    I am attempting to use PVLIB to compute Weather-Adjusted Expected Generation hourly for a 24 hours.

    However, the function I have used is not working well and I am looking to figure out why. The data being used is from the previous day. The input to the function has GHI, Air Temp, & Wind Temp at sampling rate of every minute (so 60 samples in 1 hour).

    The other items defined are:

    • latitude
    • longitude
    • time zone
    • DC module parameters
    • inverters parameters

    The pvlib_inverter_pvwatts() function is being using to compute the data, but it is returning values that are way below the actual power generation (MWh).

    Are there any examples for this specific use case?
