Replicating the calculation of "Subarray 1 DC power gross (kW)".

Hi SAM staff.

I was trying to replicate the calculation of the " Subarray 1 DC power gross (kW). " by doing

Subarray 1 DC power gross (kW) = Nº modules × Area of each module × Subarray 1 Module efficiency (%) × Subarray 1 POA total irradiance after shading soiling reflection (IAM) (W/m2)  /  1000

But the results seem to not match in any hour. Is there something wrong with my calculation?.  I'm using 1530 bifacial modules with an area of 2.5832 (m²) each.

Below is an image showing the columns resulting from the simulation.

Thank you in advance.

Hi Dario,

In my testing, my calculation is very close to SAM's results. The difference is likely due to rounding errors.

For example, see the attached .xlsx and .sam files.

Best regards,
Paul.
