hello. I am modeling the grid connected PV plant about 50MW and I am wondering how to calculate "PV loss due to temperature" in PVsyst. As i know, "PV loss due to temperture" is the factor related to the module temperature which would be calculated with the ambient temperature, heat loss factor and temperature coeffiicient for module. So, I think if tilt is increased, "PV loss due to temperature" would be increased because of the increase of global incident. However the result of simulation I got didn't have that kind of trend. the result of simulation (PV loss due to temperature) tilt 20° 21° 22° 23° 24° 25° 26° 27° 28° 29° 30° PV loss due the temp. -1.28% -1.29% -1.29% -1.30% -1.30% -1.30% -1.30% -1.30% -1.30% -1.29% -1.29% PV loss due the temp. is increased steadily accorting to tile to 28°, but more than 28°, the loss is dropped. I don't know the reason why the loss is dropped in spite of increase of tilt. please let me know the correlation between "PV loss due to tempertrue" and tilt. thank you.
