Quick Answer
Regularly inspect and clear snow from solar panels to prevent damage and optimize energy production. Assess the solar panel's design and location to determine the most effective snow removal strategy. Utilize a snow rake or brush to gently remove snow without damaging the panels.
Assessing Solar Panel Design
When evaluating solar panels for snow load, consider the panel’s angle, size, and material. A south-facing panel with a 30-degree angle is generally ideal for snow country. However, if the panel is too flat or too steep, snow may accumulate and cause damage. A snow load of 20 pounds per square foot (psf) is a common standard for designing solar panels in snow country. In areas with heavy snowfall, consider a higher snow load capacity of 30-40 psf.
Snow Removal Techniques
To remove snow from solar panels, use a snow rake or brush with soft bristles to gently sweep away snow. Avoid using sharp tools or high-pressure washes, which can damage the panels. For heavily snowed panels, use a ladder or a lift to access the panels safely. Remove snow in sections, working from the top down to prevent re-depositing snow onto clean panels. For larger solar arrays, consider investing in a snow removal system or hire a professional to clear snow.
Panel Design Considerations
When designing solar panels for snow country, consider using panels with a built-in snow shedding system or a tilted roof design. These designs help to shed snow from the panels more easily. Additionally, consider using panels with a snow load rating of 20-40 psf to ensure optimal performance in snowy conditions. It’s also essential to follow the manufacturer’s guidelines for snow removal and maintenance to prevent damage to the panels.
