CSIR validation: 98% cleaning efficiency for our solar winnower

Our solar-powered grain cleaner and winnower has completed independent testing by the CSIR-Crops Research Institute under Ghana's Ministry of Food and Agriculture.

The results confirm what farmers in the field have been telling us: 98% cleaning efficiency, 363 kilograms per hour of capacity, and 9.8 hours of battery runtime on a single charge — enough for a full working day off-grid.

Crucially, the machine avoids roughly 2.18 tonnes of CO₂ emissions a year compared with fuel-dependent cleaning, and it removes one of the most physically demanding tasks from the post-harvest chain, work that falls disproportionately on women.
