What is a solar panel snow guard?

A solar panel snow guard is a physical barrier you can install in between or on the edges of your solar panels. It's designed to prevent the mini avalanches that can occur when you install rooftop solar. Solar snow guards catch snow sliding off of your panels, which keeps them from falling all at once.

Do solar panels work if it snows?

Snowy winter often means less solar energy production, but with effective solar panel snow removal, you can maintain good efficiency. Did you know that even during cold months, solar panels can still generate about 50 to 80 percent of their maximum output? How can you ensure they perform at their best? Removing snow is key.

Can solar panels withstand heavy snow?

Don’t Ignore Heavy Snow: Do not let heavy snow accumulate on your solar panels for too long, as it can significantly reduce efficiency and potentially cause damage. Your solar panels rely on photovoltaic (PV) cells, located in the front layers, to capture sunlight and convert it into electricity.

Does snow slide off solar panels?

Snow doesn’t always slide off solar PV panels, and flat roofs and wet snow are variables. In the US, the snow load is typically between 20 and 40 psf. Only four inches of wet snow weighs over eight psf. To calculate snow load, you must know the climate, roof pitch angle, and the altitude of your location.

How do I choose a snow guard for my solar panels?

As you choose your new solar panels, be sure to talk to your provider about complimentary snow guard options for the best result. There are two general types of snow guards: Clamp-on guards and snow fences. Clamp-on snow guards can be installed at the edges of your solar panels, or in between panels.

Are solar panels slippery if it snows?

But when solar panels are installed on the roof, those large panels of glass diminish friction and are rather slippery. As snow collects on your solar panels, it may become compacted. And, as melted snow slowly begins to run between your solar panels and that compacted snow, it can slide off in dangerous avalanches.
