Ingenious Water Purification While producing Electricity From Solar Panels

By: Eugene Wilkie
In the early days of my career in the renewable industry we were constantly in a position of having to engineer, innovate and constructing in the field. I have watched many of these fly by the seat of our pants innovation become main stream in the industry in the last few years. I am impressed at some of the technology that is coming out of academic research and development but some times the greatest innovations come from folks out in the trenches. For years my career was located in out of the way locations in emerging or third world countries where we had little or no access to store bought components if they even existed. We built solar ovens from card board boxes and tin foil. Racking for the solar panels were always built from material available. I actually constructed solar racking one time from drift wood harvested from the beach in the Caribbean. I kept getting sick from water sources so I built a water evaporation unit to have a source of purified water using the windshield of a abandoned car.

When I see innovations like the one below I get a bit nostalgic as I truly believe the mother of all inventions is founded on the bases of necessity. When I viewed this water purification process while simultaneously producing electricity it brought a huge smile to my face. It is a product that could bring a single solution to address a multitude of problems. Bravo! I truly wish this lady Eden Full the best of luck. Great job!

Eden Full's technology was built from developing a low-cost rotating tracker for solar panels, based on a simple but ingenious mechanism.
Bottles full of water are attached to the solar panel with a counterweight to the other side. The water then passes through a filter and goes to a receiving container, so the more water is filtered, the less it remains in the bottles. This make the solar panel rotate and follow the sun for maximum exposure, and so harnesses the most power.
The system increases solar panels’ energy output by up to 40%, by the end of the day producing at least 4 liters of clean water. “It’s a win-win,” underlines Jarnail SinghIndia Program ManagerThe Climate Group who leads the Bijli project. “The areas where our projects are deployed often have to struggle both with the lack of energy and clean water. This is a big improvement for their every day’s life, and can really help us to switch towards a clean, healthier use of energy.”
Since September, the company has deployed over 20 installations throughout India aiming to increase this number to 45 for the pilot phase. After that SunSaluter, with the help of The Climate Group and the Dutch Postcode Lottery, will gather the data to show how this innovative concept can be scaled up.
