SOLAR PANEL CLEANING RESOURCES

IS IT TIME FOR A SOLAR PANEL CLEANING?

The short answer is to do a solar panel cleaning whenever they need it. That can be when you notice a drop in production (5-10%), or you see visible build-up of pollen, dirt, dust, or plant material.

As a rule of thumb, we recommend cleaning your solar panels twice per year, once at the start of summer to clear off any spring pollen/debris, and once towards the end of summer to remove any dust that built up over the summer months. When it’s time to clean your panels, we have a list of recommended companies, or you can do it yourself if you prefer!

CLEANING SOLAR PANELS YOURSELF

Cleaning your own solar panels can a simple, but delicate process. As long as you follow these simple instructions and are careful not to scratch the panels while cleaning, you should be thrilled with the result.

 

YOU’LL NEED JUST A FEW KEY ITEMS TO COMPLETE THE JOB

  1. Car wash brush or microfiber cloth
  2. Dawn soap – optional
  3. Hose (not a pressure washer)

CLEANING PROCESS

  1. Spray panels with a low pressure hose to remove any large debris. Sometimes this step alone is enough to remove debris
  2. Mix a mild soap solution (a few drops per gallon), and gently scrub it onto the panels with the car wash brush or microfiber cloth
  3. Rinse the soap solution off using the same low pressure hose, and repeat as needed.

THINGS TO AVOID

  • Don’t use a pressure washer to clean your panels, as the higher pressure can cause scratches and work debris further into the panels’ structure.
  • Don’t use harsh chemicals, as these can damage the coatings and sealants on the panels
  • Don’t scrub vigorously, or use abrasive tools, as these can scratch or damage the panel’s surface
  • Don’t climb on the panels, as they are slippery even when dry, and can be damaged by excess weight
