Are Ground-Mounted Solar Panels Better For Snowy Locations?

Understanding Snow Load on Solar Panels

When it comes to snowy locations, the primary concern is the snow load on solar panels. A snow load of 20 pounds per square foot is considered moderate, while 40 pounds per square foot is considered heavy. Ground-mounted solar panels can withstand snow loads better than rooftop installations due to their design and orientation. A 15-degree tilt is ideal for snow-shedding properties, allowing snow to slide off the panels more easily.

Snow Shedding Techniques for Ground-Mounted Solar Panels

To enhance snow shedding on ground-mounted solar panels, several techniques can be employed. Using a 5-10 inch standoff to elevate the panels can increase snow shedding efficiency. Additionally, a 15-degree tilt and a 20-30 inch overhang can also contribute to better snow shedding. These techniques can help reduce the risk of damage to the panels and increase their lifespan in snowy locations.

Choosing the Right Ground-Mounted System for Snowy Locations

When selecting a ground-mounted solar panel system for a snowy location, choose a system specifically designed for high snow loads. Consider a system with a robust frame and a snow load rating of at least 60 pounds per square foot. It’s also essential to choose a system with adjustable tilt and orientation to ensure optimal snow shedding. A system with a tracking feature can also help maximize energy production during periods of low snow cover.
