after all.

http://www.susdesign.com/popups/sunangle/altitude.phpI understood that altitude/ elevation gives exact position of the sun. Which i converted to my inclinometer angle

The altitude angle is calculated as follows:

Altitude =asin( [cos (L) * cos (D) * cos (H)] + [sin (L) * sin (D)])

Converted angle is

sun_pos=90-altitude; in degree.

where:

Al = Solar altitude angle

L = Latitude (negative for Southern Hemisphere)

D = Declination (negative for Southern Hemisphere)

H = Hour angle

If i am correct these relation works. let me know if i am wrong here,

2) Now we know zenith, azimuth which represent direction of sun & altitude represent sun position .

My question

1) which are angle need to be consider for the sun position for dual axis tracker

2) When to actuate the motor/actuator???

3)@ which situation limit switch are triggered for dual axis tracker.

Here i have also attached output file.
