“In an advance that could dramatically improve the productivity of solar panels in cold climates, a University of Michigan-led team has demonstrated an inexpensive, clear coating that reduced snow and ice accumulation on solar panels, enabling them to generate up to 85% more energy in early testing.
The proposed coating solution is claimed to effectively melt ice and snow with temperatures down to -35 degrees Celsius. It is made of PVC or PDMS plastic and silicon or vegetable-based oils, which can be sprayed or brushed on in cold weather and, in its current iteration, can keep shedding snow and ice for up to a year.”
