Sustainable PV-thermal desalination for water scarce coastal regions
Desalination
Water scarcity threatens agriculture, coastal infrastructure and livelihoods as droughts become more frequent and severe. Our solution provides sustainable freshwater from seawater using simple, scalable technology.

Product description
Hand on Water is redefining how freshwater infrastructure can be built in a changing climate. Instead of relying on increasingly vulnerable centralised systems, we develop modular, solar powered desalination units that can be deployed wherever seawater, sunlight and basic infrastructure are available. Powered by second life photovoltaic modules and built from locally available industrial components, the systems establish a scalable blueprint for resilient freshwater production. They strengthen long term water security using resources that already exist in abundance: sunlight, seawater and existing solar panels. As freshwater becomes one of the world's most critical strategic resources, Hand on Water demonstrates a practical pathway towards decentralised, sustainable and scalable water infrastructure.
Key characteristics and environmental benefits
The system is modular and fully scalable. Each unit operates independently and can easily be expanded as demand grows. It is powered by second life photovoltaic modules and operates entirely on renewable energy. No grid connection or chemical treatment is required during normal operation. The system provides a reliable source of freshwater independent of rainfall. This strengthens long term water security for communities, agriculture and critical infrastructure. It enables the greening of arid regions, protects agricultural yields and helps secure livelihoods in remote and drought affected areas. Minimal infrastructure requirements allow seamless integration into ports, farms and urban environments. Seawater, sunlight and second life PV modules are already available in abundance, creating enormous potential for sustainable freshwater production.
