Nimrod Solar Power Information & Peak Sun Hours
Solar Green Energy Summary for Nimrod, Texas
Fixed Tilt Sunlight Hours: 5 hours per day
1-Axis Tilt Sunlight Hours: 7.2 hours per day
2-Axis Tilt Sunlight Hours: 8.1 hours per day
Peak sun hours are a vital measurement to understand when considering the installation of solar panels. Peak sun hours are not the same as total sunlight hours because not every hour of sunlight during the day has enough strength and solar insolation to qualify as a peak sun hour. The rule of thumb is that a peak sun hour is when the intensity of the sun that is hitting your solar panel is providing at least 1,000 watts per square meter. This is an arbitrary number, but it is a number where most solar panels will be producing an efficient output and not underperforming due to sunshine that is not strong enough or direct enough.
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 Nimrod is 26.3.
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 26.3 for Nimrod. 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.
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.
In Nimrod you can look at the average peak sun hours of a fixed solar panel mount, which will be 5 hours. This number iis an estimate based on data of previous years. With a tracking mount in Nimrod you could theoretically increase the amount of peak sun hours per with a 1-axis mount, and get 7.2 hours, or a 2-axis mount and potentially increase your average to 8.1 hours.
