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.

Transforming rural water consumption

Adverse impacts of climate change put big pressures on waterscapes and triggers water scarcity, severe droughts and unpredictability of rainfall as a result of changing weather patterns. We adhere to sustainable groundwater practices, avoiding the risk of over-abstraction to ensure future generations will have access to groundwater. As part of our site selection strategy, we prefer existing aquifers as opposed to drilling new ones. We aim to mechanize borewells with broken handpumps to reach communities currently deprived of a clean water source. A pre-installation pumping test helps us to ensure the extraction does not exceed the replenishment rates.
