What Not to Do

Hose the solar panels down: This will leave hard water spots and mineral deposits on the photovoltaic solar panels, reducing the efficiency. It will not clean the solar panels very well as it just washes off some of the dirt. You could also crack the solar panels if you use cold tap water on the hot solar panels.

Use chemicals or detergents: using chemicals or detergents could damage the solar panels. It will also leave a residue, which holds onto dirt, reducing efficiency dramatically. Chemicals may also void your manufacturer’s warranty!

Use a Squeegee: The surface of solar panels is not smooth like glass. Some panels have a frosted glass feel. So, if you use a squeegee to clean solar panels the dirt and detergent will be settling in all the little groves while you squeegee off the top layer of dust and dirt.

Use a Pressure Washer: Never ever let anyone pressure wash your solar panels! This may rupture the solar seals and void your warranty.

Use a company that does not specialise in solar panel cleaning: Crystal Clear Solar specializes in solar panel cleaning! We do not wash windows, houses, roofs or clean gutters! Make sure the person working on your large investment has the proper knowledge and experience

What you should do…
You should either spend a lot of money on professional equipment and training seminars, or you should contact Crystal Clear Solar, and have them professionally cleaned.
