Quick Answer
Regularly clean solar panels, especially during heavy pollen seasons, to maintain optimal energy production. Use a soft-bristled brush and water to remove loose debris. Avoid high-pressure washes that can damage panels.
Cleaning Solar Panels During Heavy Pollen Seasons
When dealing with heavy pollen, it’s essential to clean your solar panels more frequently to prevent pollen buildup. A dirty panel can reduce energy production by up to 35%. For a standard residential solar panel system, plan to clean the panels every 4-6 weeks during peak pollen seasons. Use a soft-bristled brush to gently sweep away loose pollen and debris.
Choosing the Right Cleaning Tools
When selecting a cleaning tool, choose a soft-bristled brush with nylon or polyester bristles. Avoid using brushes with metal or hard bristles, as they can scratch the panel surface. For more stubborn stains, use a mixture of water and a mild soap specifically designed for solar panels. Avoid using household cleaners or chemicals, as they can damage the panel coating.
Water Pressure Considerations
When rinsing the panels, use a low-pressure hose with a spray nozzle set to a gentle fan tip. Avoid using high-pressure washes, which can damage the panel’s sealants and compromise the waterproof coating. A low-pressure wash with a flow rate of 15-20 gallons per minute is sufficient for most residential solar panel systems.
