Regular maintenance not only ensures your panels generate the maximum amount of energy but also extends their lifespan and prevents costly repairs. Dust, debris, bird droppings, and even shade can significantly impact your system’s efficiency. 

By proactively addressing these issues, you can optimize your return on investment and enjoy the full benefits of your solar panels.

What’s the best way to clean solar panels?

While Australia enjoys abundant sunshine, it also presents challenges like dust, pollen, and even bird droppings. These can accumulate on your panels, hindering their ability to absorb sunlight and generate electricity. Here are some tips to keep your solar panels in Australia in their best condition:

1. Trim surrounding trees and vegetation:

Ensure your panels receive maximum sunlight by keeping them free from shade.

2. Check your inverter:

Regularly inspect your inverter for proper operation and clean its vents to prevent overheating.

3. Be aware of local regulations:

Some areas have specific regulations regarding solar panel maintenance.

How often should you clean your solar panels?

Ideally, aim for two professional cleanings per year, especially during spring and autumn when dust and pollen are prevalent. However, consider these factors for more tailored cleaning intervals:

1. Location:

Homes near dust sources like busy roads or construction sites might require more frequent cleaning.

2. Panel tilt:

Steeper tilts naturally shed debris, while flatter panels might need cleaning more often.

3. Rainfall:

Regular heavy rain can help naturally clean your panels, reducing the need for frequent professional cleaning.

DIY Solar Panel Cleaning ? Know Your Limits:

While professional solar panel cleaning is recommended, you can occasionally perform DIY solar panel cleaning between professional services. But remember, safety first!

Here’s how to safely clean your solar panels:

1. Wait for a cool, cloudy day:

Never clean your solar panels under direct sunlight, as it can cause burns or damage the glass.

2. Use soft, gentle tools:

Opt for a sponge or soft-bristled brush and a mild soap solution. Avoid harsh chemicals or abrasive materials.

3. Start from the top and work your way down:

This ensures dirt and debris don’t flow onto already cleaned areas.

4. Rinse thoroughly:

Use a garden hose with low pressure to remove all soap residue.

5. Stay safe:

Never climb onto your roof. If your panels are out of reach, utilize professional services.

Every 1-2 years, have a qualified solar technician inspect your system for potential issues and ensure everything is functioning optimally.


By following these simple solar panel cleaning tips, you can keep your solar panels humming along and generating clean, renewable energy for years to come. Remember, proper maintenance not only maximizes your investment but also ensures your system operates safely and efficiently.
