Fabian Blatter Posted April 2 Share Posted April 2 Hello, when simulating a single axis tracker with stowing strategy is the wind direction taken into account? When stowing with an angle not equal to 0, the PV panel should face the direction the wind is coming from. Is PVsyst considering that when simulating the stowing strategy? I'm using PVsyst 7.4.

Agnes Bridel Posted April 2 Share Posted April 2 Hi Fabian, The wind stow strategy in PVsyst is currently a very simple model where the trackers are put into stow position when the wind speed is above a certain threshold. In version 7.4, this strategy is only available for tilted trackers and horizontal N-S trackers. The wind speed direction is also not taken into account at the moment since this information is not easily available. We are working on improving this feature and should allow more flexibility to this function in future releases. Best, Agnes Link to comment Share on other sites More sharing options...
Fabian Blatter Posted April 2 Author Share Posted April 2 Thank you Agnes! Can you tell me which way the tracker is facing in stow position? Is it towards the sun or always to the East respectively West (in the case of a horizontal N-S tracker)? Link to comment Share on other sites More sharing options...
Agnes Bridel Posted April 3 Share Posted April 3 Hi Fabian, When the wind stow is activated, you can define the stow position - the angle between the tracker and the rest position. Best, Agnes Link to comment Share on other sites More sharing options...
