The following are the output variables for a particular PV surface.

May I ask how is the Generator Produced DC Electric Power [W] calculated?

It seems it is not equal to:

Surface Outside Face Incident Solar Radiation Rate per Area [W/m2]

x Surface Area [m2]

x Generator PV Array Efficiency

The PV generator is specified in Honeybee as the following:

The hourly PV output for one day is:
