Already have a water feature? The solar powered water pump kit can be used to replace the existing pump of an old water feature, or to convert from mains power to solar power. Easy to use and best of all, no operating costs! Stores power for when the sun is not shining. Most similar water pumps will only function when the sun is directly on the panel, but our high quality solar panel contains rechargeable batteries so that power can be stored, meaning that the pump will continue to work even when there is no sun. Unbeatable quality and value from Primrose. | Primrose Solar Water Pump Kit 1550LPH with Lights & Battery Backup
