Amerigy's Solar Roller solar electric generator, provides a flexible platform for delivering
electricity to
water pumps without long and expensive electrical cable runs.
There are two basic approaches: direct-coupled and battery-coupled solar pumping systems.
Direct-Coupled - Provides the simplest solution. Electricity generated by Solar Roller
is sent directly to the DC pump,
which pumps water from a stream or other water source to one or more water storage tanks. Because of the volume variability
of water pumped during different sun conditions,
water storage tanks are generally sized larger to provide a buffer for periods of low production.
Battery-Coupled - Amerigy offers a Solar Roller model with integrated battery packs. This allows energy generated during
sunny periods to be stored for later use so water pumping can occur when there is no sun.
Which is better? There is an investment trade-off between tank size or batteries. Some information sources are listed
below to help you make the best decision for your situation.
"Many people considering a solar water pumping system are put off by the initial expense. Looking at the big picture,
though, gives a better idea of the actual cost. For one thing, utility line extensions commonly cost $10,000 to $30,000
or more per mile. One rule of thumb is that remote pumping (whether solar-, wind-, or generator-powered)
is worth considering whenever the distance from the utility grid exceeds about one-half mile."
