Using PVs to Pump Deep Wells
Richard Perez
What can we do when the water lies deep down the well and all we
have for power is sunshine? Well, thanks to the folks at SolarJack+
and Kyocera, we can get along quite nicely. Read ahead and see how
this family pumps their water from 400 feet down using sunshine.
The Situation
Don & Carly White live on a mountainside near Jacksonville, Oregon.
Their homestead requires a water system that could pump water from
a deep well and do it without commercial power. The Whites estimated
that they needed about 1,000 gallons of water daily to support their
homestead and garden. They sought the aid of Electron Connection
Ltd. in solving their water pumping problems. Here are the facts
of Don & Carly's water situation.
The Well
The well was already in place so this factor was given (wells being
difficult to move). It was drilled, with a 6 inch steel casing,
512 feet deep. The static water level in the well is 120 feet down
from the top of the casing. According to the records of the well
drillers, the main flow of the well is 9 gallons per minute (GPM)
and is located at approximately 480 feet down from the top of the
well casing.
The Site
The site surrounding the well has excellent solar insolation. Wind
is minimal at this location and no microHydro potential is present.
The water from the well has to be pumped an additional 75 vertical
feet from the well head to the 3,600 gallon water storage tanks.
Possible Solutions
We considered all the options. Wind powered jack pump, submersible
deep well pump powered by either 120 or 240 vac from either a generator
or inverter, and a PV powered solar jack pump were considered. The
Whites selected the PV powered SolarJack+ pump because it is quiet,
reliable, and does not require the use of generators, inverters,
batteries, or commercial power.
