Weather Display Expected Solar value calculator

Enter the date to calculate expected solar values.

Latitude (deg) is the degrees as entered in Weather Display

Latitude (min) is the minute value as entered in Weather Display
and is the minute fine tune value on the solar control panel

Longitude (deg) is the degrees value entered in Weather Display
and is +ve if west or -ve if east

Latitude (min) is the minute value as entered in Weather Display

Solar (min) is the minute offset on the solar control panel

Timezone is the number of hours to correct local time to GMT so
west is +ve, and east is -ve.

The values given should be between your sunrise and sunset times
with solar noon at the correct time

The two solar irradiance values given are the maximum possible and
an expected value inline with the attenuation factor applied by
Weather Display.
