How to Clean Solar Panels in Singapore

Introduction

Singapore's tropical climate, combined with high humidity and occasional bird droppings, can significantly impact solar panel efficiency. Regular cleaning is essential to maintain optimal performance and ensure maximum energy production. This guide will provide you with effective methods for cleaning your solar panels in Singapore.

Cleaning Frequency

  • Monthly: For general maintenance and to remove dust and pollen.
  • More frequently: During periods of heavy bird activity or after storms.

Cleaning Methods

  1. Hose Down:
  • Use a gentle spray from a garden hose to remove loose dirt and debris.
  • Avoid high-pressure settings that can damage the panels.
  1. Soft-Bristled Brush:
  • For stubborn dirt or bird droppings, use a soft-bristled brush to scrub gently.
  • Avoid using harsh chemicals or abrasive materials that can scratch the panel surface.
  1. Dish Soap Solution:
  • For persistent stains, mix a mild dish soap solution with warm water.
  • Apply the solution using a soft cloth or sponge, and rinse thoroughly with clean water.

Safety Precautions

  • Turn off the system: Before cleaning, ensure the solar system is turned off to prevent electrical hazards.
  • Avoid harsh chemicals: Avoid using strong acids, alkalis, or abrasive cleaners that can damage the panel surface.
  • Wear protective gear: Consider wearing gloves and safety glasses to protect yourself from potential hazards.

Additional Tips

  • Inspect for damage: While cleaning, inspect the panels for any signs of damage, such as cracks or broken glass.
  • Check for shading: Ensure there are no obstructions, such as trees or buildings, shading the panels.
  • Professional cleaning: If you're unable to clean the panels yourself or if they require extensive cleaning, consider hiring a professional solar cleaning service.
