Single Axis Tracker with Stowing - Direction of stowing

[Fabian Blatter]

Hello, 

when simulating a single axis tracker with a stowing strategy and the stow angle is not equal to 0, which way is the tracker facing? 

In case of a horizontal N-S tracker: Is the tracker facing the direction of the sun while stowing or is it always facing East respectively West?

I'm using PVsyst 7.4. 

 

Best wishes

The stow position is in Phi (rotation) angle. This means that a negative angle is towards the east (as long as the axis azimuth is between -90 and 90, especially if it is close to 0).
