Bonding of photovoltaic modules, junction box seal bonding, BEGINOR adhesives are commonly used in high-performance adhesives such as acrylic adhesives, polyurethane adhesives, modified epoxy resin adhesives, and silicone adhesives.

Photovoltaic power generation system Baigao adhesive application scheme

Photovoltaic power generation is a technology that directly converts light energy into electrical energy by using the photogenerated volt effect at the semiconductor interface. It is mainly composed of three parts: solar panels (components), controllers and inverters, and the main components are composed of electronic components. Solar cells can be encapsulated and protected in series to form large-area solar cell modules, and then combined with power controllers and other components to form photovoltaic power generation devices
