NSRDB and SAM -- A Clarification of the Relationship between the Tools
While NSRDB data can be used in SAM, they are in fact two different tools. We are unable to support the SAM tool in our Forum, however there is a dedicated SAM website.
The SAM website has its own Support Forum located at https://sam.nrel.gov/support where they can answer any questions about the SAM tool. You'll need to register for a free account on the SAM website before you can post questions in their Support Forum.
