Water Shortages Addressed by the Installation of a New Solar Desalination System

Water Shortages Addressed by the Installation of a New Solar Desalination System

In Mombasa, Kenya, and La Gonave, Haiti, this year’s quarter, GivePower is introducing containerized, solar-driven water treatment and purification network. Like the first solar-powered desalination plant by GivePower in Kiunga, Kenya, to work with the Tesla energy wall-battery storage system in 2018, several new projects will be pursued.

The two new non-profit solar water farm schemes are to produce up to 75,000 liters of water per day, by combining a 50 kW solar system with 120 kW / h of Tesla batteries. Which together, drive two low-wattage desalination osmosis pumps,  running simultaneously to maintain continuous operation.

Once solar-powered desalination systems get installed, it is essential to pin down the economic benefit of the technology and the operational model. The energy required to desalinate seawater is one of the significant challenges of solar desalination. Sometimes, this excessive energy requirement implies that a plant needs a more extensive solar array, which raises the project cost.

“We must see that[ the philanthropic] programs are economically sustainable–they will operate without constant donor funding to keep the structures working,” says Kyle Stephan, vice president of operations at GivePower.

The Solar Water Farm Units of GivePower cost just about $500,000 and seems to last for 20 years.

As said by Hayes Barnard, CEO of GivePower, commercial applications for solar water farm technologies from GivePower are not in the pipeline as of now.

While establishing commercially off-grid, solar-powered desalination facilities for coastal communities, the industry management sees microgrid participants as especially well-advised to provide solutions to solar.

The need for ways to combat water scarcity using renewable energy is stepped up by drought, saltwater pollution, and weather change. At the same time, declining PV prices and innovations in energy storage make solar-powered desalination systems more appealing.

To date, all solar water plants at GivePower are well-established coastal desalination plants. Barnard stated that 98% of the planet’s water is within the ocean, and 73% of the globe’s population lives on the coastline, where water in wells could become brackish. Also, the processing cycle of off-coastal solar desalination plants is expensive, and well-based coastal solar water farms can not pressure underground aquifers.

GivePower follows the International Building Code structural specifications for its solar water plant’s concrete foundation for its La Gonave project, which is off-coast of Port-au-Prince and constructs a solar canopy that can survive a hurricane of category four. 

At first, the non-profit centered towards supplying solar-powered electricity in the hope of opening up education chances for girls in under-developed countries to schools without electrical power. But it quickly became apparent that it was essential to help the communities attain water safety, as girls often skipped school, as they spent their days fetching water, according to GivePower’s Co-Founder Barnard. In 2016 GivePower became an independent corporation.

Last week the UAE’s Global Water Impact Award for small creative projects was awarded to GivePower’s solar-powered desalination technology.
