Hi Luca, In case you are including ground for the shadows, you have to check the layout carefully. If you are using the natural ground with the structures placen on top of it, it can happen that in some cases modules are under ground. Also in trackers, it can happen that they look fine, but when the tracker is tilted, modules get partialy underground. You should create a new surface that looks similar to how it will be after all the earth movements. Best regards, Ander.

Hello, To verify the performance of a PV site, in my company, we are doing simulations with measured meteorological data and comparing the energy exporte to grid with the measurements in the meter. With that we are avoiding any uncertainties for comparing with a precalculated PR bases on a TMY. But with bifacial modules, it is a problem, as there is one fixed value set for the ground albedo. It will be good if we can also import albedo measurements from the sensors. There are more and more sensor in PV sites, albedo, soiling, irradiance in back side of the module, and being able to import that data into simulations instead of estimating it will be good. Best regards, Ander.
