Background
PPA financial model metrics should be considered as a set: PPA price, IRR, NPV, Size of Debt, and LCOE. For example, in some cases the NPV may be positive indicating an economically feasible project, but some other metric like size of debt, IRR, or PPA price may be unreasonable, indicating the project is not feasible.
SAM does not provide an user feedback when a financial metric is unreasonable, so it is easy to be unaware that there might be a problem with the results.
Task
Add error/warning messages to SSC outputs when PPA metrics are out of predefined ranges, such as NPV < 0, Debt Percent > 100. Get feedback from Finance folks on what those ranges should be -- is there a way to identify an IRR value that might be too high?
