Ok everyone, so im a new to engineering and we have to complete a prototype design and I want to build a aquaponics fish farm that is run by solar panels. I have three 7v solar panels that peak at 1.2 watts. I want to wire them in parallel or series whichever will do the trick so a assortment of 9v rechargable battery's with a controller to stop them from overcharging. I need them to to hold enough power to run my water pump at a constant 9 volts for at least 6 hours. How many batteries do I need and are these solar panels sufficient to charge them? If not what would I need? And does anyone have any resources I can look up on how to construct such a battery system? Thanks for any advice and help!
