Dear

 

Can I make a calculation with a sun tracking system?

 

 

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

Will it be possible to do "backtracking" on the single axis tracking arrays?

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
  
• one-axis with vertical rotation axis
  
• two-axis
  

If there are any wishes left, let us know

 

Kind regards,

Martin

 

what does surface usage factor refer to

 

thanks

Rob

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

thanks for the diagram

 

I have Premium 7.0 release 5

I also have 2017 on a different computer, I haven't realised i had different software on different computers.  it is on the 2017 version sorry my mistake.

 

Rob

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

Hi everyone,

please see our new tracking videos here:

Hi,

Where is tracking options  in pv sol premium 2021?

Kind regards!

 

Hi Dinko,

on the page PV Modules there is a dropdown-menu to select tracking:

Please also refer to our online help: https://help.valentin-software.com/pvsol/2021/en/pages/pv-modules/#tracking

Hello!

Is there already a simulation for the modules tracking the sun?

What the presentation looks like with this type of modules?

I want to depict a plot of land with panel following the sun and trace their effectivenes.

Thanks in advance!

Hi Go green BG,

within PV*SOL 2D this is possible, the presentation looks just about the same but it is possible to list the gains from tracking.

If you have further question, feel free to ask!

Best regards,
Frederik

Hello again! I'm trying a tracking system on the ground. How do I set the dimensions of an irregularly shaped property and the distance from its boundaries?

Is there a video tutorial for a project with trackers?

Thanks in advance!

Hello Go green BG

I am not quite sure if I understand your question correctly, but if you are trying to achieve a sun tracking system within PhotoPlan I must disappoint you. This is not possible.

Kind regards
Frederik

Hello Go green BG

Не съм съвсем сигурен дали разбирам правилно въпроса ви, но ако се опитвате да постигнете система за проследяване на слънцето в PhotoPlan, трябва да ви разочаровам. Това е невъзможно.

I am trying to stake this type of tracker (from the picture). Is it possible for pv sol to arrange the panels on a property with set dimensions?

And again I ask: is there a video tutorial for a 2D project with trackers?

Yes. You do not have to paint a certain area since the calculations for 2D are not dependent on any positioning within a space. So I´d say your settings are correct.

I am afraid there is none, no.

Is there already an option for tracker construction in 3d?

Hi Go green BG,

at the moment there are no plans to implement tracker construction in the 3D Designer.

Hello I have scheme design using N/S Single axis trackers and note there is now more data in the Bi-Facial modelling. I searched but cannot find the reference points used of the "Shading by Assembly system".

Default is at 10%, how is this calculated?

 

Hello HamishL

Sorry for the belated response, your request slipped through.

As far as I'm concerned it is not calculated. It is our default assumption of shading due to the mounting system.
Depending on the system you do use to incline your modules, feel free to adapt the fraction of irradiation which reaches the backside.

Kind regards
Frederik

Hello again! I need help. The construction of today's project is tracker. The axis along which it moves is east-west. Starts at 55 degrees and stops at -55 degrees. I am attaching a photo. How do I set the parameters correctly in a 2d design to calculate system performance? 

Rotation Axis Incline  - ?

Rotational Angle of Opening - ?
