Is winter maintenance necessary for ground-mounted solar arrays?

Ensuring Snow Removal and Ice Buildup Prevention

Ground-mounted solar arrays are exposed to harsh winter conditions, including heavy snowfall and freezing temperatures. It’s crucial to remove snow from the panels to prevent ice buildup, which can reduce energy production and even damage the panels. A snow load of 20-30 pounds per square foot can be excessive for solar panels, and accumulation of 6-12 inches of snow can reduce energy output by 50-75%. Regular snow removal, ideally within 24-48 hours of a snowfall, is essential to maintain optimal performance.

Proper Panel Cleaning Techniques

When cleaning snow from ground-mounted solar panels, it’s essential to use the right techniques to avoid causing damage. Use a soft-bristled brush or a specialized solar panel cleaning tool to gently remove snow, working from the top down to prevent scratching the panels. Avoid using high-pressure washes, abrasive materials, or sharp objects that can damage the panel surface or the mounting system. For ice buildup, use a warm water and a gentle cleaning solution to prevent damage to the panel’s electrical connections.

Regular Inspections and Monitoring

Regular inspections and monitoring of ground-mounted solar arrays during winter are crucial to ensure optimal performance and identify potential issues. Check the mounting system for any signs of wear or damage, and inspect the panels for snow accumulation, ice buildup, or other issues that may impact performance. Monitor system performance and adjust snow removal schedules as needed to maintain optimal energy production.
