●The combination property of Back sheet material plays an important role to photovoltaic

As everyone knows, most photovoltaic modules are exposed in the air in the environment like mountains, desert, seashore, farm and etc., affected by moisture, temperature, chemical gas, windy and dusty and etc. We have to make a strict control of the modules, materials and manufacture process to ensure a 25-year service. As the surface cover of modules, Back sheet shoulder a major responsibility. That’s why Toyo Aluminium K. K. attaches great importance to the combination property of Back sheet.
