My argument is that as Solar policies shift due to increased adoption, as NEM goes away the 'cost' of clipping will be significantly reduced. In SPS territory in TX there is no NEM. A kWh exported is worth ~80% less than a kWh self-consumed. Even with storage increasing generation when it's needed is cheaper than storing mid-day surplus. So energy added in the morning and evening will likely be worth ~5x more than energy that would be lost mid-day. Sure, if it's just a $150 step change to the next size inverter it may pencil out but this is often not the case. The system profile I attached would have required a $5k service upgrade to increase the inverter capacity.
And 'inverter stressing' isn't a thing. SMA actually published a white paper explaining that failure rates don't increase even with arrays oversized by 200%.
