PRTemp (PR Weather corrected)

[daniel.luzzi]

Greetings,

By analyzing the documentation provided in Performance Ratio PR - PVsyst documentation, it says that the Weather-corrected Performance Ratio uses the following equation:

PR (corr) = E_Grid / ( PNomPV * Σ hours ( GlobInc / GRef * (1 - muPmpp * (Tarray - TArrayWeighted))

Where the TArrayWeighted is described as "Array temperature average on the whole year, weighted by the GlobInc value. This is named TArrWtd in the program."

 

When analyzing the monthly PRTemp in the simulation report, I need to be sure that for the monthly result it is used the weighted average annual temperature and not the monthly temperature.

Yes, the monthly PRtemp values are calculated using the array average yearly temperature, as mentioned in the help.
