Solar pump

[verbotenwhisky]

I do not have a battery system for the hot water heater. We have enough sunlight most days that the tank will last for the night. We can run the electric when it is needed for cloudy days

One of the things that having a battery does for you is insures your end user, the motor, has clean consistent voltage through it's cycling. Every Solar project I have messed with, all 3 to be precise, have charged batteries and the end users have run off the batteries which is to ensure consistent power and in the case where you have variable loading to ensure peak surge power where required. I am not saying this is the way to do it every time nor am I saying the way you are doing it is wrong, just throwing it out there for the thought process.
