@VikingWays @sickburnbro In general, you should get the biggest array you have space for, because the array is going to be way cheaper than lithium batteries.
Store the energy as heat in your house (heatpump / AC) or water tank (they make resistive heaters especially for this)

Take a minute to calculate your costs if it's gonna be a plant this big, I thought you only wanted to run your pump

If you're worried about ice storms, probably not your best bet. If you install it right, it won't break but you're not gonna get much power out solar in 10 ft visibility, cloudy day, frozen panels. You're gonna have to wipe the frost off at least.
