When mechanical vibration is applied to the panel surface, water droplets are directionally conveyed along tracks of rungs at speeds of up to 27 mm per second, collecting and removing surface.
With this in mind, this study introduces a novel hot knife method to efficiently separate and recover the back sheet layer from c-Si PV modules, a primary source of toxic gases during thermal treatment. A thin and highly conductive knife was selected for the hot knife-cutting process.
Cutting removes PV sheet sections by application of a blade, typically a hot knife or wire. The hot knife or wire may be heated up to 200 ℃, a temperature which can adequately soften the encapsulant layers (ethyl vinyl acetate or EVA) [64], [136]. Cutting involves some precision as the hot cutter is inserted into the encapsulant layers [69 .
Researchers at Scotland’s Heriot-Watt University have developed a waterless self-cleaning technology for PV panels which involves vibration to remove dust and sand by exciting fundamental .
As the photovoltaic (PV) industry continues to evolve, advancements in The role of vibration knife in cutting photovoltaic panels have become critical to optimizing the utilization of renewable energy sources. From innovative battery technologies to intelligent energy management systems, these solutions are transforming the way we store and distribute solar-generated electricity.
