Hi everybody, I need to calculate the PR corrected for a PV plant ground installed and connected to the grid. I have just T back (temperature measured at the back of the module) as input data. My question is: do I need any other data to calculate the corrected PR? wind or Tamb? Using the formula of NREL in order to obtain the PR corrected, if I consider the day as time frame, G at plan of array is given by the monitoring system, Tcell typ-Tcell,i should be the difference between 25° and the daily average Tback. The daily average Tback is a simple average or is it weighted on the irradiation? Thank you very much
