Solar panels  is to  convert sunlight into electrical energy which will be passed to the solar pump controller,the energy will be used to power the pump. 
Solar Controller /Inverter is used to stabilize the power voltage and output the power to drive the electric motor of the pump. If backup batteries (optional) are available, then the pump controller can charge them.
Battery is for Storaging the additional  energy that can be used at later time when the sunlight may not be adequate to drive the pump.
Water Level detector / Sensors is used to connected to the controller and can be used to protect the pump from running dry as well as to automatically turn the pump off when a water tank is full.
