CWT has designed and installed grid-tied solar systems to offset the energy demand of Seawater Reverse Osmosis (SWRO) desalination plants.  With funding from the Caricom Community Climate Change Center, a 75.9 kWp grid-tied solar systems were installed in Bequia, St. Vincent & the Grenadines in 2012 to off-set the energy demand from a 35,000 gpd SWRO plant, a 114 kWp system in Carriacou in 2014 to off-set the energy demand from a 35,000 gpd SWRO plant, and 150 kWp system in Grenada in 2016 to off-set the energy demand from an 80,000 gpd SWRO plant.


CWT has developed a low cost, solar brackish RO desalination system for residential, small community and agricultural applications.  Grant funding was received from the Caribbean Climate Change Innovation Center, an initiative of the World Bank to successfully develop and demonstrate the technology over the last 18 months.  Contact us for further information.
