1Plasmon Posted January 25, 2013 Share Posted January 25, 2013 Can someone tell me of the assumed 2% losses on the DC side? What is the background to this assumption? I know that once the layout of an array is worked out, the copper losses could be estimated. Thanks, Al. Link to comment Share on other sites More sharing options...
André Mermoud Posted March 6, 2013 Share Posted March 6, 2013 PVsyst puts a default value of 1.5% for the array ohmic loss. It is an reasonable initial guess for your first simulations of a system. But after that you have of course to estimate your real array wiring resistance according to your own cabling options. There is a tool for helping you in this task.
