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.
