Based on historical San Antonio, TX data, solar panels that are tilted towards the equator at an angle equal to the latitude will produce the maximum solar energy output in San Antonio.[1]
San Antonio has an average monthly Global Horizontal Irradiance (GHI) of 4.76 kilowatt hours per square meter per day (kWh/m2/day), which is approximately 3% greater than the average monthly Direct Normal Irradiance (DNI) of 4.64 kWh/m2/day. [1]
Solar installations in San Antonio that are always titled at the latitude of San Antonio (Average Tilt at Latitude or ATaL) average 5.21 kWh/m2/day, or about 9% greater than the average monthly GHI of 4.76 kWh/m2/day and approximately 12% greater than the average monthly DNI of 4.64 kWh/m2/day. [1]
Solar Energy Glossary
Global Horizontal Irradiance (GHI)
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 (DNI)
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 (ATaL)
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.
