Solar Panel Performance vs Sun Elevation
There are many factors that affect panel performance but one that is predictable is the angle of the sun striking the panel. The literature suggests that the panel watts * sin(sun angle on the panel) ...

NOCT is a standard used for solar panel specifications.
"The Nominal Operating Cell Temperature (NOCT) is defined as the temperature reached by open circuited cells in a module under the conditions as listed below: Irradiance on cell surface = 800 W/m2. Air Temperature = 20°C. Wind Velocity = 1 m/s. Mounting = open back side."
