Editing Annual Schedules

   Previous topic Next topic  

Some input variables allow you to enter either a single value, or a series of values for each year in the analysis period defined on the Financing page. Examples of these variables are the System Degradation and Availability variables on the Annual Performance page, and the operation and maintenance costs on the system costs pages for each technology.

Variables with an annual schedule option have a small Value / Sched button next to the variable label. The variable's current mode is indicated in blue. In this case the variable's mode is Value, allowing you to define the variable's value as a single number:

SS_AnnSched-Value

You can use an annual schedule to enter annual values either by hand, typing values or pasting values from a spreadsheet or text file. You can also exchange data from an annual schedule with an Excel worksheet, see Excel Exchange for details.

To enter year-by-year values by hand:

1.Click Sched to change the variable's mode from a single value to annual schedule mode. Solar Advisor displays the Edit button.

SS_AnnSched-SchedEdit

2.Click Edit to open the Edit Schedule window.

SS_AnnSched-EditScheduleWindow

3.In Number of values, type the number of years for which you want to assign values. Typically, this number should be equal to or less than the number of years in the Analysis Period defined on the Financing page.
4.For each year in the schedule, type a value. The value should be in the same units as the variable's value.

You can also copy a row of values from Excel, or a line of comma separated values from a text file and click Paste to enter a series of values.

5.Click Accept to return to the Costs page.
