Hello Michael, I would like to clarify my question. Does the simulation calculate the PR while taking into account the system’s location and the fact that the inverter experiences early clipping? I’m asking because, according to the system monitoring data, I can see a difference in PR between the simulation results and the actual performance on site. Another question — regarding the panel temperature: Does the simulation consider the temperature variations of the panels? Since when the temperature rises, the panel’s output decreases, this factor also affects the system’s PR. In addition, does the PR value shown in the report reflect the PR including temperature effects, or should a PR corrected value be presented in the report instead?

Hi Michael, First of all, thank you for your response. Unfortunately, in both cases, the system has already been installed, and I don’t have the option to replace the equipment. It might be worth considering adding this function in future versions.

Dear PVsyst Support Team, I am currently working on two ground-mounted PV sites, and I have encountered two different issues during the simulations: Inverter clipping time – In one of the sites, the inverter reaches clipping quite early, around 11:30 AM. Is there any way within the simulation settings to define or adjust the specific time when inverter clipping occurs? Module temperature limitation – In another site, the module temperature exceeds 45°C, which significantly reduces the system’s performance. Is it possible to set or limit the module’s maximum temperature within the simulation parameters? Thank you in advance for your assistance.
