Information
●Solar Water Pumping System Working Instruction
To be able to make proper selections on PV module and battery for solar water pumping system, we need to know how this system running. Thru the operating process, solar panels convert sunlight to electrical energy which is passed to the solar pump controller.
The solar controller stabilizes the voltage and output power to drive the pump motor. If backup batteries (optional) are installed in the system, then the pump controller can also charge them. The stored power can be used during the evening or when the sunlight is not adequate to drive the pump.
Sensors are also connected to the controller and can be used to protect the pump from running dry as well as to automatically stop the pump working when the tank is full. 

●Selecting Proper Pv Module For Your Solar Water Pumping System
Power of pump (watts) x 1.3 ~ 1.6 = power of PV panels (watts)
Eg. A 300 watt pump needs a minimum of 390 watts of PV panels to drive it. (300w x 1.3 = 390w)
Panels in parallel, add the AH, voltage stays the same.
Panels in series, add the voltage, AH stays the same.
Eg. 2 x 12 volt 100 watt panels in parallel becomes a 12 volt 200 watt system
2 x 12 volt 100 watt panels in series becomes a 24 volt 200 watt system
 
●Selecting Proper Controller For Your Solar Water Pumping System
The controller should be matched with the pump especially compatible with pump voltage and PV module as well. For different size of pumps, we pair different controllers running under recommended PV module connections.
