Energy Yield calculation - Detailed PV model

Dear Paul,
 
I do not fully understand how the Energy Yield (kWh/kW) is calculated.
 
According to the info in the Help section, it is as follows: Energy Yield (kWh/kW) = Net Annual Energy (AC kWh) ÷ Nameplate Capacity (DC kW)
 
But in the model I’m working on, I get an Annual Energy (year 1) of 143,080,528 kWh and the DC nameplate capacity of the systems is 62,496 kW. So the Energy Yield should be 2,289 kWh/kW. Instead, in the Summary page it displays 2,368 kWh/kW.



Thanks in advance.

Best regards,

Ana

Hi Paul,

Yes, the Nameplate DC Capacity in the System Design page is 62,496 kW.

Please, find attached the .sam file.

Thanks a lot.

Best regards,

Hello

I am having the same. What the energy yield considers as calculation?

Hello,

I am encountering the exact same problem as mentioned above. The annual AC energy 624'455 MWh
The nameplate DC is 261 MWp

This should give a Specific yield of 2392.5 kWh/kWp, but the summary gives 2557 kWh/kWp, which doesn't make sense to me.

Do you know where this comes from?

Thank you,
Kind regards,
A. Magnus
