So I got that Pmax(50oC) is the combination of Maximum Global Incident Irradiation (in clear day model) and temperature coefficient? Then my concern is how can we got the Maximum GlobInc (in clear day model) from Maximum GlobInc value, is there any relation with Clearness index Kt or Best clear day Ktcs? Maximum GlobInc value

Hi, I have some queries about inverter and array sizing. When I choose "Show sizing" button to see 2 diagram as below. In the Power sizing characteristics, there are 4 parameter: - PV array, Pnom (STC): 47500kWp - PV array, Pmax (50oC): 46476kWdc - Inverter, Pnom (AC): 42000kWac - Inverter, Pmax (25oC): 46200kWac So how can the array Pmax at 50oC (46476kWdc) be calculated? I use the muPmpp -0.4%/oC but the result is 42750kWdc? array sizing

I'm engineering a floating PV power plant. They said that putting the PV panels on the water surface can reduce operating temperature and increase efficiency as well as production, but I can't find any specific number or model to calculate these number reliably. In PVsyst, there are 3 default cases for thermal loss factor. So what is the most favorable case for floating PV plant or how can I modify these parameter to best fit with my case, anyone can help? Tks a lot :D
