The first patent-pending Solar Snow Management System™ designed by snow retention industry specialists, Alpine SnowGuards, specifically for solar panel installation, made in the U.S.A. Solar Snow Pads add friction to a frictionless surface, allowing snow and ice to melt off the panel in a managed fashion. Can be used on new or retrofit installations. EcoFasten Solar.
The calculated snow load of a solar panel is approximately 800 lbs/panel (50 lbs/sf x 16 sf ave. panel). Solar panels (by their nature glass/hard roof surface, no friction) allow built up snow to release in an avalanche manner, with the potential to cause serious injury, damage or even death.
This system is designed to clamp to the solar panel frame, does not penetrate or scuff the frame and, more importantly, does not shade the collector surface. This patent-pending design (already being used on panel installations January 2013) offers the flexibility of being used as a pad-style, pipe-style or both. The Solar Snow Pad allows snow and ice to melt and slowly slide off the panel's surface in a managed fashion, instead of releasing suddenly, like an avalanche. This small but highly-effective device utilizes a "T" nut clamping design that will fit between panels set as close together as 1/8-inch. Moreover, the Solar Snow Pad can be installed with ease during the initial array installation or can be retrofit into an existing system.
How does the Solar Snow Management System™ work using Solar Snow Pads?
Solar Snow Pads add friction to a frictionless surface, allowing snow and ice to melt off the panel in a managed fashion. Snow accumulation on a solar panel will build up against, slump, and then slide off the Solar Snow Pad. Snow will fall from one pad and hit against another pad attached to the array lower on the roof. Solar snow retention cannot be used in areas with over 50 lbs. ground snow load.
What about shading?
Solar Snow Pads are designed to measure 1 ¼” off roof surface to prevent shading. Some shading will occur during the solstice, although not during the hours of collection. Rods cause very little shading making them an add-on option where a greater barrier is needed.
What style works best?
In some cases Solar Snow Pads may not be enough. A “barricade” system may be needed if any snow falling off the roof creates a dangerous situation. (Example: egress)
For optimum snow management - choose a solar snow barricade design. For optimum solar panel function - choose a solar snow pad.
