Does anyone have the data for Tesla/Panasonic 325W Panel being produced in NY? Does SAM/NREL expect to be adding that data to the Module section?

Hello,

SAM's module and inverter libraries use data from databases managed by the California Energy Commission (CEC). If that module is added to the CEC library, then it will eventually end up in SAM. We update the libraries in SAM each time we release a new version, so there may be a lag between the time the item is added to the CEC library and when we add it to SAM.

See this post for information about how to model modules and inverters not in SAM's libraries:

sam.nrel.gov/node/69678

Best regards,
Paul.

Thanks. However, I am not sure that I know how to translate the needed fields SAM from the CEC database. Below is what I am translating the CEC information to SAM's (on the right after the "=="), let me know any are wrong or if the scale selected is incorrect.

Hello,

That mapping of parameters names looks correct to me. When you enter the data in SAM, be sure to specify the correct units for the temperature coefficients using the dropdown lists.

Best regards,
Paul.
