No, peak generation in most countries is in the late afternoon when people come home from work, the ac kicks on, people start to cook + do other things around the house. You typically see a double- peak, one in the morning and one in the evening, although it varies based on the seasons. I'm an engineer who works in renewable energy and the stated problem is real- solar generation doesn't line up very well with grid demand. You can work around this with energy storage but that is an expensive solution
