The daytime sun that powers the solar panels also warms the hydrogel-based material. That heat drives the stored water out of the material and into the collection chamber.

Today, photovoltaic solar cells account for about 1.5 percent of the nation's electrical supply. That represents a saving of99 billion gallons of water a year, the authors estimate, which is equivalent to about four days of California's total water usage. But as the solar percentage grows, so too will the savings.
Mapping of the global potential of atmospheric water harvesting using solar energy shows that it could provide safely managed drinking water for a billion people worldwide based on climate suitability.
Or, the water can quench the thirst of people or crops. Wang and his colleagues tested the system under the hot Saudi sun in a three-month trial last summer. Each day, the device collected an average of 0.6 liter (2.5 cups) of water per square meter of solar panel. Each solar panel was about 2 square meters (21.5 square feet) in size.
Electricity-generating rooftop solar cells not only save on planet-warming carbon emissions,they also save a significant amount of water. Water consumption is tightly bound to energy use, because without water we cannot mine, drill, frack, or cool thermoelectric and nuclear plants.
Researchers from Shanghai Jiao Tong University in China developed a promising new solar-powered atmospheric water harvesting technology that could help provide enough drinking water for people to survive in those difficult, dryland areas. They published their work in Applied Physics Reviews, an AIP Publishing journal.
