Solar-powered pumps

A solar-powered pump can provide a reliable water supply and eliminate the installation of power lines in environmentally sensitive areas. Because power lines are not needed, there is not need to spray chemicals around the base of poles.

Solar-powered pumps rely on photovoltaic (PV) panels or modules - composed of silicone cells connected in parallel or series - which generate electricity when sunshine strikes the surface of the cells. Power modules are available in various wattages and voltages. PV panels pose little or no threat to the environment, wildlife and people.

Costs

Because PV systems must be custom designed to user and site characteristics, costs vary. Prices range from $900 to more than $6,000.

Choosing the right system

Factors to consider include:

total and peak power requirements
when the power is needed
reliability and energy storage (battery) requirements

Ask your supplier for more information and advice regarding your specific requirements.
