Features: 1. Automatically removes accumulated water 2. Helps improve solar panel efficiency and service life 3. Easy to install snaps directly onto the solar panel frame 4. Made of polymer material with anti-aging properties, resistant to high and low temperatures for long-term outdoor use Notice: If the solar panel already has dirt buildup, it must be cleaned before installing this product. This product helps reduce the formation of new dirt accumulation along the edges. Product Name: Solar Panel Water Drainage Clip Specifications: 30mm / 35mm / 40mm Attach the clip to the bottom edge of the PV panel; rainwater will drain away smoothly, preventing dirt buildup. During rainfall, water tends to stagnate due to the slight overhang of the panel edges. This stagnant water carries particles that settle and create dirt deposits on the edges or corners of the modules. Accumulated dirt can significantly affect photovoltaic system performance by reducing power output and potentially causing hot spots, which may shorten panel lifespan. Installation Instructions: Clean the entire surface of the PV panel before installation. Attach the drainage clip to the bottom edge of the panel without tilting. Once installed, future rainfall will not leave mud stains along the edges. To avoid damaging the panel glass during installation, use a photovoltaic panel protective mat. Material: Plastic Color: Black Package Contents: 30 x Solar Panel Water Drainage Clips Note: Light reflection and differences in display screens may cause slight variations between the color shown in the image and the actual product.
