Much also depends on the tilt angle of the panels (need steeper in winter, flatter in summer), and the direction they are facing. My little "shed" system has 1,260 watts of panels wired 3S2P, facing due south at a 26.5 degree tilt. They're connected to a Victron MPPT charge controller. On sunny days in the summer I can produce 1,000 watts + for about 2-3 hours of the day, and for a portion of that, I'm almost at the full 1.26 kw. But it's not anywhere near that early in the morning, or late in the day. And on a winter day, I'm ready to jump for joy at anything over 800 watts, and that happens for maybe an hour. So, I think we need to know a bit more about the situation. In some situations, that may be all you're going to get, in winter.
