 hours by using a 1-axis tracking mount, or 7.5 hours from a 2-axis tracking mount.
