A video describing a 2 part solar water pumping system.
PV direct water pumping from a well to fill a 2500 gallon cistern.
Then a 48 volts Dankoff SolarForce Piston pump to boost the water pressure up to 65 psi and 9 gallons per minute.
System is installed in parallel with a Franklin submersible and a Simple Pump hand pump.
