Maybe not peak, but there is significant overlap, and batteries are cheap enough to cover the gap for the non-overlapping part (e.g. 7-9pm) Whereas for winter

Maybe not peak, but there is significant overlap, and batteries are cheap enough to cover the gap for the non-overlapping part (e.g. 7-9pm) Whereas for winter heating, you would want to preheat a lot, and you would also need an oversized PV array, because there's just way less energy available from the sun.
