I think I follow.
I expected that
Subarray 1 DC power gross (kW) would be the unclipped output of the panels, but it looks like voltage clipping happens somewhere before that as evidenced by changing the inverter affecting the hourly
Subarray 1 DC power gross (kW) values (as seen in the attached)
. So the general flow would be,
Raw DC output from the subarrays (totaled in
Annual DC energy nominal (kWh/yr)) --> Voltage clipping produces
Subarray 1-4 DC power gross (kW) (totaled in
Annual DC energy gross (kWh/yr)) --> DC losses applied to produce
Inverter DC input power (kW) (totaled in
Annual DC energy (kWh/yr)? ) --> Power clipping, inverter efficiency, and other inverter parametersapplied to find Gross AC Output.
Is this the correct relationship between the single annual values and the hourly data? If there were no voltage clipping would the nominal DC and gross DC be the same? Or am I misunderstanding what the nominal is?
