A 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 six 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.
