Feature: Remove stagnant water automatically. Increase power generation to prove the service life of solar panels. Easy installation. Fasten the frame of the solar panel automatically. Solar Panel Cleaning Clip is a rectangular self-adhesive polymer strip containing a water-inducing agent. Simply stick to the frame of the photovoltaic module, there is no need to make adjustments to the components. In case of rain, the sludge water collected at the bottom of the frame is automatically directed over the frame and discharged and discharged in the stage of sludge water formation! Through tests, it was found that the water accumulation and dust accumulation along the boundary of the components of the sludge belt was essentially eliminated after the installation of the water guide adhesive, the power generation gain increased from 2% to 10%.
