Calculation of the position of the sun in the sky for each place on earth dwg

Calculation of the position of the sun in the sky for each place on earth at any time of the day. solar path graphics. sunrise and sunset are defined as the instant when the top of the sun's disk touches the horizon. this corresponds to an elevation of -0.833° degrees for the sun. twilight is the moment immediately after sunset; characterized by a diffuse light (by extension; during the morning we speak of dawn or aurora). civil twilight is the interval of time during sunset and when the elevation of the sun is -6°. a few very bright stars and planets are visible in the sky. nautical twilight > represents the time the sun passes from -6° to -12° below the horizon; in this period the horizon and the main stars are distinguished. astronomical twilight is the time interval during sunset when the elevation of the sun is -18° below the horizon. the sky is dark and it is possible to distinguish stars above the sixth magnitude. noon in solar time occurs when the sun reaches the highest point in the sky; towards the south or towards the north depending on the latitude of the observer. azimuth indicates an angle between a point and a reference plane. it is usually the angular distance of a point from north; measure in degrees: 0° north; 90° east; 180° south; and 270° west. the height or elevation; is the angular distance from the horizon of a point on the celestial sphere; calculated as positive if it is located towards the zenith; or negative if it is located towards the nadir. the zenith; is the intersection of the perpendicular to the plane of the horizon passing through the observer with the visible celestial hemisphere; and therefore is the point above the observer's head. the diametrically opposite point is the nadir. knowledge of position and daylight hours; they allow to know the energy radiated by the sun (renewable source) in the point of the earth that we are examining. solar energy can be thermal produced by thermal solar panels or electrical produced by photovoltaic panels.
