Portable Solar Pumps

Technology

With the affordable portable solar pump, farmers can still grow crops during the 6-month dry season and thus ensure that everyone in their area has food.

The pieces of land where farmers in Zambia grow their vegetables are often quite a distance from the homes, close to a river or stream or a place where the groundwater is not deep. To accommodate these farmers, Jacana has developed a portable solar pump. The system consists of two solar panels and a pump that can be put in a river, open well or stream. It comes with a hose pipe and the total weight is approximately 15kg. This makes it possible for farmers to take the pump to the field in the morning and store it safely in the house in the evening.

In addition, the pump including panels and pipe currently costs less than USD 185 (at this moment (2024), that includes transport and profit for the distributor and local shops). An average farmer can pay for this with the proceeds of one harvest. See: www.portablesolarpumps.com
