Solar-Powered Milk Chillers are refrigeration systems designed to operate in off-grid or energy-poor regions, using solar photovoltaic panels and thermal storage to cool milk immediately after milking. These systems are critical in rural dairy production, where a lack of cold storage leads to high post-harvest losses and reduced market value.
By maintaining milk at required temperatures (below 4°C), these chillers extend shelf life, ensure food safety, and allow smallholder farmers to participate informal value chains. They are often modular, easy to transport, and require minimal maintenance.
The technology supports livelihoods, enhances nutrition security, and reduces the need for diesel-based cooling, aligning with clean energy and sustainable agriculture goals.
