Passive snow removal method developed to clear snow from PVs
A team of researchers from the University of Toledo invented Snow-Free Solar that can passively remove snow from solar panels and keep them functioning through the winter months.
In this paper, a domino-like snow removal system (DSRS) based on photovoltaics self-heating (PVSH) was designed and investigated to overcome this application challenge. The domino-like snow removal strategy is first proposed, whose core idea is to use the energy from uncovered PV modules to accomplish snow removal in PV systems string by string.
Here's the key idea most blogs miss: The easiest way to remove snow from solar panels is to let physics do the work. Automatic snow removal is built into the system before installation—not added later with tools.
However, a team of researchers from the University of Toledo in the United States invented a form of novel strip called Snow-Free Solar that can passively remove snow from solar panels and keep them functioning through the winter months. The team conducted tests on 150 solar plant operators by applying the strip to the lower ledge of the panel.
It is also feasible to use utility power for rapid snow removal when solar radiation is weak or fluctuant in grid-connected PV systems. The proposed DSRS brings new ideas and research directions for the future development of snow removal methods for PV systems.
