-The SSC Open Source Project repository contains the source code for the technology and financial models contained within the National Renewable Energy Laboratory's System Advisor Model (SAM).

For more details about SAM's capabilities, see the SAM website at [https://sam.nrel.gov/](https://sam.nrel.gov).
 
 You could think of SSC as the home for the algorithms behind the SAM desktop program. Most people run the code through the desktop user interface, but SSC can also be run directly using the [SAM Sofware Develoment Kit](https://sam.nrel.gov/sdk).
