Solar Cold Storage · TEN Model

Keeping the harvest fresh, long after it leaves the farm.

WaterBrooks Technologies builds solar-powered, IoT-monitored cold storage that helps African farmers preserve their produce for longer, waste less, and earn more without relying on diesel or the grid. Beyond storage, we also provide farm-to-market transporation, ensuring produce can be moved efficiently from farms to markets while maintaining its quality and freshness throughout the journey

The problem

Africa is losing food it already grew.

According to the FAO and WHO, Nigeria loses up to $10 billion a year to post-harvest losses with nearly half of all perishable produce spoiling before it ever reaches a consumer. Poor storage, weak infrastructure and rising temperatures leave smallholder farmers selling in a hurry, at a loss, or not selling at all.

Diesel-powered cold storage exists, but it's expensive, polluting, and out of reach for most smallholders. The gap needs a solution that's clean, affordable, and built for where farmers actually are.

Our approach

Technology, Education, Nutrition (TEN) model

Hardware alone doesn't change behaviour. We pair solar cold storage with training and nutrition awareness so the tools actually get used, and used well.

Technology

Solar-powered, off-grid cold storage units with IoT and AI monitoring extending shelf life from an average of 5 days to up to 21, and cutting spoilage by 60–65%.

Education

Hands-on training, workshops and outreach that equip farmers with the knowledge to adopt effective preservation practices and not just the equipment.

Nutrition

Awareness programs on nutrition and sustainable agriculture that help communities understand and act on the real cost of food waste.

Solar panels powering rural infrastructure

Our solution

Off-grid cold storage that thinks for itself

Our units run entirely on solar power, so they work in rural communities with no reliable grid. IoT sensors track temperature and humidity in real time, and AI turns those readings into predictive insight telling farmers and cooperatives when to store, move, or sell produce for the best outcome.

The result: shelf life extended from 5 days to up to 21, spoilage cut by 60–65%, and a training program that makes sure the technology is adopted, not just installed.
