When it rains, the slight projection of the panel edges can cause water to stagnate, leading to dirt accumulation on the edges or corners of the modules. This buildup may negatively impact the performance of the photovoltaic system by reducing power generation and potentially contributing to hot spot formation, which can shorten the panel's lifespan. The PV panel water drainage clip is a self-fastening plastic clip designed to attach to the bottom edge of the panel. With a length of approximately 68 mm and weighing 8 grams, the clip is compatible with aluminum alloy frames of varying thicknesses. By directing water away from the panel edge, it helps prevent dirt buildup and mud staining. Installation instructions: Clean the entire surface of the PV panel before installation. Attach the water drainage clip securely to the bottom edge of the panel without tilting. Once installed, the clip helps prevent the formation of muddy residues during rainfall. To avoid stepping on the panel glass during installation, consider using a photovoltaic panel protection mat. Note: If sludge is already present on the solar panel, clean the panel thoroughly before installing the clip. This product is designed to help reduce the formation of new dirt buildup only.
