Sunnydaze Solar Pump and Solar Panel Kit With Battery Pack and LED Light, 78 Inch Lift Overall 10 watt solar panel measures 14 x 12 x 1 inches. Panel comes with ground spike and wall mount hardware. Water flow is 211 GPH with maximum lift of 78" when a 1/2" tube is connected and conditions are optimal. The pump comes with adapters so you can make your own pond fountain or convert an electric pump to a solar pump. The pump and adapters fit the inside diameter of a hose that is 1/2". The included LED light turns on/off at night automatically so you don't have to remember to turn it on or off. The solar on demand technology allows your fountain to run in and out of the sun. The sun is needed to charge the solar panel but then the "on demand" can keep the pump running when the clouds come out. If it is dark or cloudy, the battery can run the pump; just push the battery on/off button to run on battery power. If fully charged, the batteries will power the pump for up to 4 hours. When the batteries are depleted, you can press the battery on/off button to switch to sun power. Sunnydaze Decor backs its products with a 1-year manufacturer's warranty.
