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.
