Quick Answer
Using a squeegee on solar panel surfaces can potentially scratch the surface, especially if the squeegee is not specifically designed for cleaning solar panels or if excessive force is applied.
Risks of Squeegee Use
A squeegee can scratch solar panel surfaces if it has a rough or abrasive edge, which can cause micro-scratches that reduce the panels’ efficiency. This risk is particularly high for solar panels with a textured surface or those made of thinner materials. It’s essential to inspect the squeegee before using it on solar panels to ensure it won’t cause damage.
Safe Squeegee Alternatives
If you prefer using a squeegee, look for ones with a soft, rubber edge or specifically designed for cleaning solar panels. These squeegees are typically made of flexible materials that won’t scratch the panels. However, it’s still crucial to clean solar panels with a gentle touch and avoid applying excessive force.
Cleaning Techniques
When cleaning solar panels with a squeegee, start by spraying a cleaning solution onto the panel, then use the squeegee to gently remove dirt and debris. For tougher stains, use a soft-bristled brush to gently scrub the area before rinsing with the cleaning solution. Always clean solar panels in a shaded area to prevent water spots and ensure the cleaning solution dries quickly.
