Change Module Type was created by Tom Hardy

According to the manual in PVWatts V5, there are three options for module type: 1) Standard; 2) Premium; and 3) Thin film

If in this example (nsrdb.nrel.gov/api-instructions) we would like to change the module type from Standard to Premium, the manual says to write it like:
#ssc.data_set_number(dat, 'module_type', Premium)

Yet, when I add the former line when specifying the system configuration, the programs gives an error.

Thus, what should be the right way to specify a module type other than Standard?

Dear Tom,

The

module_type

input variable for the pvwattsv5 module is a number, so you should assign it a value as follows (these examples are in Python, where the hash symbol (#) indicates a comment):

# Standard (UPDATED 1/11/2017)
ssc.data_set_number(dat, 'module_type', 0)

# Premium (UPDATED 1/11/2017)
ssc.data_set_number(dat, 'module_type', 1)

# Thin film
ssc.data_set_number(dat, 'module_type', 2)

Best regards,
Paul.

Dear Paul,

I believe that for pvwattsv5 the module type values are, instead, as follows:

# Standard
ssc.data_set_number(dat, 'module_type', 0)

# Premium
ssc.data_set_number(dat, 'module_type', 1)

# Thin film
ssc.data_set_number(dat, 'module_type', 2)

Regards
