Solar installations in Eureka that are always titled at the latitude of Eureka (Average Tilt at Latitude or ATaL) average 4.57 kWh/m2/day, or about 16% greater than the average monthly GHI of 3.95 kWh/m2/day and approximately 19% greater than the average monthly DNI of 3.85 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.
