Features: 1. Automatically remove accumulated water 2. Increase power generation to improve the service life of solar panels. 3. Easy to install. Automatically snap on the solar panel frame. 4. Polymer material, anti-aging, high/low temperature resistance, long-term outdoor use Notice: If the solar panel already has sludge, it must be cleaned before installing this product. This product only reduces the generation of new sludge belt.<br><br>Description: Product name: Solar panel mud discharge clip Specifications: 40mm Clasped the water clip to the bottom edge of the PV panel, the stagnant water will flows away, there is no fouling again. When it rains, due to the slight projection of the edge of the panels, the stagnant water is not drained away in time, and the mud in the stagnant water precipitates to soiling the edges or the corners of the modules. The accumulation of dirt in the panels edge or in the corners, can have dramatic consequences on the proper functioning of the photovoltaic system, it reduces photovoltaic panel power generation, and will form hot spots effect, reducing the service life of panels How to install: First, make the whole surfaces of the PV panels clean, and clasped the water clip to the bottom edge of the panels , and don't tilt it, so it is ok, if it rains again, there will be no mud zone. In order to prevent stepping on the panel glass, you can use the photovoltaic panel protection mat. Material: plastic colour: black<br><br>Package Contents: 30 x solar panel mud removal clip<br><br>Only the above package content, other products are not included.
