When installed, due to the slight projection of the edge of the panels, stagnant water may not drain properly, leading to sediment buildup that can soil the edges or corners of the modules. Accumulation of dirt on panel edges or corners can negatively impact the performance of the photovoltaic system, reducing power generation and potentially causing hot spots, which may shorten the panel's lifespan. The PV panel water drainage clip is a self-fastening clip made of plastic. It measures approximately 68 mm in length, 8 grams in weight, and is designed to fit various panel frame thicknesses. Available in 35 mm width, the clip attaches to the bottom edge of the PV panel, allowing water to flow off smoothly and helping prevent dirt accumulation. Installation instructions: 1. Clean the entire surface of the PV panel before installation. 2. Attach the water drainage clip to the bottom edge of the panel, ensuring it is securely fastened and not tilted. 3. Proper installation helps prevent stagnant water and reduces the risk of soiling. To avoid damaging the panel glass during installation, consider using a photovoltaic panel protection mat. Note: If the solar panel already has dirt or residue, clean it thoroughly before installing this product. This product is designed to help prevent the formation of new deposits, not remove existing ones.
