  1. Hi Hizir, Thank you for your reply. I see the Regular and Bold for Airal Unicode MS fonts in the C:Windows>Fonts folder. Fortunately, my company installed an update for PVsyst this morning and now I can view and print reports again. Hopefully it will stay this way! Thanks again, Ben
  2. Following a recent update, I'm no longer able to produce a complete report in PVsyst. As you can see in the attachment, the pages are missing most information. Please let me know what I should do to restore the report functionality.
  3. Hi Linda, Thank you for your reply! Can you also please clarify what your estimate is for structure shading factor based on my post (10% or 40%)? And isn't your comment on mismatch effect related instead to structure shading factor. i.e. where you wrote, "as the current in a string is the current in the worst cell, if the structure covers x% of one cell, the shading effect will be x% for the concerned string. For example, the loss may be reduced by a factor of 2 if the structure covers half a cell (or two half cells)." Thanks again, Ben
  4. Can PVsyst please comment on this post? I have the same question and want to add that there are a lot of sources that recommend calculating the structure shade factor simply by taking the ratio of the width of the racking (or torque tube) on the rear side by the length of the module (assuming it's in portrait orientation). My concern is that this is not taking into account the electrical effect of shading a row of cells that is in series with the rest of the cells, i.e. the current will be reduced in the entire module if you shade just a single row of cells. So the calculation should be the width of the row of cells divided by the width of the racking or torque tube, correct? This is in line with PVsyst's instructions, "the current in a string is the current in the worst cell, if this mechanics covers x% of one cell, the shading effect will be x% for the concerned string. This loss may be reduced by a factor of 2 if the mechanics is covering half a cell (i.e., the shade is distributed on 2 cells). " In summary, following these instructions, assuming the racking above shades 40% of the row of cells behind it, even if it's only 10% of the length of the module, would the Structure Shading Factor be 40%? Or 10%?
