Hello again! Sorry that I did not explain correctly. The default configuration which better fits my installation is the 'free mounted with air circulation on both sides'. What I was trying to say is that with this option losses due to temperatura seem to be too low. Would it be a good option to choose one of the other default configurations, so that the resulting losses due to temperatura are not too low (so the PR I guarantee is not too agressive), despite the fact that the one which better fits my configuration is the 'free mounted' one? This would be a strategy in order to be not too agressive with the guarantees of PR and production. Does it make sense?

Hello everybody, I would like to ask your opinión regarding thermal losses. I am working on an offer for a Client, who is asking for guarantees related to production and PR. Usually I choose the default option 'Free mounted modules with air circulation' because is the one which better fits my configuration. However, the resulting losses due to temperature are quite low (at around 7%) and so PR is higher than expected. Do you recommend me to choose a less dissipative option ('semi-integrated' or 'fully back insulated') in order to be less agressive with the guarantees? Do you recommend me specific values for Uc and Uv instead of the three default options? Which is the most sensible option for an offer with which we do not want to be very agressive with the guarantess we provide? Thanks in advance and regards. Patrik.

Hello everybody! This is my first time in the forum. I hope to be able to describe my doubts correctly and that someone can help me. My doubts are related to 'Show Sizing' in the dialog 'System'. My understanding of the explanation given by 'help' option is the following: on the one side, as long as Array Power values are below the Inverter DC Pnom, for the reason that the inverter is not limiting, purple and green steps are the same. On the other side, for Array Power values higher than Inverter DC Pnom and, due to the fact that the Inverter does limit, the energy at inverter output is lower and so the purple steps are slightly below green ones. However, I do not understand the graphs of plenty of my simulations (please find attached the file): - ¿Why is the purple arrow in the origin? ¿why is not located at a value slighty higher than 2100kW (at its DC limit)? - ¿How is posible that purple steps remain above green ones? (I expected them to be the same until Inverter DC Pnom is reached, and never the purple ones above). - It seems that for Array Power values higher than Inverter DC Pnom (at around 2100kW), the graph is as I was expecting, that is to say, with purple steps slightly below Green ones. ¿But which is the interpretation of the graph before this point? Thank you very much in advance. Patrik.
