Hello,
did I correctly enter the module's data into the database? Energy production results seem too low.

Module Q.CELLS Q.PEAK DUO L-G5.2 400
Manufacturer data sheet:

My PVSyst module data tabs:

I have not changed other tabs.
Exported to excel: http://pliki.domrel.pl/PVSF/qc.xls
Should I improve something???

It looks like you are missing the cell dimensions in the PAN file (122.2 cm^2 is my guess based on the 390W). Verify you have the correct power temperature coefficient Pmpp. Also your Rshunt G=0 & Rsh dont match the 390W PAN file.

The Rsh and Rshunt exponential are different in my 390W PAN file, but that's not to say yours are incorrect. As long as you have your own 390W PAN file to go off of, it should be ok.
