Cleaning instructions

Solar panel modules are designed to have a long service life.

Normally, solar panel modules are kept free of dirt such as dust and leaves or similar soiling by wind, rain and snow. However, this natural cleaning effect may not work sufficiently due to soiling such as bird droppings, low pitch, extreme location in industrial
or agricultural environments, and it is thus advisable to clean the system regularly in order to achieve the optimal yields and ensure the service life of the system.

In general, clean with treated water and a soft cloth or sponge.
Impurities such as drilling dust or mortar residues on coated or bare aluminium parts must be removed immediately.
Do not scrape off dirt dry or use harsh cleaning agents.
Do not use a high-pressure cleaner under any circumstances.
Do not use materials such as aggressive chemicals, abrasives, blades, steel wool, polishes, etc. They can damage the glass surface. This will void the warranty.
Subsequent application of water-repellent or dirt-repellent coatings can have a negative impact on the efficiency of the solar panels and thus on the yield.

PREFALZ solar panels should only be cleaned by qualified personnel. The manufacturer’s guidelines must be observed.
