Going directly to my question,
I have the solar module block in SIMULINK.
When I double click on it, many parameters are displayed.
These parameters can be changed by the user. For example, Voc, Isc, Vm and Im.
There are thousands of PV modules in SIMULINK library. I want to collect some data for around 100 PV modules
for the purpose of doing some statistics about PV modules.
I want to create, for example, an Excel sheet that contains all parameters displayed in the PV module including Pm, Vm, Im, Voc, Isc, IL, Rs…etc.
These are highlighted in the following image:
I know that I can do it easily by clicking on each PV module and filling the Excel file manually but this will take a long time as I have to
see around 100 PV modules and do the filling manually which is boring and may subjected also to errors in filling the data.
Is there some easier way to get these data?
Can I get in some way these data saved in the workspace if I run the module so that I just have to copy and paste the data from each PV module to the Excel file?

You can get the parameter names and values using get_param function.
Step 1: Let us assume model name as 'test'. Then use find_system function to get the list of all the blocks in model 'test'.
BlockPaths = find_system('test','Type','Block')
Step 2: Get a list of block dialog parameters for a particular block (say 'PV Array') from the list.
BlockDialogParameters = get_param('test/PV Array','DialogParameters')
Step 3: To get the value of 'Voc' parameter, use this :
BlockParameterValue = get_param('test/PV Array','Voc')
In this way you can get the all the parameter values and if you want to do it for larger number of blocks, then implement a matlab function including all the above functions.
