Snow Falling From Solar Panels

This is the easiest and safest solution although it can take time for the weather to warm up enough to melt snow.

Snow falling from solar panels.

Solar panels can cause snow to slide off your roof in sheets. The snow fence extends high enough at the bottom edge of the panels to keep snow and ice from damaging property or people on the ground below. Snow has anti soiling properties and hence when it melts it takes with it any dirt on the panels. This also means that when the sun rises the snow can easily melt and slide off.

As snow falls on asphalt composition shingles snow and ice will tend to accumulate and cling to the shingles rough surface. Panels retain warmth and are often installed at an angle so when the storm blows over even heavy snow slides rights off. Most solar panels are installed at an angle and face the sun which helps the panels to absorb solar energy. Generally speaking solar panels are 20 c 36 f warmer than the ambient temperature.

As the snow and ice melts the resulting water runs down the roof below the frozen mass. It s a different story when heavy snow accumulates which prevents pv panels from generating power. So even a glimmer of sunlight can cause the solar panels to start warming up and hence hasten the melting of snow around it. Wait for the snow to melt.

The end result was a manufactured custom c22z standing seam snow fence that clamps onto the standing seam metal panel and wraps around the front edge of the solar panel to prevent snow from falling off the panel.
