harwinder333 Posted August 26, 2019 Share Posted August 26, 2019 1. Total voltage mismatch loss = Mismatch loss (voltage drop due to wiring resistance)+ Mismatch loss (voltage due to PV array temperature variation)+ Mismatch loss (Specified voltage distribution tool)e.g. 0.05%+0.51%+0.34%2. What is the use of option "wires and results"? Is it total result? Link to comment Share on other sites More sharing options...
André Mermoud Posted August 29, 2019 Share Posted August 29, 2019 I don't see how you have evaluated these loss percentages. By the way the mismatch losses are not cumulative, as each of them implies a displacement of the Pmpp on the I/V curve. You have a detailed tool for studying the mismatch between strings: In the system dialog, "Detailed Losses > Module quality-LID-Mismatch", you can press "detailed study". Here you can press F1 for a description of the Mismatch problematics. Usually the mismatch between strings (in voltage) is extremely low. Link to comment Share on other sites More sharing options...
