Scientists have recently developed a system that harvests rainwater running off photovoltaics (PV) panels for household use or hydrogen production. Their analysis showed that, in the southern Sahel, the system can meet both the energy and water requirements for electrolysis, with surplus rainwater covering up to 50 percent of a household’s daily water demand.
A European team of researchers has proposed a system that harvests rainwater running off PV panels for household use or hydrogen production.
“The combined water and energy harvesting by PV mini-grids may have the potential to increase water security by making more water available for domestic use or crop irrigation in the dry season,” said the researchers. “There are very few small studies looking at water harvesting from panels, quantifying the capture, but scientific data is extremely scarce,” corresponding author Dr. Maarten Waterloo said to pv magazine.
