How does a solar-powered fountain work?


Quick Answer

A solar-powered fountain works with a small solar photovoltaic panel that converts the sun’s radiation photons into a DC electrical current, and operates the pump of the fountain’s closed loop water stream. The most basic type of solar-powered fountain connects directly to a solar panel, and only operates with direct sun exposure. Other types of solar-powered fountains have battery banks that store energy in order to continue operation at night and in cloudy weather.

An external energy source, such as a solar panel or battery, pumps the water from a fountain’s reservoir to the higher level from which it again falls. Gravity then pulls the water back into the fountain's reservoir. With a solar panel, the sun’s radiation is the external energy source that operates the pump. All energy a solar-powered fountain uses is free of cost and environmentally friendly. A solar fountain requires little maintenance.

There are many advantages to a fountain powered by a solar panel, such as its high mobility. The location of a solar fountain does not depend on external electrical connections, and installation is simple due to the lack of power cords and electrical lines. To operate a standard fountain pump with solar energy, it is possible to install a solar panel directly to the existing pump or battery.
