Based on historical Norristown, PA data, solar panels that are tilted towards the equator at an angle equal to the latitude will produce the maximum solar energy output in Norristown.[1]
Norristown has an average monthly Global Horizontal Irradiance (GHI) of 3.99 kilowatt hours per square meter per day (kWh/m2/day), which is approximately 2% greater than the average monthly Direct Normal Irradiance (DNI) of 3.9 kWh/m2/day. [1]
Solar installations in Norristown that are always titled at the latitude of Norristown (Average Tilt at Latitude or ATaL) average 4.67 kWh/m2/day, or about 17% greater than the average monthly GHI of 3.99 kWh/m2/day and approximately 20% greater than the average monthly DNI of 3.9 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.
