Abstract: A water feature comprising a vessel (1) for containing water, an electrically powered submersible water pump (2) within the vessel (1) for pumping water to an outlet of the water feature and a solar panel (4) arranged to provide electrical power to the water pump (2). The solar panel (4) is arranged within said water vessel (1) above the water pump and so as to be beneath the water level (7) in the vessel (1) in use.

Abstract: The invention relates to an apparatus for controlling an energy flow between a solar energy source and an electric motor. An electrical circuit having an energy flow control device is arranged between the input side and the output side. In accordance with one aspect of the invention, the circuit has an energy store, which is connected to the energy flow control device. This energy flow control device is designed to pass energy stored in the energy store to the motor in the event of a predetermined first voltage threshold of the energy store being exceeded. The invention also relates to a solar energy source having a corresponding apparatus and to a method for controlling an energy flow.
