I’m currently working on a small rooftop photovoltaic system with a total capacity of 3 kW, consisting of 6 modules of Trina solar , 500Wp (Portrait). I’ve noticed that the electrical losses reported in my simulation seem quite significant, as shown in the attached screenshot. Given the size of this system, I’m wondering if it’s necessary to consider electrical losses in detail or if I should implement the partition define feature in PVsyst for this setup. Should I be concerned about these electrical losses for such a small system? Is partitioning a worthwhile approach for a 3 kW rooftop installation, or would generalized assumptions be sufficient? Any insights or recommendations would be greatly appreciated! Thank you! Sherry

or should i put , y:1 and x:28 , Y:1 X:14 ..? really confused

Hello! I am simulating a PV plant with strings of 28 modules. Additionally, I am using half-strings (1 x 14) and quarter-strings (1 x 7) in portrait orientation. My question is: Is the partitioning I’ve set up correct? Could you please provide an answer , as i need it badly for my project. and also i want to ask more explanation about 1row portrait and half strings in partitioning for the electrical calculation . -the firs image is for quarter-strings 1p x 7 modules -the second one is for half strings 1p x 14 modules -and the third one is for the complete strings 1 p x 28 modules this is the whole layout
