Describe the bug

Cash flow send-to-Excel needs to be updated to handle ITC as array for federal and state ITC amount, percentage, and maximum value.

Current temporary solution is to display a message box and send sum of array values to Excel so Excel formulas still work, but results will not exactly match SAM.

To Reproduce

Steps to reproduce the behavior:

1. Create PVWatts / Single Owner case.
2. On Incentives page, for one of the ITC inputs, change from Value to Schedule mode and enter ITC over multiple years, e.g. [5,5,5,5,6].
3. Click Simulate.
4. On Cash Flow tab, click Send to Excel with Equations

Expected behavior

Excel workbook should handle ITC inputs as arrays:

• Correctly apply tax credit amounts to cash flow
• Correctly account for ITC effect on depreciation basis
• Correctly calculate for IBI and CBI effect on ITC basis

Operating System and Version

• OS: Windows
• Version: SAM 2022.11.21 (Fall 2022 release)
