Do Solar Water Pumps Require Batteries 

I have a low production well that is supposed to produce one gallon per minute. I really like the idea of using your solar powered well pump and the controller that allows me to Adjust the amount of water I am pumping. But I plan on having my own Solar panel array with batteries and generator backup and inverter so do you have a similar system with control box, pump, well water sensor, and storage tank sensor that I can power with 110 Volts?

Can you pump AND charge batteries at the same time ? So you could extend irrigation time to say 10 hours ? For drip irrigation ???

I would like to build a solar 10Kva power back up with batteries using 2submersible 1.5 HP pump 2litre per second. How many panels and batteries would I need?
