Re: CEC modules

Hello, 

I asked a similar question a while back, maybe that will help you out?

Hey hey,

I am currently working with PVlib to do a solar energy estimation of an actual setup. This will be done by comparing the modelled power outputs with the measured power outputs of the system. The module implemented in this PV system are stored in the CEC database and are: Trina Solar TSM-400DE09.08, Trina Solar TSM-395DE09.08. Unfortunately they are not available to acess via pvlib.pvsystem.retrieve_sam('CECMod‘) but are listed in the csv-file which I downloaded from https://github.com/NREL/SAM/blob/develop/deploy/libraries/CEC%20Modules.csv 

First of all, I am wondering if someone knows why they are available on the local csv-file of CEC module library for Fall 2022 release but not accessible when pvlib.pvsystem.retrieve_sam('CECMod‘) is used. Secondly, I have tried to access the information of the PV modules via cec_modules_local.iloc[14224]. But this also gives me an error as soon as I try to plot the power output of the model, see attachment. I tried to convert the data frame in order to get the correct type of parameters and data but it did not work. I solved the problem in the end by creating a dataframe with all the parameters from the csv-file via copy & paste basically, which is not the nicest solution.

Is someone familiar with this problem and can maybe help me out? Thank you very much, I would appreciate it.

All the best,

Kim
