Willow Park Solar Power Information & Peak Sun Hours
Solar Green Energy Summary for Willow Park, Texas
Fixed Tilt Sunlight Hours: 5.4 hours per day
1-Axis Tilt Sunlight Hours: 6.9 hours per day
2-Axis Tilt Sunlight Hours: 7.6 hours per day
Peak sun hours is arguably the most important number to consider before installing your solar panels. Unlike total sun hours, peak sun hours are calculated by looking at the amount of sunlight hours in a 24 hour period that is strong enough to be absorb by a solar panel. One way to imagine peak sun hours is to think about a solar powered calculator you owned in school. If you covered the solar panel with your finger, or tried to use the calculator in the dark, the calculator would not work. As you slowly exposed the calculator to light the calculator would eventually turn on and be usable. The same is true with peak sun hours; these are the hours that your solar panels receive enough sunlight to work. Looking at the average peak sunlight hours of 5.4 per day can help you determine the amount of solar panels you need to install to power your home or business in Willow Park, Texas.
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 Willow Park is 32.8.
Since a fixed solar panel is set in one position it is ideal to place it at an angle that will expose the panel to the most sunlight throughout the year. This angle is generally the same angle of your latitude which is 32.8 for Willow Park. You do not need to strategically place a 1-axis or 2-axis panel as much as you do a fixed panel. A 1-axis panel follows the movement of the sun during the day. Additionally, a 2-axis panel also adjusts for the suns various positions in the sky throughout the year.
Another reason to consider average peak sun hours is because weather can dramatically affect the day-to-day output of solar panels. It goes without saying that a dark stormy day will produce less output than a clear sunny day. Looking at a yearly average helps account for these daily variables.
Using the latitude of Willow Park along with historical data of sunlight and weather patterns we can estimate that a fixed mounted solar panel will receive an average of 5.4 hours per day in this area. That number can be increased with better technology including add a 1-axis or 2-axis tracking mount, which would increase the average peak sun hours per day to 6.9 hours and 7.6 hours, respectively.

One kWh represents the amount of energy needed by a 1000-Watt device (such as a clothes iron or a microwave oven) to operate continuously for one hour. The US Energy Information Administration reports that, on average, a kilowatt-hour costs about $.13 USD across the country.
