This solar with battery backup pump and panel kit is perfect for creating a solar garden fountain, converting an existing one to solar, adding movement to a birdbath to keep the mosquitoes away, or for bringing life to a pond. This kit comes with everything needed to do any of the above projects. With the solar panel charging the battery pack, there is no need to worry about any extra additions to the electricity bill. Please note that the battery generally lasts between 12-18 months, but with repeated charges and discharge cycles the battery will become less efficient and battery capacity may reduce.
