A case is a complete set of input data and results. A project file contains at least one case. SAM uses tabs to display each case in the file, analogous to the way Excel displays worksheets in a workbook.

SAM highlights the active case name:

When there are more cases than can be displayed, click the ellipses to list the cases that are not visible:

Why Use Cases?

By creating more than one case in a file, you can easily compare the assumptions and results of different analysis scenarios. For example, you could use cases to compare the cost and performance of a residential photovoltaic system in several locations by defining a separate case for each location, or you could compare a utility-scale photovoltaic and concentrating solar power systems.

Tip. You can use the inputs browser to compare values of input variables in different cases.
