Don’t Overlook Solar Snow Management


As another year comes to a close, we can’t help but reflect on the past, while also looking forward to the future.

For us here at Alpine, 2019 saw a big increase in the use of our solar snow management systems all across the U.S. and Canada. We look forward to what 2020 will bring!

Why the big increase? Well, firstly, more and more people are going solar, so there are more solar arrays installed than ever before. Secondly, the more solar installed in areas that receive any amount of snow fall, the more solar customers are noticing the liability of snow and ice avalanching off their panels, to the ground below, putting your gutters and things at ground-level like cars, landscaping, pets, ground mounted mechanicals and most importantly, people, directly in harm’s way.

Why are solar snow avalanches so common?

Let’s take a look at the roof surface – in this case, solar panels. The snow that would’ve accumulated on your roofing material has instead accumulated on your solar panels – which, as you know, are fabricated from glass. And it goes without saying (but I’m going to say it anyway): glass is frictionless. The melting snow on your panels actually 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.  

What’s the solution?

As far back as 2010, Alpine SnowGuards began receiving calls asking if we had a “snow guard” or “snow retention” solution to address issues that contractors were incurring. Initially we suggested using one of our stock products, like the PP125 or PP225 (PP125 shown below) for installations on composition shingle roofs below the array.

The biggest difficulty with using traditional snow guards is that an entire tier of panels is sacrificed at the eave edge of the roof. As a result, we set out to engineer a frame-mounted solar snow management device.

The results of this project? These systems have been in service since 2012.

With well over HALF A MILLION FEET of these systems in service on both residential rooftops and commercial/PV canopy/carport projects, this is an extreme-winter-condition, time-tested, performance-proven product.
