When cleaning solar panels, it is important to use the right cleaning methods and avoid certain substances that could potentially damage the panels. Here are a few things you should never use to clean solar panels:
Abrasive materials: Avoid using abrasive materials such as steel wool or scrub brushes with harsh bristles. These can scratch the surface of the panels and reduce their efficiency.
Harsh chemicals: Stay away from harsh chemicals like bleach, ammonia, or abrasive cleaners. These can cause damage to the protective coating of the panels and may leave residue that affects their performance.
Hard water: Using hard water or tap water with a high mineral content can lead to the formation of mineral deposits on the surface of the panels over time. These deposits can interfere with the panel's ability to absorb sunlight effectively.
Pressure washers: It's generally not recommended to use pressure washers to clean solar panels. The high-pressure water jets can be too powerful and may damage the delicate surface of the panels or dislodge their electrical connections.
Excessive force or weight: Avoid applying excessive force or placing heavy objects on the solar panels while cleaning. Too much pressure or weight can cause cracks or damage to the panels.
For cleaning solar panels, it's best to use a soft brush or sponge with mild detergent and water. Make sure to rinse off any soap residue thoroughly. Additionally, it's advisable to consult the manufacturer's guidelines for specific cleaning instructions tailored to your solar panel model.
