DOE Explains...Batteries. Batteries and similar devices accept, store, and release electricity on demand. Batteries use chemistry, in the form of chemical potential, to store energy, just like many other everyday energy sources. For example, logs and oxygen both store energy in their chemical bonds until burning converts some of that chemical ...

The solar water pump consists of a controller, electric motor or battery, water pump, and solar panels (PV). The solar panel is used to capture energy from the sun. The pump controller regulates the power flow from the panel to the pump. When the pump gets power by the panels, it starts working and pumps water from a well or other water source.
