The performance metrics are values that SAM calculates from the hourly performance model results and, for some variables such as capacity factor, the system specifications.

After running a simulation, SAM displays the performance metrics on the Results page:

Metrics table

Data Tables, under Metrics (with additional variables under Single Value)

Graphs, with the Single Value option for X Value, or with parametric or other analysis options that involve input variables with multiple values.

Note. SAM may use slightly different names for the metrics, depending on the model options and where it displays the metric. For example, "annual AC energy" may also appear as "annual energy."

SAM displays different metrics depending on the performance model you are using.
