Solar Panel Compatibility

Are my existing solar panels
compatible with RPS Solar Pumps?

To find out, send our engineers a quick email at [email protected]
with the following info:

1) Stats from the sticker on the back of your solar panels Total Power (watts), Vmp (volts), Voc (volts)
2) The total number of panels you have

Solar Panel Sticker
(on reverse side under junction box)
Stats you’ll need from the sticker.

Total Power ( Pm, Watts )

Voltage Maximum Power ( Vmp, Volts DC )

Voltage Open-Circuit ( Voc, Volts DC )

Optional stats:

Current Maximum Power ( Imp, in Amps )

Short-Circuit Current ( Ioc, in Amps )

Most Common Sizes
“12V Panels”	“24V Panels”
Each panel is different but in general.. Vmp is 16v – 20v Voc is ~20v – 23v Example RPS 100w Panels Vmp = 18.6v Voc = 21.8v	Each panel is different but in general.. Vmp is 30v to 37v Voc is ~38v to 45v Example RPS 290w Panels Vmp = 32.1v Voc = 38.8v

P = I x V (Power = Current x Voltage)
1 horsepower (hp) = 745 watts

RPS Solar Pump System Requirements

Max Solar Array Voltage	72 Vmp 90 Voc	72 Vmp 90 Voc	36 Vmp 45 Voc	360 Vmp410 Voc
Optimal Solar Array Voltage Examples Arrays	24v / 36v / 48v (36-72 Vmp) *Examples*2x 100w 12v panels in series (24v) 1x 300w 24v panel (24v)2x 180w 24v panels in parallel 4x 100w 12v in series/parallel (24v)3x 100w 12v panels in series (36v)4x 100w 12v panels in series (48v)	48v (72 Vmp) *Examples* 4x 100w 12v panels in series (48v)8x 100w 12v in series/parallel (48v) 2x 300w 24v panel in series (48v)	24v (30-36 Vmp) *Examples*2x 100w 12v panels in series (24v) 1x 300w 24v panel (24v)2x 180w 24v panels in parallel (24v)	260-320 Vmp *Examples*16x 100w 12v in series (288 Vmp)10x 290w 24v in series (320 Vmp)
Pump Wattage / Coefficient	Recommend 1.3x or more	Recommend 1.3x or more	Recommend 400 Watts or more	Recommend 1.3x or more
Battery Bank Voltage	Must be same as solar array voltage. (Compatible 24v, 36v, 48v)	Must be same as solar array voltage. (Ideally 48v)	24v Only	Not designed for batteries. Use backup of generator or grid 1 Ph 220v.
