Can Solar Panels Be Installed On Ground Mounts In Snow-Prone Areas?

Design Considerations for Snow-Prone Areas

When installing solar panels on ground mounts in snow-prone areas, it’s essential to consider the weight and accumulation of snow on the panels. A general rule of thumb is to design the system to withstand a minimum of 2 pounds per square foot (9.8 kg/m²) of snow load, but this can vary depending on local building codes and regulations. A snow load calculator or a structural engineer can help determine the required design strength.

Choosing the Right Ground Mounts

To accommodate snow loads, ground mounts need to be designed with sturdier and heavier frames, often using reinforced steel or aluminum. Typical ground mounts have a load capacity of around 20-30 pounds per linear foot (29-44 kg/m), but this can be increased to 50-60 pounds per linear foot (74-88 kg/m) or more to accommodate heavy snow loads. Some ground mounts also come with adjustable legs to level the system and ensure proper panel alignment, even in areas with significant snow accumulation.

Panel and Mounting System Selection

When selecting solar panels for snow-prone areas, look for models with a high snow load rating, typically 5400 Pa (70.6 psf) or higher. These panels are designed to withstand heavy snow loads and maintain their structural integrity. Additionally, consider using a mounting system with a high load capacity and adjustable features to ensure the panels remain securely in place, even in extreme weather conditions.
