Quick Answer
Common Mistakes When Installing Solar Panels In Snowy Areas are not accounting for the increased weight and risk of snow load, and failing to use snow-clearing or self-cleaning systems to maintain panel efficiency.
Assessing Snow Load Requirements
When installing solar panels in snowy areas, it’s essential to assess the local snow load requirements. This involves determining the weight of snow that can accumulate on the panels and ensuring the system can withstand it. The International Building Code (IBC) recommends a minimum snow load of 20 pounds per square foot (psf) in areas with moderate snowfall, and up to 40 psf in areas with heavy snowfall. To determine the correct snow load for your installation, consult local building codes and consider factors like roof pitch, panel orientation, and surrounding terrain.
Designing Snow-Clearing Systems
To mitigate the impact of snow on solar panel efficiency, consider designing snow-clearing systems into your installation. This can include using snow-clearing panels or photovoltaic (PV) panels with built-in snow removal systems. One option is to use a snow-clearing panel with a tilting mechanism that allows snow to slide off the panel surface. For example, the “snow-shedding” panel design by SunPower features a unique angle and texture that enables snow to slide off easily, reducing the risk of snow load-related damage.
Installation and Maintenance Considerations
When installing solar panels in snowy areas, it’s crucial to consider the potential for snow accumulation and ensure the system is designed and installed to withstand it. This includes using sturdy mounting systems, securing panels to the roof or ground, and ensuring the electrical system is protected from moisture and snow-related damage. Regular maintenance is also essential to ensure the system remains efficient and effective throughout the year. This includes cleaning snow and debris from the panels, checking for damage or wear, and performing routine electrical inspections.
