Quick Answer
Walking on solar panels covered in snow can be hazardous due to the risk of cracking or breaking the panels, which may lead to reduced energy output or expensive repairs.
Risks of Walking on Snow-Covered Solar Panels
When snow accumulates on solar panels, it can weigh heavily, potentially causing damage to the panel’s frame, glass, or electronic components. Walking on these panels can exacerbate this risk, as your weight can apply additional pressure, increasing the likelihood of damage. For a standard residential solar panel, a load of about 20 pounds per square foot can be catastrophic.
Safe Alternatives for Accessing Snow-Covered Panels
To avoid potential damage, consider using a ladder or a sturdy roof rake to gently remove snow from the panels. For taller installations, a snow-removal tool or a long-handled brush may be more suitable. Ensure that any cleaning tool has a secure grip to prevent slipping, and always maintain three points of contact with the ladder.
Maintenance and Safety Considerations
Regular maintenance can help minimize the risk of damage from snow. Install a snow-load monitoring system to alert you when the weight becomes excessive. Additionally, consider installing solar panels with a higher snow-load capacity, such as those rated for 60 pounds per square foot or more. Always follow the manufacturer’s guidelines for maintenance and repair.
