Hello,
I am trying to model a simple PV system in PySAM.
I used Pvwattsv8.default("PVWattsNone") and then set some inputs in the code. For example, I set the system capacity as 4kW, while the default value is 100,000 kW. After executing the model, the result shows the annual energy output for a 100,000 kW system.
It seems the code executes the model for default values, although I set different values.
I have no idea what's wrong with it.
I copy my code here:
import PySAM.Pvwattsv8 as PV
pv_model = PV.default("PVWattsNone")
pv_model.SolarResource.solar_resource_file = 'path'
pv_model.system_capacity = 4.0 # System capacity in kW
pv_model.SystemDesign.dc_ac_ratio = 1.2 # DC-to-AC ratio
pv_model.SystemDesign.array_type = 0 # Fixed array type
pv_model.SystemDesign.tilt = 30 # Tilt angle in degrees
pv_model.SystemDesign.azimuth = 180 # Azimuth angle in degrees (South-facing)
pv_model.SystemDesign.gcr = 0.4 # Ground coverage ratio
pv_model.Losses = 5
pv_model.execute()
annual_energy = pv_model.Outputs.annual_energy
capacity_factor = pv_model.Outputs.capacity_factor
energy_yield = pv_model.Outputs.kwh_per_kw
