Hi,
To the best of my knowledge, I'm entering data into SAM in the same way that I'm entering data into the SSC library. The results are the same until I enter an ITC value. SAM shows a federal ITC on the Cash Flows page, but SSC returns itc_fed_total as 0. Am I missing something that I should have set up for itc_fed_total to have a value?
I'm running pvwattsv1, annualoutput, and ippppa, specifying a PPA price. When the ITC amount and percentage are set to 0, all of my resulting cash flows from SSC match SAM's. When I add either an amount or percentage for federal ITC, SAM seems to notice, but my SSC results are unaffected.
Any idea what I might be missing? I've attached the SSC script for reference.
