SUN PATH

SUN PATH DIAGRAMS FOR SHADING ANALYSIS

Photo voltaic is very important to find the exact path of sun at any region in particular time duration with complete information of shade shape and size because Photo voltaic is very shadow sensitive. This diagram gives complete knowledge about the signs of obstruction in specifics periods of time. It give the time when area will be in shade and sun will be back of obstruction.

  Solar altitude and azimuth angles for 40◦ latitude

There are a lot of method and product to find out the hurdles on the way of sun. One of the good and cheap way is to use of your geometry box tools with a typical compass but it’s your effort. By using plumb bob 

,protector and compass. Azimuth angle is measured from the compass and altitude angle from plumb bob.

Magnetic Declination or Deviation

 According the phenomena compass should point towards magnetic north but they point true north this difference called magnetic declination or deviation.

Example

Here in it show that due to trees the sun light not reach through November to January at the time of 8 :30 AM to 9 :30 PM approximately 1 hour.

The shade projection cause the sun light lost round about 3 o clock.
