First, the hydropanel takes in ambient air via fans and collects water vapor from that air onto a hygroscopic material (that can absorb moisture). With heat from the sun, the hydropanel.
Researchers at MIT and elsewhere have significantly boosted the output from a system that can extract drinkable water directly from the air even in dry regions, using heat from the sun or another source.
“Conventional desalination technologies require steady power and need battery storage to smooth out a variable power source like solar. By continually varying power consumption in sync with the sun, our technology directly and efficiently uses solar power to make water,” says Amos Winter, the Germeshausen Professor of Mechanical Engineering .
The new machinery could offer remote and dry regions both electricity and some water for drinking or crops. This artist’s drawing shows what a new water- and energy-production system might look like. Its solar panels generate power as a water harvesting unit pulls moisture from the air.

6 FAQs about [Can solar panels generate electricity to make water ]
How do solar panels collect water?
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. This is a bottle holding some of the water collected by the new solar-and-water system being developed by researchers in Saudi Arabia. R. Li/KAUST
Can solar panels harvest water without using electricity?
A three-month trial in Saudi Arabia has shown that a solar panel add-on system can harvest water without using any electricity by exploiting the day-night warming and cooling of solar panels. In fact, the system slightly increases the electricity-generating efficiency of the panels by keeping them cooler.
How does a solar panel work?
1. The sun powers fans that pull air into a hygroscopic material which captures water vapor. 2. Solar power causes the materials to release the captured vapor in a concentrated air stream. 3. A smart controller ensures that the dew point inside the panel is above the ambient temperature causing passive condensation of pure water.
How does a solar hot water system work?
Photo: A different and much bigger solar hot-water system. This one uses parabolic mirrors to collect the Sun's energy and focus it onto water pipes running through their centers. The water is pumped back to the building in the background (Jefferson County Jail in Golden, Colorado).
How much water can a solar panel produce a day?
The humidity in the closed box gets so high that the water condenses on the metal and can be drained from the box. During the trial, from May to June 2021, a small prototype system produced 0.6 litres of water per square metre of solar panel per day.
How much water does a solar-powered desalination system produce?
The system delivered pure water that exceeded city drinking water standards, at a rate of 5.78 liters per square meter (about 1.52 gallons per 11 square feet) of solar collecting area. This is more than two times as much as the record amount previously produced by any such passive solar-powered desalination system, Wang says.
