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, reduce power generation, and contribute to hot spot formation, 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, weighs 8 grams, and the width is designed to fit the thickness of the panel’s aluminum alloy frame. Available in 35 mm size, the clip attaches to the bottom edge of the PV panel, allowing water to flow off smoothly and helping prevent dirt accumulation. Installation instructions: First, clean the entire surface of the PV panel. Attach the water drainage clip to the bottom edge of the panel, ensuring it is securely fastened and not tilted. Proper installation helps prevent water stagnation and dirt buildup. To avoid stepping on the panel glass during installation, consider using a photovoltaic panel protection mat. Note: If the solar panel already has accumulated dirt or residue, it must be cleaned before installing this product. This product is designed to help reduce the formation of new dirt deposits along the edges.
