When installed, due to the slight projection of the edge of the panels, stagnant water may not drain properly, causing mud to accumulate and soil the edges or corners of the modules. Dirt buildup 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. Available in 35 mm size, the clip attaches to the bottom edge of the PV panel, allowing water to flow off efficiently and helping prevent fouling. Installation: Clean the entire surface of the PV panel before installation. Attach the water drainage clip to the bottom edge of the panel, ensuring it is not tilted. Proper installation helps avoid the formation of mud accumulation zones. To prevent damage to the panel glass during installation, use a photovoltaic panel protective mat. Note: If the solar panel already has accumulated sludge, it must be cleaned prior to installing this product. This product is designed to help reduce the formation of new sludge buildup.
