  1. Hi PVSyst Team,

    I'm designing TFT exported from PVCase to PVsyst.

    1. The trackers imported have no bays. Is this because the modules are connected on the same string? The longer tables are 4string of 28 modules and the shorter ones are 3 strings of 28 modules.  

    2. If this is correct, the treatment is same as non-TFT approach using according to module string and Module layout result for the electrical approach? 

    3. Partition guidelines?

    Thank you,

  2. Hi PVSyst Team,

     Since my scene is too large, I created a smaller scene exactly for 1 central inverter.  Base from the module layout I have this values.

    QUESTIONS: 

    1. Following the guide from PVSyst Help screenshot above then = 29.4% - 9.3% = 20.1% (Is this the fraction for electrical effect that I will be using in the Nearshading ?)

    2. I also did a 100% Fraction for electrical effect but I'm not sure about the definition of "regular (row-to-row)". can you further explain this? By the way my scene have only tracker tables without trees or other shading. The terrain comes from PVCase. and this is the result. image.png.c4acde2f6afc744b5d53ebe01c995ff3.png

  3. Hi PVSyst Team,

    I simulated an option for Linear Shading and According to Module string. In the reports, the only difference in the loss diagram is the Sky Diffuse on the Rear Side. Can you explain why this happen? 

    The highlighted one is the " According to module string"

    Thank you very much.

  4. Yup that solved it. Thanks Michelle. 

     

    Another inquiry in the same project.
    Is it due to the csv file downloaded that I have varying pitch? This one is from the orientation tab saying my pitch is at 5.84m. (see image on the left) then my field properties on the near shading is 7.0m. The correct one is at 7m and 32.8% GCR.

  5. What should be the correct approach for the partition of half-cut cell modules in tracker tables N-S?

    I'm using Boviet Solar  Half cut cells . Portrait. 

     

    For 1P at 4 strings (28m/s, 112 modules)

    I assumed Partitions:

    y=4 (# of string?), and

    x= 2 (since half cut modules?)Screenshot2024-09-13030906.thumb.png.fdababcbcc055768c79353c1cb458c49.pngimage.png

     

    For 1P at 3strings (28 m/s, 84 modules)? x and y.

     

    I've read the PVsyst help regarding partitions but I'm still at lost. Kindly help.
