Sizing the solar panel array to suit the system
If you have not purchased a complete system from your Certified Distributer the
following formula will be sueful. Your certified distributer will be able to help you with
panel selection.
The optimum loaded DC voltage (Vmp) for the solar controller is between 42VDC to
83VDC.
For Hidro-SP067
The maximum open circuit voltage (Voc) is 100VDC. CONNECTION OF SOLAR
PANELS WITH TOTAL OPEN CIRCUIT VOLTAGE GREATER THAN 100VDC WILL
VOID WARRANTY.
For Hidro-SP120, Hidro-SP160
TATAL OPEN CIRCUIT VOLTAGE GREATER THAN 150VDC WILL VOID
WARRANTY.
Solar Panel Requirements
Recommended Power of PV panels (watts)= Rated power of pump (watts)×1.3~1.6
Example:
One SP-067 pump
Power=500 watt pump needs a minimum of 500 watts multiplied by 1.3 to maximum
1.6 to drive the DC motor (500w × 1.3= Minimum Panel wattage required 650w)
Optimum 800 Watt
You may need combinations of series and parallel connections of panels, especially
for the larger pumps. The requied voltage is achieved by connecting the solar panels
in series (series string). The total power requirement (watts) is achieved by
connecting further series strings in parallel.
Panels in series: add the voltage and the wattage of the panels.
Example: 2×36 volt, 8 Amp 200 watt panels in series becomes a 72 volt 8 Amp 400
watt system.
