12V Solar Submersible Water Pump — Aquarium / Fish Tank / Hydroponics Filter & Aeration Pump for Pond, Rockery & Outdoor Fountains, High Efficiency

For best performance place the solar panel at a 40 degrees angle relative to the horizontal; aim it to face the sun around 12 noon, following the same installation angle used for solar water heaters to maximize energy capture. The unit includes a specially designed filter that effectively reduces foreign matter entering the internal turbine, protecting the mechanism and prolonging service life. This solar-powered pump kit is built to be safe and robust—free from any harmful substances—and makes an attractive decorative addition or practical gift for family and friends. Typical installations find a 2.5-meter lift sufficient. Note that if you require a 3-meter lift using a 12V pump with the same power rating, the solar current will need to be reduced; under slightly poor weather this can prevent the pump from starting. In low-light conditions, a 9V6W setup with the water pump can still run at sunset or with light cloud cover, whereas a 12V6W configuration generally will not.
