This frame  "Internal Model result Tool" is just a tool for showing the behaviour of your PV module in any chosed GOper and TOper conditions. You can play with these values for getting the corresponding results. But this has no influence on the PV module parameters.

The reference lower temperature for the sizing of the PV array  is defned in the project's settings, frame  "Site dependent design parmeters", item "Lower temperature for absolute voltage limit".
