Do you have a source for the cooling off effect of the duck curve?
Following is a 2 year old article hinting an increase in the effect https://www.powermag.com/epri-head-duck-curve-now-looks-like-a-canyon/ afaik it hasn't changed much but I'm open to news
I'm not really saying that the curve itself is changing (sorry, I was really not clear), only that those other variables reduce actual energy demand later in the day because of the efficiency gains and thermal banking that happens during the peak energy production. The overproduction during max solar hours is still a problem. Even if the utility doesn't have a way of banking the extra supply, individual customers can do it themselves at a smaller scale, even if just by over-cooling their homes to reduce their demand after sundown.
Overall, the problem of the duck curve isn't as much about maxing out the grid, it's about the utility not having instantaneous power availability when the sun suddenly goes down. For people like me who work from home and have the flexibility to keep my home cool enough to need less cooling in the evening, having solar power means I can take advantage of that free energy and bank it to reduce my demand in the evening.
I get what you were saying now, but having solar would absolutely reduce my demand during peak hours.
It's a neat idea to over-cool in order to reduce consumption later on!
