Best Solar Panel Cleaning Equipment

Using the right solar panel cleaning equipment is crucial for maximizing the efficiency and lifespan of your solar system. In this comprehensive guide, we’ll explore the importance of keeping solar panels clean, the best cleaning tools available, and how to use them effectively.

Why Solar Panels Should Be Kept Clean

Did you know that dirt and pollution can reduce the efficiency of your solar panels by up to 25%? Regular cleaning is essential to maintain high efficiency levels and save on energy production and potential repairs.

5 Essential Pieces of Solar Panel Cleaning Equipment

Cleaning solar panels is crucial for maintaining their efficiency and longevity. Here are five essential tools every solar panel owner should have for effective cleaning:

1. Ladder and Harness

Importance: Safety is paramount when cleaning solar panels, especially those installed on rooftops. A sturdy ladder and a safety harness are essential to prevent falls and injuries.

2. Squeegee

Function: A squeegee is ideal for removing water from the panels after cleaning. It helps in avoiding water spots and ensures a clean, clear surface for maximum sunlight absorption.

3. Non-Abrasive Solar Panel Cleaner

Recommended Type: Mild soap or a specialized non-abrasive solar panel cleaner is recommended to avoid damaging the panel’s surface. Harsh chemicals can corrode the panels and reduce their efficiency.

4. Soft-Bristled Solar Panel Cleaning Brushes

Usage: Soft-bristled brushes are perfect for gently removing dirt and grime without scratching the panel’s surface. They are especially useful for dislodging stubborn dirt.

5. Follow-Through Solar Panel Washing Brush

Advantages: This type of brush integrates irrigation with soft bristles, allowing for effective and efficient cleaning. It helps in simultaneously washing and brushing the panels, ensuring thorough cleaning.


Beware of inexpensive all-in-one solar panel cleaning kits. Corrosive liquids and poor-quality bristles can damage your solar panels. Always consult your installer before purchasing.

How to Use Solar Panel Cleaning Equipment

Before cleaning, always power down your solar system and inspect the panels for any damage. Use gentle methods to clean, avoiding high-pressure water and harsh chemicals.

Steps for Cleaning Solar Panels

  1. Remove Loose Materials: Use a brush to clear debris and bird droppings.
  2. Gentle Scrub: Use clean water and a non-abrasive cleaner.
  3. Rinse and Squeegee: Rinse the panels and dry them with a squeegee.
  4. Dry Panel Edges: Use a lint-free cloth for sensitive edges.

However, for larger installations or difficult-to-reach panels, professional services like Airis Energy offer the expertise and equipment to ensure safe and effective cleaning.

Remember, regular cleaning is not just about maintaining efficiency; it’s about protecting your investment in renewable energy. Choose the right tools and methods to keep your solar panels performing at their best.


1. How often should I clean my solar panels?

The frequency of cleaning depends on your location and the environment. Generally, it’s recommended to clean solar panels at least twice a year. However, in areas with more dust, pollen, or bird droppings, more frequent cleaning may be necessary.

2. Can I use regular household cleaners on my solar panels?

It’s best to avoid regular household cleaners as they can be abrasive or corrosive. Instead, use a mild, non-abrasive solar panel cleaner or simply a mixture of water and mild soap.

3. Is it safe to clean solar panels by myself?

Cleaning solar panels can be done safely if you take the proper precautions. Always use a sturdy ladder, a safety harness, and ensure that the electrical systems are turned off before cleaning. If your panels are difficult to reach or if you’re unsure about safety, it’s best to hire a professional.
