P50-P90 Gross and net value

[Sada]

Hi,

I went through the articles listed prior, but could not find an answer. How can we get the P50 gross and net value. 

Alternatively, the P50 value which we get at the end is it the gross value or net value.

 

Thank you.

Regards

It depends on the weather file you are using. What is your weather resource? If it is a standard TMY file, it is a P50 estimate. Whether it is gross or net depends on if you have included all loss factors for your system, i.e. AC losses, transformer losses, night and auxiliary loss, degradation, etc.
