Ragy Posted September 13, 2020 Report Share Posted September 13, 2020 Dear developer team, I hope my message finds you very well, I have an question which is so urgent please. This simulation I have been doing is critical to the point that many decisions will be taken on for this already running PV system. I'm acting as a consultant for this system hence results and its explanation is important. My question is why for this project (project file and PDF simulation report are attached) the losses due to down regulation on the account of mpp voltage is so high? it represents almost 9% of the annual losses? I can see that the operating voltage is operating normally and within the range of the MPP voltage of the inverter, however there are lots of self-shading as you can see in the 3D design and the energy balance. Could this be the reason? and what's the physical explanation to these down regulation losses? does it mean for example that there are many times during the year that the operating voltage will fall behind or beyond the MPP tracking range? I don't get it. Will a minutely simulation will be useful in this case? could the inverter be the reason? Please advise as the situation is critical and thank you for your usual great support!
