Lack of access to affordable energy and post harvest spoilage are long-standing problems facing Africa's rural farmers. Dairy farmers without access to electricity and refrigeration can lose up to half of the milk they produce due to spoilage. Most rural farmers must often travel long distances to deliver their milk to Milk Collection Centres (MCCs). As dairy cattle are milked daily in the mornings and evenings, it is typically impossible for dairy farmers to deliver and sell their morning milk without a solution to preserve the evening milk until it can be delivered to collection centres, leading to significant losses.

WE Company in partnership with the University of Hohenheim implement WE Coolers – an innovative farm-based solar milk cooling system that helps Africa's dairy farmers to increase their productivity up to 25%. The system utilizes powerful photovoltaic panels to power a Smart Ice production system specifically tailored to preserving evening milk. Complete with milk canisters customized for the system, the system allows rural farmers to increase their revenues through preventing spoilage and also provides lighting and phone charging capabilities contributing to rural electrification. With farmers increasing their production capacity, Milk Collection Centres (MCCs) also benefit through increased quality and quantity of milk, reduced energy use hence reduction in carbon emissions from diesel generators, thereby benefiting the entire rural value chain.
