Interpreting Shading Loss in 8760s for PV Capacity Testing

[Jherche]

Hello,

 

I am running a PV capacity test per ASTM2848-13 and it is important to filter out any data where shading is present. I am struggling to interpret the shading losses per the 8760 outputs. 

 

I have FShdBm and ShdBlss. Is there shading whenever FShdBm is < 1 and whenever ShdBlss > 0? Should I use any other 8760 outputs or is this sufficient?

 

Thanks.

Hello,

Indeed filtering out these two variables should be sufficient to remain compliant with the ASTM 2848-13 standard
