12V Solar Submersible Water Pump — High-Efficiency Filtered Pump for Hydroponics, Fish Tanks, Ponds & Fountains

For best solar performance position the panel at a 40-degree angle from the horizontal plane and orient it to face the sun at 12 noon (similar to the recommended tilt for solar water heaters). The unit includes a dedicated filter to reduce debris entering the internal turbine. This solar water pump kit is built safe and sturdy, contains no harmful substances, and makes an attractive decorative gift for family and friends. Performance notes: a 2.5-meter lift is generally sufficient for most users. If you require a 3-meter lift using a 12V unit with the same power, the solar current must be reduced, which means the pump may fail to start in slightly poor weather. Also note that a 9V6W plus water pump combination can often operate at sunset or under light cloud cover, whereas a 12V6W plus water pump typically cannot.
