A Better, Faster Way to Source Pumps

Solar Pumps

What is a solar pump?

A pump that is powered by the sun. They provide an environmentally friendly alternative to electric or internal combustion powered pumps, and they're also great for locations that are far from power sources. Solar pumps are useful in a variety of applications such a drawing water from wells or lakes or they may also be used as circulator pumps for ponds, fountains, and swimming pools. They can also be useful in agricultural and various commercial and industrial applications where gas or electricity-powered pumps can't be used.

How do they work?

Like most devices powered by the sun, solar pumps use photovoltaic power cells to convert solar energy into electricity. This power is stored and put to use when the solar pump switches on. The pumps themselves may be positive displacement pumps such as diaphragm pumps or piston pumps, or they may be centrifugal pumps.

Both categories have advantages and disadvantages. Positive displacement pumps can be used to create a greater amount of pressure, which is useful when the liquid needs to be pumped longer distances. Centrifugal pumps can usually handle greater volumes of liquid.

Here are a few solar pump manufacturers to consider.
