Solar Only Feature: Standard solar fountains do not store solar power; they operate only when the panel is placed in direct sunlight. The panel is connected to the pump via a cord but they do not have a battery pack. Without direct sunlight the fountain will no longer run until after the sun comes out again. Place the solar panel in a clear sunny area for the best performance of your solar fountain. This wall fountain can be hung from a wall or set on the floor of your deck patio or on a level ground against a wall. Color can vary slightly on each fountain. Lighting can be different indoors and out as well as differences in computer monitors. So slight color variation is not a cause for return. Please view the Media Tab for a video of this fountain.
