When trying to calculate your solar power needs there are a variety of factors to consider. Panel type and location, electricity needs, number of panels needed etc. One key to figuring out the math is factoring in the average peak sunlight hours in a day. Unlike total sunlight hours, peak sunlight hours are only when the sun is strong enough to power your solar panel. Using this number can help determine your needs to power your home or business in Ralls, Texas.

Sunlight hits the earth directly at the equator. This is why the equator has a latitude of zero degrees. The latitude of Ralls is 33.7. Knowing the latitude of Ralls can help you plan for your solar panel setup, as the larger the latitude the more variance you will see throughout the year for total daily sunlight hours.

You will notice that the average peak sun hours for Ralls change based on the type of panel being used. The reason for this is quite simple. A fixed panel does exactly what it sounds like, remains fixed in one position at all times. A 1-axis and 2-axis panels have axis that allow them to rotate. The 1-axis rotates with the sun's daily east to west movement while a 2-axis also adjusts for seasonal changes.

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.

In Ralls you can look at the average peak sun hours of a fixed solar panel mount, which will be 5.6 hours. This number iis an estimate based on data of previous years. With a tracking mount in Ralls you could theoretically increase the amount of peak sun hours per with a 1-axis mount, and get 7.1 hours, or a 2-axis mount and potentially increase your average to 8.1 hours.
