The multiple system setup options allow you to choose which cases in the project file to combine into a system, and display the capacity and cost values for the combined system.
Select Additional Performance Outputs
List of available cases
The list of available cases shows the cases in the project file that you can combine into a single system. You must create a case for each subsystem to be combined into a single system. Solar Advisor includes only checked cases in the combined system. The list of cases corresponds to the case tabs in the project file.

This box must be checked for the system to be modeled as a combined system.
Aggregate System Variables
The aggregate system variables display values for the combined system that Solar Advisor calculates by adding values from the individual subsystems.
Combined Nameplate Capacity (kW)
The sum of the subsystem nameplate capacities displayed on the System Summary page for each subsystem. For photovoltaic systems, the nameplate capacity is equivalent to the total array capacity in DC kW. For CSP systems, it is the nominal capacity of the power cycle in kW of electricity.
Combined Heat Rate (MMBtu/MWh)
This applies only to generic fossil systems and is the sum of each subsystem's heat rate from the Fossil Plant page.
Total Direct Cost ($)
The sum of the total direct cost values displayed on each subsystem's costs page.
Total Installed Cost ($)
The sum of the total installed cost values displayed on each subsystem's costs page.
Total Direct Sales Tax ($)
The sum of the total sales tax values displayed on each subsystem's costs page.
O&M Annual Cost ($/yr)
The sum of the fixed annual operation and maintenance costs displayed on each subsystem's costs page.
O&M Annual Capacity Cost ($/kW-yr)
The sum of the fixed annual operation and maintenance costs displayed on each subsystem's costs page.
O&M Variable by Production ($/MWh)
The sum of the fixed annual operation and maintenance costs displayed on each subsystem's costs page.
