The System Advisor Model™ (SAM™) is free software, and you are welcome to use it for your academic research and for commercial uses.

In documentation of your research or analysis based on SAM results, we ask that you acknowledge your use of the System Advisor Model and mention the National Renewable Energy Laboratory (NREL), which develops the software, and the U.S. Department of Energy (DOE), which funds most of NREL's work on SAM.

Here are some suggestions for SAM citations in a reference list or bibliography for a journal article and other publications. Refer to your publication guidelines for correct formatting. These examples are for SAM 2024.12.12 -- you should use the version number appropriate for your work when you cite SAM. For a list of SAM version numbers see either the SAM Download page or the SAM release notes.
