The beauty of having a solar powered water fountain is that you don’t need to worry about turning it on and off again.
Thanks to the rechargeable battery, your fountain will continue to run as long as it’s in a well-lit place, and the battery will power the pump throughout the evening - what’s even better is as it’s solar powered, there’s no additional cost to run your fountain!
If you ever did want to turn the fountain off, simply remove or cover the rechargeable solar battery.
