NSRDB and SAM -- A Clarification of the Relationship between the Tools

Forums: 

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.
