The amount of hours from sunrise to sunset is equal to the total sunlight hours in a 24 hour period. Similarly, peak sun hours are the amount of total sunlight hours in a 24 hour period that are strong enough to provide power from being captured by a solar panel. Not every hour of sunlight delivers the same amount of energy resources. The sunlight at sunrise does not provide as many resources as the amount of sunlight mid-day. Thus, looking at the average peak sunlight hours for Barton Creek is valuable for calculating your solar needs.
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.
The sun moves through the sky during the day, and changes positions in the sky throughout the year as the seasons change. A fixed solar panel remains fixed in position during this movement. So, although it is effective in capturing sunlight, a 1-axis or 2-axis panel can be more efficient. A 1-axis panel tracks the sun's movement throughout the day from sunrise to sunset. In addition to that, the 2-axis panel also accounts for the movement throughout the year.
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 Barton Creek we can take the average amount of total sunlight hours and estimate that with a fixed solar panel there would be an average of 5.3 peak sun hours per day. 6.9 hours per day with a 1-axis tracking mount that tracks the sun from sunrise to sunset, and 7.6 hours with a 2-axis tracking mount that tracks the sun everywhere in the sky.
