• Quality of vineyards depend on many aspects that are determining the terroir, such as declination of the terrain, orientation to the cardinal points, time of exposure to the sun, altitude and many more
• In these analysis we were researching obscuration and angle of rays under which they fall on the terrain
• Our analyses were made from observation of these days: 1) Spring equinox, 20th of March 2012 2) Summer solstice, 21st of June 2012 3) Autumn equinox, 23rd of September 2012
• In each day we were considering three main day times, namely 2 hours after the sunrise, the midday and 2 hours before the sunset
• 2 hours after the sunrise
Equinox 20th of March, 23rd of September
• Midday
Equinox 20th of March, 23rd of September
• 2 hours before the sunset

• 2 hours before the sunset
Solstice 21st of June
The average values of sunlight rays angle fall and sum of shadows made from 20th of March, 21st of June, 23rd of september
in these daytimes 2 hours after sunrise, midday, 2 hours before sunset
