  1. I have a question I have a pv sol premium 7.5 can I upgrade to 2016 with the same license ?
  2. Ok this so much helpful but now I have another question , is this curves can be edited in the user created panels , and if possible how can this be achieved ?
  3. Dear all, Hope this message finds you all well I would like to ask , what factors affects the specific yield for the same location . as what I did try is to choose different panels and compare the specific yield . and some results were just making no sense some panels were have better efficiency , better temp. coefficients and still have lower specific yield So it will be helpful if one of you guys try to explain what really affects the specific yield calculation Best regards, Ahmad Elghobashy
  4. And what is exactly meant by area utilization ratio ? and how is it calculated ?
  5. Dear sir, Thanks for your reply . now what I need to know is the area of the ground use , can I get this area from the program and how , and this area should be = the generator area + restricted areas + maintenance paths because in the report I only get the generator area , but it would be helpful if I know the whole area Regards, Ahmad Elghobashy
  6. Hello madams and sirs, How can I calculate for the total land or roof area used ? and not the pv generator area ? what I mean is the total area including the panels cleareance and the eadges and the walkways in between strings Regards, Ahmad Elghobashy Egypt
  7. Hello, My name is Ahmad Elghobashy from Egypt I do have a question and don't know what to do , and I think maybe you can help I have a string of 20 modules of Jinko solar panels JKM 310Wp now from the data sheet the open circuit voltage is 45.9 V So the total string open circuit voltage is 918 V now in the system check I get 1018 V So the max. allowed open circuit is exceded but I don't know why there is a 100 V over the stated in the data sheet Best regards, Ahmad Elghobashy Egypt

  9. I have a project where in one roof , I have two types of installation one array should be mounted while the other is roof parallel . And I did the first from mounted assembly , then when I add panels from module coverage I get an error messeage saying that I can't use both on the same mounting surface what is the solution for that problem ? Or how can I cobine both on one roof ?
