How To Clean Solar Roof Panels: Tips from Trusted Solar PV Panels Manufacturers

Clean Solar Roof Panel

Introduction

Rooftop solar panels, sourced from trusted Solar PV Panels Manufacturers, are a sustainable solution for generating clean energy and reducing electricity bills, but they require proper care and upkeep. Dirt and debris build-up over time can reduce their efficiency. Regular cleaning and servicing are essential to maintain their performance and extend their lifespan.

This guide explains the importance of cleaning rooftop solar panels, when to clean them, and how to do it safely. Whether you are new to solar panels or want to improve their performance, this guide will help.

Why Do Roof Solar Panels Need Cleaning?

Solar panel efficiency, even in high-quality products from leading Solar PV Panels Manufacturers, is reduced by up to 20-25% due to bird droppings and grime blocking the sunlight. Bird droppings are particularly harmful and can cause stains if left uncleaned. Regular cleaning restores performance, improving solar panel efficiency, ensuring maximum energy output, and extending the panels’ lifespan. It also helps you save more money and get the best value from your solar energy system.

When Should I Clean Roof Solar Panels?

To identify the right time for cleaning rooftop solar panels, check for visible dirt, dust, or bird droppings on their surface. Reduced energy efficiency, shown on your monitoring system, can also indicate they need cleaning.

Seasonal changes can affect how often cleaning is required. For instance, summer brings dust and pollen, while winter may leave grime after heavy rain. Situational triggers like nearby construction, strong winds, or storms can also leave panels dirty and reduce their performance.

Regular checks and cleaning after such events will help maintain maximum efficiency.

What To Use For Cleaning Rooftop Solar Panels?

Use safe tools like a soft brush, sponge, or a hose with gentle spray when cleaning rooftop solar panels. Mild soap mixed with water or manufacturer-recommended solutions work best for removing dirt. Avoid abrasive tools, harsh chemicals, and high-pressure washers, as they can damage the panels or their protective coating. Using gentle methods ensures efficient cleaning, improving solar panel efficiency, and helping your panels perform better and last longer.

Steps For Cleaning Rooftop Solar Panels

Rooftop Solar Panel Cleaning

Step 1: Turn Off the Solar System
Switch off the solar power system to avoid electrical risks. While not mandatory, it is advisable for safety purposes during cleaning.

Step 2: Remove Dust and Debris
Start by using a soft, dry brush or mop to remove loose dust, leaves, and debris. This prevents dirt from sticking when water is applied. Ensure the bristles are soft to avoid damaging the panels.

Step 3: Rinse the Panels with Water
Use a hose with low pressure to rinse away dirt, bird droppings, and other residues. Be mindful of water temperature to avoid cracking the glass due to temperature differences.

Step 4: Clean with Mild Soap Solution
Apply a mild soap solution with a soft sponge or brush to gently scrub areas with stubborn grime, such as bird droppings. Avoid harsh chemicals or excessive scrubbing to prevent panel damage.

Step 5: Rinse and Dry
Rinse off the soap solution with the hose. The tilt of the panels will drain most water, but gently wipe away any remaining moisture with a soft cloth to avoid stains.

Step 6: Check Performance
After cleaning, monitor the solar panel’s output to ensure it is improving solar panel efficiency and working at its best.

Step 7: Seek Professional Help if Needed
For heavy grime, insects, or complex maintenance issues, contact a professional or your solar panel dealer. Regular professional maintenance ensures panels remain efficient and last longer.

Safety Precautions For Cleaning Solar Panels

  • Turn Off the System: Always switch off the solar system to avoid electric shocks.
  • Use Proper Equipment: Use a stable ladder and wear a safety harness when working at heights.
  • Check Weather Conditions: Clean on cool, dry days; avoid rain, strong winds, or intense sunlight.
  • Handle Gently: When cleaning rooftop solar panels, use soft brushes, sponges, low-pressure water and avoid abrasive tools.
  • Avoid Harsh Soaps: Avoid harsh soaps as they can corrode the panel’s surface, reducing performance instead of improving solar panel efficiency.
  • Stay Alert: Be cautious of slippery surfaces, uneven roof edges, and secure all tools.
  • Avoid Stepping on Panels: Never walk directly on solar panels to prevent damage.

Conclusion

Cleaning rooftop solar panels is worth the effort as it boosts energy efficiency and extends their lifespan. Dirty panels can lose up to 25% efficiency, making regular maintenance essential. Proper cleaning prevents long-term damage and ensures optimal performance. While the process is simple and cost-effective, professional help can be considered for complex cleaning. Regular care protects your investment and maximises the benefits of solar energy, ensuring your panels deliver consistent, clean power for years to come.
