Hi everybody !
I'm use to work only with the "partitioning" tool in 3D scene (+ the "According to module strings" option) and a colleague ask me why I don't use the "module layout" tool for electric calculation (I never use this one !)
So I try the module layout tool and I find some inexplicable difference in result. I have simplify the problem with a very simple simulation : 1 string of 26 modules with 1 azimuth/tilt and an obstacle shading approximatly 1 module everytime (very theoretical problem !). With this case, I expect a very low production because of the entirely part of the string is shaded.
Sim 1 : using of "Partition" in Near shadings 3D scene and the "According to module strings" option and 100% electrical losses. 1 rectangle in with and 3 in height because my module is a 3 bypass diod.
Sim 2 : using of "Detailed electrical calculation (acc. to module layout)"
The module is a Twin half cells (JKM-420N-54HL4R-BDV).
Result : PR Sim1= 0.387 and PR Sim2 = 0.797
Module layout seems to not take into account the electrical losses on the whole string.
I have an explanation but I'm not sure : does the Twin half cells let the string produce even if a whole part is shadowed ?
Thank you for your help !
