Snow accumulation atop photo voltaic panels causes power losses of between 5% and 15% each Winter in northern climates around the globe, with some heavy snowfall even resulting in mechanical hundreds that harm PV modules.
Preserving photo voltaic panels snow-free has been a pricey and inefficient proposition—till now.
Supplies and engineering scientists on the College of Toledo have developed an ingenious resolution that’s profitable awards and satisfying the demand of 150 photo voltaic plant operators of their newest pilot assessments.
The product is a novel strip that’s utilized to solely the decrease fringe of the panel, which causes the melting of the snow with out interfering with the absorption of daylight.
In a video demonstrating Snow-Free Photo voltaic, the Ohio innovators say the easy-to-apply strip “doesn’t trigger any partial shading or scorching spots on the panel and doesn’t invalidate module guarantee.” It may, in truth, enhance the life expectancy of the panels.
The versatile strip doesn’t require any power to function and the coatings are “extraordinarily sturdy, strongly adhering to the PV.”
“There isn’t a want for energy—it’s passive,” says Hossein Sojoudi, the Affiliate Professor and Technical Advisor who based Snow-Free Photo voltaic. “You apply it to the decrease backside and it really works from there.”

Tremendous simple to put in, the job might be executed by unskilled labor with no coaching.
The corporate isn’t offering technical specs due to ongoing competitors within the subject, however, up to now, “no identified failure mode (has) but to be recognized” over a number of winters of rigorous sturdiness assessments performed by a photo voltaic photovoltaic testing laboratory.
“We additionally confirmed that our strip coatings are sturdy throughout common cleansing of photo voltaic panels.
“Via strategic partnerships, we demonstrated scalable manufacturing of our product with month-to-month manufacturing fee of 60,000 strip coatings,” he added.
They expanded their pilot take a look at companions to extra areas and utility firms with 1000’s of anticipated installations by the top of 2023.
The information demonstrated greater than 3.4% and 5.1% annual enchancment in energy era in Massachusetts and Japan respectively.
With further direct gross sales to pilot take a look at companions and a payback time of two years, they estimate to achieve a manufacturing fee of 1 million strip coatings by the top of 2024.
“Our resolution is a game-changing know-how,” mentioned their enterprise adviser Dan Vining.
They are going to use funds gained within the American Made Photo voltaic Prize to rent new expertise and proceed their efforts to achieve 28 million utility scale panels within the eleven U.S. states with heavy snowfall.
That will result in a further $150 million in annual income—commercializing their product to “ship on the promise of photo voltaic power all yr lengthy.”
