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 Please note fountains should always be emptied and covered or emptied and brought indoors before freezing weather occurs. Place the solar panel in a clear sunny area for the best performance of your solar fountain. 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.
