DC to AC Ratio Not Properly Displayed

I designed a DC to AC Ratio of 1.24 and then go to the time value graph series to show the clipping and degradation of DC over a 25 year period, along with the AC kW generation overplayed, and staying constant over that time. But this is not properly reflected on the summary screen for annual energy production of kWhs. The kWh are degraded over time. Please advise.

Thank you for your response. Got it DC-STC and AC Rating of inverter is how SAM works. Your example did not make sense to me. In the end we all want to define the economics of a system. Among other reasons for stacking a high DC to AC ratio, the primary one is energy value over time. I need to substantiate that I can conservatively deliver the same kWhs of production from year 1 to year 25. Many inverters have a limited DC to AC stacking ability. This is one reason I use HiQ inverters as they can take a ratio up to 6.35. Not that anyone would do it, but I know I am safe with higher ratios that may be needed... by economic design, and depending on location temperatures. I usually factor modules degradation with PTC values and inverter AC-CEC ratings to be conservative. I like that SAM graphs the DC degradation mapped over the AC kW output... and demonstrates no AC kW degradation over the 25 year period. The net effect is no degradation of kWh over the 25 year period. I understand I can cheat SAM with inputting zero DC degradation of the modules, but this not a correct approach in my mind. Seems the summary would reflect the net affect of the design and show zero reduction of kWhs over the project life. The summary graph mis-represents a project using a high DC-AC Ratio.
