cq.trac Posted August 23, 2019 Share Posted August 23, 2019 Hello All,Does anyone know what parameter in a .pan file would cause a linear vs non-linear behaviour in the max power point of a module vs temperature in the one-diode model calculated by PVsyst? I have 3 modules from the same manufacturer that behave differently, 2 modules will have a linear behaviour and their maximum power point will increase with a decrease in temperature. The last one will behave linearly up to a point (about -10C), and then its power will start decreasing with temperature instead of increasing. I've checked a few more .pan files and about 45% of them have this non-linear behavior as well, all starting to decrease in power at around -10C.Does anyone know how PVSysts decides to correct for temperature in a linear vs non-linear way? I looked at the .pan files, but no parameter really stood out that might isolate the modules with a non-linear performance, so I assume it might not have to do with the .pan file parameters and have more to do with PVSysts methods of correcting for temperature. If anyone has a potential answer to this, I'd greatly appreciate an explanationThanks, Link to comment Share on other sites More sharing options...
