Based on historical Ralls, TX data, solar panels that always track the sun throughout the day will produce the maximum solar energy output in Ralls. [1]
Ralls has an average monthly Global Horizontal Irradiance (GHI) of 5.29 kilowatt hours per square meter per day (kWh/m2/day), which is approximately 16% less than the average monthly Direct Normal Irradiance (DNI) of 6.27 kWh/m2/day. [1]
Solar installations in Ralls that are always titled at the latitude of Ralls (Average Tilt at Latitude or ATaL) average 6.09 kWh/m2/day, or about 15% greater than the average monthly GHI of 5.29 kWh/m2/day and approximately 3% less than the average monthly DNI of 6.27 kWh/m2/day. [1]
Global Horizontal Irradiance: The total amount of solar radiation that is received per unit area by a surface that is always positioned in a horizontal manner.
Direct Normal Irradiance: The total amount of solar radiation received per unit area by a surface that is always perpendicular to the sun rays that come in a straight line from the direction of the sun at its current position in the sky.
Average Tilt at Latitude: The total amount of solar radiation received per unit area by a surface that is tilted toward the equator at an angle equal to the current latitude. ATaL will often produce the optimum energy output.
