Solar Water Pump

The solar pump system consists of solar panel on a mounting structure, a pump controller, an electric pump and a storage tank for water. The big advantage of the solar energy driven pump is that there is no battery necessary to back-up the solar power. The solar pump is connected to solar panel, so water is pumped from low to high level in case the sun shines. The water is buffered in the tank that is mounted at a higher level than the taps. In this way there is pressure on the taps and there is water available if the sun is not shining. The function of the water tank is comparable to the function of the battery.

To obtain a good match between solar panels and the pump, the pump controller is connected in between. This controller makes the solar energy driven pump a unique product. Not any other pump can be used, on the contrary! The controller converts the direct current from the solar panels into alternating current with a frequency that depends to the irradiation. At the low irradiation, for example in the morning at sunrise, the pump will be driven by a slowly rotating engine. The speed of rotation will increase when the sun rises in the course of the day.
