Managing Snow on Solar Arrays: It’s What We Know

Does your roof sport a solar array? If the answer is yes, congratulations! It’s one of the best investments you’ll ever make, and the ROI can’t be beat. When it comes to managing snow on solar arrays, you’ve come to the right place. Alpine SnowGuards has been an industry leader in rooftop snow management for over 20 years. We manufacture the first and only snow management systems for solar arrays on the market. 

Solar Snow Research & Development

We’ve been involved with solar snow management R&D for the better part of 10 years now. Some of the biggest installers in the country rely on our solutions to mitigate the risk of a solavalanche. Yes, a solavalanche – snow avalanching off your solar panels, putting people, pets, cars, landscaping, gutters, you name it, in harm’s way.

Low Profile Design to Minimize Shading

The final designs were engineered specifically to provide a super low profile to minimize shading. Because the majority of panels don’t generate electricity along the edges, the shading effect is extremely minor.

How does a solavalanche occur in the first place? Well, the snow that would’ve accumulated on your roofing material has now accumulated on your solar panels. Solar panels are fabricated from glass and glass is frictionless. The melting snow on your panels acts as a lubricant between the snow mass and the panel surface, resulting in the perfect scenario to allow that snow mass to come barreling off your roof.

Solar Snow Management Options & Free Recommended Layouts

So, what can you do? Start by taking a look at the below solar snow management options, then send us your information and we’ll provide you with a free recommended layout.

Solar SnowMax-R2 (fence-style for use on the eave edge of your array – project image from NRG Home Solar, Long Island, NY)


Solar SnowMax-Standard (for additional up-slope rows, also fence-style – project image from Go Green Industries, Westford, MA)


 (For use on additional up-slope rows, Solar Snow Pad pad-style solar snow guards also accept two optional 3/8” OD rods, resulting in a hybrid solar/pad/pipe-style snow management system).


Note: since the time of this writing, Alpine has innovated new products into our solar snow management system including the Solar Snow Dog. The Snow Dog is a 6″ pad-style developed in response to customer demand for a more extended version.
