SUN PATHSun path refers to;

-- seasonal-and-hourly positional change of Sun and length of daylight as Earth rotates and orbits around the sun.

Accurate location/specific knowledge of sun path and climatic conditions essential for: economic decisions about solar collector area orientation, landscaping summer shading, and cost-effective use of solar trackers.

Sun paths at any latitude and any time of the year can be determined from basic geometry. The Earth's axis of rotation tilts about 23.5 degrees, relative to the plane of Earth's solar system orbit around the Sun. As the Earth orbits the Sun, creates the 47-degree peak-to-peak solar altitude angle difference, and hemisphere-specific difference between summer and winter.

Sun path -summer

NORTH SUN

Sun does not touches the North Side in the Northern Hemisphere- Sun rises in East and sets in West with variations in Summer and WinterNo direct solar radiation available on the Northern SideHowever, daylight available during the entire duration of the sun in North

Daylight remains uniform in North - depending on sky conditionsCoolest side with no direct SunBest for work places which require enough light but no heatNorth light is generally used in Industrial buildings/ drawing studioCourtyards should not be given in north side , as no direct sun is available here.

SOUTHERN SUNSolar Radiation available- both in Summer and WinterIn winter - Sun angle remains low- less duration of Sun- 9 hrsIn Summer-- Sun angle is high- Large duration of Sun- 14 HrsMaximum Solar radiation available on the Southern Side

In Winter Sun remains on the South for Majority of time Sufficient daylight available during the entire duration of sun Being very hot and having glare in Summer Southern side have to be carefully handled. Summer Sun being very hot and vertical- can be managed by horizontal projections. Winter Sun being low can be effectively used for making rooms warm

Southern side can be used for living and working areas- bedrooms, dining, kitchen, offices etc . In the southern hemisphere, however, it is opposite, with the windows facing the north in order to maximize solar gain
