JaroslawKonopka Posted September 21, 2018 Report Share Posted September 21, 2018 Hi All My new house has orientation: 247°, 67° with 2 oriels (Gaube in german), that means that I can also use small roofs on Gaube with orientation 157° Due to orientation of house I have during the day walking shadows and the position of the moduls is very critical. I created 3D model and made shadow simulations and found out best configuration(one from few, but relatively easy to install) with minimized shadows on moduls. It seems that quite OK is: - 247° - 18 moduls -67° - 10 moduls - 157° - 2 x 2 moduls. In my system I want to use: - moduls 310W G4.1 Q.Cells (already ordered) - optimizers SE P370 (already ordered) - inventer SE9K Currently no akku; I will update the system in the future. I need support of PVSol expert and somebody with more PV experience. I plan to connect all moduls in 1 string with optimizers and SE9K. I made such simulations (with model of usage: 4000kWh family+4000kWh heating system) and got results: P=9467kWh pro Year (PV Generator Energy (AC Grid) 954.34lWh/kWp (Spec.Annual Yield) 5.2% (Yield reduction due to shading) I would lik eto ask any experience person for help and suggestion how to connect all my moduls on my 3 roofs(247/67/157) to get maximized power pro year (PV Generator Energy (AC Grid). In the attachment there is pdf file with modul/shadow distribuition on my roofs. Unfortunatelly,teh simulation project file is larger than 9.77MB and I can not uploaded. The link to the project file (google drive) is given below: https://drive.google.com/open?id=17ajHnpp7UPQsi_09mKT56f1CcAtf2L-H I would be very greatfull for any suggestions and improvements.
