if i am not wrong . I cant also express what i have understood due improper sentence
Please answer with yes or no. If not why??
These points are expected or not
1) zenith and azimuth gives sun direction right ya wrong??
2) altitude give sun elevation angle right ya wrong??
3)for dual axis tracker i need to consider azimuth along x dir that circular and altitude angle y direction for vertical motion.
The respective angle for day is attached in below . it relevant to one day. ?? Please let me know whether i calculated right or wrong.
formula taken from herehttp://www.susdesign.com/popups/sunangle/altitude.php
You need to know your current position and the current time. You need to calculate the direction of the sun at that position and time, for example as an azimuth angle and zenith/elevation angle. You need to position your actuators to point your device in that direction. You need to repeat this periodically so that the device tracks the sun as it moves. I'm sorry if it sounds patronising to explain something so basic after you've spent this much time working on a solar tracker, but from the way you keep asking about it I'm not at all sure you have grasped the concept.
current time : is calculate from RTC
current position?: still not confirmed
i considered azimuth and altitude angles to determine position.
since actuator as no feedback , i am using inclinometer to adjust angle from reference 0~360 degree and 0~90 degree.
