Patented technology

Inspired by nature, Desolenator replicates the water cycle by harnessing solar energy in a new way. After years of R&D, our team of engineers, alongside some of the world's leading water experts, have designed the next chapter in water innovation.  

4x solar efficiency
Patented photovoltaic-thermal technology for optimised solar energy conversion.
24/7 operation
Integrated energy source for lifetime operation. No downtime. Grid independent. Minimal batteries.
250 m3/day modular
Scalable systems for remote deployment, at a low levelised cost of water.
95% reduction in chemical use
No filters. No membranes. No harmful chemicals.
Electrical energy
PVT array powers the plant (control system, pumps, sensors etc)
Thermal energy
PVT array heats up cold water before it is fed into a flash-tank to produce steam to drive the MED process
The MED process
Distils the seawater (or other local water source) into clean water

The old way.

Sustainability (as a cost). Centralised, industrial plants. Lifelong operating and energy costs. Toxic chemicals. Plastic bottles and water trucks. Complex supply chains. Carbon emissions.

The Desolenator way.

Disrupts the water supply chain. Integrated solar energy. Low OPEX. No consumables (no filters, no membranes). No harmful chemicals. Ocean safe. Regenerative water supply.

The novelty of our approach is that we use both solar-generated heat and electricity to power the desalination process. 24/7 water provisioning from the sun.

Energy harvesting

Our patented PV-T panels capture both electrical energy (which is optimised due to panel cooling) and thermal energy, raising our solar energy conversion from an average of ~15% to ~60%.


There is a built-in process to remineralise the clean water produced to make it suitable for drinking, or for a business-specific application.

Water purification

A Multi-Effect Distillation (MED-MVC) vessel distils complex water types into high-quality product water. Desolenator’s patented design enables flexibility in deployment and ease of adding capacity.

Energy storage

Excess electricity from the solar array is stored in batteries. Excess thermal energy is stored in hot water tanks fitted with a thermal battery, to provide an uninterrupted 24/7 energy supply.

The solution that Desolenator has originated is not only an elegant solution that holds the promise of being low in capital and operating costs but also is deployable as standalone units to remote locations.
