Dear Planer,

 

This will be possible in the 2D planning of the next program versions PV*SOL premium 2016 and PV*SOL 2016. In these version you will be able to select different types of tracking system with different rotation axes.

 

The programs will be released end of November and in December 2015.

 

Best regards

Dear frederik,

 

it is now possible to design and simulate PV arrays with different kinds of tracking systems:

  • Fixed systems (with the option to optimize your inclination angle for a given azimut angle)
  • one-axis north-south (with backtracking, also the option to optimize the inclination angle)

  • one-axis east-west
    Forum Tracking 02.png
  • one-axis with vertical rotation axis

  • two-axis

If there are any wishes left, let us know :)

 

Kind regards,

Martin

Hello Rob,

 

the usage factor determines how close the tracking systems are placed to each other. A usage factor of 1 means, that the distance of one tracker to the next is as long as the module width. The distance is measured from the center of one tracked module to the center of the next. So, a usage factor of 0.5 would indicate that the distance between one module and the next is twice the module width.

 

This factor mainly influences the backtracking behaviour. If modules are very close, they have to be tracked back earlier than modules that have a longer distance between them.

 

Hope that helps. If you have any further questions, please don't hesitate to ask.

 

Kind regards,

Martin

A diagram would help me understand

 

We have upgraded to Premium 7 and the tracking option has disappeared as an option.  is it still a there and hiding?

 

I have been looking at east-west tracking, so north south axis of rotation. with the modules flat (not tilted to the south).  several frame companies are claiming 20% yield improvement. with PVwatts i get the improvement but with PVsol and PVsyst I don't. 

 

Thanks

Rob

Hey Rob,

 

here is a quick sketch to illustrate the usage factor:

So, the usage factor will be (width of PV) / (distance of trackers).

 

Hope that helps. Also, east-west tracking means that the axis of rotation goes from east to west. If you want to have your trackers rotated around the north-south axis, you would use the north-south tracking option.

 

And no, the tracking option should definitely be there. Did you upgrade to the lastet version (i.e. PV*SOL premium 2017 R5) ?

 

Kind regards,

Martin

Hi Rob,

 

glad you solved the problem! So perhaps you want to update the premium 7.0 R5 version, it is now two years old... And just in case you consider doing this: we have software maintenance offers that ensure you always have the latest version of our software (and databases) without placing financial burdens on you :)

 

Kind regards,

Martin
