User Variables

The User Variables page displays two types of special variables. Solar Advisor only uses these variables under special conditions -- you can ignore the user variables for most analyses.

General Purpose User Variables

A general purpose user variable is a variable that you can create to store values in Solar Advisor for advanced analyses. Solar Advisor stores values of user variables but does not use them in any internal calculations. You can create up to ten user variables.

One application of user variables is to enhance analyses that involve exchanging data with Excel. You can connect user variables, like other input variables, to cells in an Excel workbook. For example, you could use a user variable to convert units using a formula in Excel. You can use the general purpose user variables in parametric and sensitivity analyses.

TRNSYS System Simulation Input User Variables

The system variables are for TRNSYS programmers. You can use the system variables to store values in the Solar Advisor user interface that interact with a customized TRNSYS input deck.
