Your solar panels have been professionally installed, now what?
As a proud solar panel owner in Calgary, you want to ensure your investment is generating the maximum amount of energy possible. One crucial aspect of solar panel maintenance is cleaning, but is it worth it? In this blog post, we’ll explore the importance of solar panel cleaning, how often it should be done in Calgary, and whether you can do it yourself or need professional help.

Is Solar Panel Cleaning Worth it?

Dirty solar panels can reduce energy production by up to 28% and increase the risk of damage. Dust, dirt, and debris can accumulate on the panels, blocking sunlight and causing the system to work harder, leading to increased wear and tear. Cleaning your solar panels regularly can help:

  • Increase energy production
  • Extend the lifespan of your solar panels
  • Reduce maintenance costs
  • Prevent damage from dirt and debris

How Often Should Solar Panels be Cleaned in Calgary?

The recommended cleaning frequency for solar panels in Calgary depends on various factors, including:

  • Weather conditions: Calgary’s dry and windy climate means panels may need more frequent cleaning.
  • Panel angle: Panels installed at a steeper angle may require less cleaning.
  • Surrounding environment: Panels near trees or construction sites may need more frequent cleaning.

As a general guideline, solar panels should be cleaned:

  • Every 6 months for panels installed at a shallow angle (<30°)
  • Every 12 months for panels installed at a steeper angle (>30°)

Can I Clean My Solar Panels Myself?

Yes, you can clean your solar panels yourself, but it’s essential to take necessary precautions:

  • Use a soft-bristled brush or sponge to avoid scratching the panels
  • Use a mild cleaning solution and avoid harsh chemicals
  • Avoid using high-pressure washing or abrasive materials
  • Ensure the panels are cool and dry before cleaning

However, consider the following:

  • Safety risks: Cleaning solar panels can be hazardous, especially if you’re not comfortable with heights or ladders.
  • Equipment requirements: You may need specialized equipment, such as a water-fed pole system, to reach and clean the panels effectively.

Do Solar Panels Need Special Cleaning in Calgary?

While you can clean your solar panels yourself, hiring a professional service has its advantages:

  • Expertise: Professional cleaners have the necessary training and experience to clean your panels safely and effectively.
  • Specialized equipment: Professional cleaners have access to the right equipment for the job, ensuring a thorough and efficient cleaning process.
  • Safety: Professional cleaners take necessary safety precautions to avoid accidents and injuries.


Solar panel cleaning is an essential aspect of solar panel maintenance in Calgary.
