JavierGV Posted December 5, 2016 Share Posted December 5, 2016 The evaluation of the "Losses" of a PV array (as for the definition of the normalized performance ratio), takes as starting point the energy which would be produced if the system worked always at STC conditions (1000 W/m², 25°C, AM1.5). In the loss diagram of PVsyst we can see:1) the PV loss due to irradiance level: the loss due to operating irradiance (instead of 1000 W/m²).2) the PV loss due to temperature: the loss due to operating temperature (instead of 25°C STC). But there is no PV loss due to operating AM level (instead of AM1.5).Why? Link to comment Share on other sites More sharing options...
