How To Clean Solar Cell Modules

Solar Cell Modules really don't require much maintenance. As long as you inspect them for damage and clean the panels a few times a year, your lights will last 10 years without replacement. Desert or high pollen areas may require more frequent cleaning of fixtures. Dirty solar panels full of dust and debris can cost between 15% and 25% of your energy production costs. Fortunately, solar panels are easy to clean using a few tricks:

First, check with the manufacturer of the solar panel or fixture. They may have specific cleaning recommendations.

Solar panels can get hot in direct sunlight, so try to clean them on a relatively cool day, whether it's early morning or early evening.

Usually, a quick spray with a garden hose is enough to get the job done. However, if you have a lot of dust and grime, fill a bucket or spray bottle with warm water and soap for a more thorough clean.

Don't use abrasive or detergent cleaners; you want to avoid scratching the glass.

Clean the surface of the solar panel with a soft cloth or sponge. You can use a soft scraper without cleaning the wiring underneath.

Good rain can clean your solar panels. However, this method works best when the panels are sloped like a roof.

If you do need to clean the panels on your roof, remember safety first and consider hiring a professional solar panel cleaner.

In addition, solar panels installed near sources of pollution such as highways, factories, and airports may need to be cleaned more frequently
