Pumping water with the sun's energy
is both cost-effective and reliable for livestock watering,
irrigation and domestic water in remote locations.
a natural alternative to generators, hand pumps and mechanical
windmills for water pumping.
pumps have been in mass production since 1983 and are in use in
of locations around the world. Pumps
that are designed to be powered by solar energy are
far more efficient
than an equivalent AC powered pump.
There are many types of pumps
systems available for pumping
from deep wells, shallow wells, ponds and streams.
Working with USDA, NRCS offices and various
county Soil and Water Districts in NY and PA, we have:

The Grundfos SQFlex Pump System
it’s used for livestock watering, a pressure system at a remote cabin,
or for irrigation, the
SQFlex system can be tailored to any
requirements. Based on the location, depth to water and the
water required, we can find the best pump and most efficient energy
source for your system.
Flex pump can operate at any voltage from 30 - 300 VDC and 90 -
240 VAC without additional controls or different settings. The wide DC
voltage range allows the pump to operate directly from a PV
battery bank. The AC power capabilities mean every SQFlex pump has the
ability to run from
utility power or AC generator for backup

The Grundfos CU200 pump controller
has indicator lights forpump
operation, full water
(with float switch) and a digital readout for input power wattage.
It will shut the pump down for low water level, various service conditions and insufficient power input.
