Different number of Mesh Faces and Results

Hi all,

I would like to seek your help in the following issue. I have a group of surfaces that I am analyzing by entering the grid size as the longest length of the edge of the surface because I would like to get the same surfaces after the analysis to filter based on KWh values.
However, after the analysis, I get the same number of meshes but a higher number of results or points due to which I cannot filter out the surfaces properly.

Could you please help me out with this problem? I would really appreciate it.

Thank you so much!
