How the Process Works

• Heat transfer is based on the patented technology
• Designs are modified to satisfy needs
• Solar cells overlay a confined body of water in an evaporating tank
• Water vapor is condensed in copper pipes under the cells
• Heat consumed to evaporate the water is released back to the body of water when condensation occurs in the copper pipes, where it warms up the raw water
• Warmed water will rise up towards the solar cells on top of the tank where it is heated through solar rays, and the resulting vapor is guided back to condensing pipes
• The outcome is distilled water and some reject water.

Conventional desalination systems are expensive to build and consume a great deal of energy, which makes them expensive to run. Capturing, storing and efficiently harnessing solar energy has been the dream of generations of researchers. At SWE, we have developed the technology to optimize the natural resources of solar energy, ocean water and brackish water to produce life sustaining potable water and electricity at nominal cost, making researchers’ dreams a reality.

On-shore solar distillation systems are contained in steel or concrete tanks over the ground and process ground or brine water. Solar energy increases the temperature within the water production structure, with minimum use of fossil fuels. The desalination process continues 24/7. The smallest plant will produce 230 m3/day. The average return on investment is 35% PA.

Off-shore solar distillation systems use floating solar cells over a body of water and basic thermodynamic principles to convert ocean water into fresh water and renewable energy. Solar cells are installed as close as 100 feet to the coastal line; the depth of the structure is within 60 feet. Like On-shore plants, the desalination process continues around the clock. A plant could cover half an acre and produce from 43,000 m3/day to 700,000 m3/day. ROI: 20% PA.
