This only makes the "problem" of the duck curve worse, by widening the part of the day that solar displaces all other generation, and making the switchover point in the evening even steeper. But that's fine, any "problem" potentially caused by the duck curve has long since been addressed by plumeting cost of solar PV and batteries and a host of other improvements put into place since the potential issue was identified. The real problem of the duck curve is that it's become a misunderstood meme that fools people into thinking "we've built too much solar, too fast, which will cause vague problems" when that is far from the case and the number one thing we need to do right now and for the forseeable future to improve the energy grid is build more solar PV.
