When facing the equator, the sun appears to move from left to right in the Northern Hemisphere and from right to left in the Southern Hemisphere. The latitude (and hemisphere)-specific solar path differences are critical to effective passive solar building design. They are essential data for optimal window and overhang seasonal design.

The solar equator is the latitude on Earth at which the Sun is observed directly overhead at midday. [1] Due to the obliquity of Earth's axis, the solar equator varies during the year, from the Tropic of Capricorn on the December solstice to the Tropic of Cancer on the June solstice.

The declination of the Sun, δ ☉, is the angle between the rays of the Sun and the plane of the Earth's equator. The Earth's axial tilt (called the obliquity of the ecliptic by astronomers) is the angle between the Earth's axis and a line perpendicular to the Earth's orbit.
