Our solar water pumps and solar panels

We use IP6s rated solar panels to power our high-efficiency submersible solar water pumps. This, coupled with a controller that runs at varying time intervals to ensures that water pumping is possible even during low sunlight conditions. 

​

By using a clean, renewable energy source, the Project Maji kiosks have virtually zero energy running costs and are not dependent on the electrical grid. The kiosks are non-polluting and emit no greenhouse gasses as opposed to other motorised pumps (diesel or other fuel).

​

This solar pumping system is controlled using advanced electronics with sensors placed in both the tank and the borehole, which switch off the solar water pump when the tank is full. This prevents overflowing and reduces water inefficiencies. The sensors also cut off the pump supply if the water in the well drops below a preset level, in order to protect it from running dry. The flow sensor records the pumped water volume and updates it on our remote server on a real-time basis, so we can constantly monitor community water consumption and aquifer sustainability.
