Quick Answer
Inspect solar panels every 2-3 days during heavy snowfall, or as soon as possible after the snowfall has ceased, to ensure optimal performance and prevent damage.
Understanding Snow Load
Heavy snowfall can accumulate on solar panels, causing them to become weighed down. This can lead to damage to the panels, racking system, and even the roof or ground where they are installed. It’s essential to understand the snow load capacity of your solar panels, which is typically between 20-50 pounds per square foot, depending on the manufacturer.
Inspecting and Clearing Snow
When inspecting solar panels during heavy snowfall, look for any signs of damage or stress on the panels, racking system, or surrounding structures. Check for any broken or loose connections, and ensure that all screws and bolts are securely tightened. Use a snow rake or broom to clear snow from the panels, working from the top down to avoid scratching the surface. Be cautious not to apply too much pressure, which can cause damage to the panels or racking system.
Best Practices for Snow Load Management
To minimize the risk of damage from snow load, consider installing snow guards or roof rake systems that can help prevent large amounts of snow from accumulating on your solar panels. You can also use a snow load calculator to determine the maximum amount of snow your panels can safely handle. Regularly inspecting your solar panels during heavy snowfall and taking prompt action to clear snow can help ensure optimal performance and extend the lifespan of your solar array.
