Solar Pump
$350.00
Solar photovoltaic panels convert sunlight to electrical energy which is passed to the solar pump controller. The solar controller stabilizes the voltage and creates a three-phase output to drive the electric motor of the pump. Sensor is also connected to the solar panels which automatically turns the pump off when a tank is full of water. The system can be remote from traditional power sources and fully automatic with no on-going electricity charges.
Selecting the solar panel of the pumping system
Please note: The Open Circuit Voltage of solar panels is about 45V and the Maximum Power Voltage of solar panel is about 36V which are suitable for solar pump of 24V and 48V.

Product Description
Selecting the solar panel of the pumping system
If you have not purchased a complete system from your supplier, the following formulae will be useful. Your pump supplier will be able to help you with panel selection.
A. Solar PV panel (solar panel) selection: Voltage of solar panels = Rated voltage of pump (volt) x 1.5. Power of solar panels =Rated power of pump (watts) x 1.5. eg.:3SES1.5/80-D24/210 The voltage of solar panels: 24V x 1.5=36V The power of solar panels: 210w x 1.5=305w The controller will already be matched to the pump by your supplier.
b. You may need combinations of panels, especially for the larger pumps. During connection of solar panels, you have to get the solar panels in series in a line to reach the rated voltage of the pump. Then get the lines mentioned in parallel to reach the rated current of the pump Panels in parallel, add the current and the wattage of the panels Panels in series, add the voltage and the wattage of the panels. 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.
c. You can select and connect solar panels as the following pictures showed:
