Centralized photovoltaics and distributed photovoltaics emphasize the difference in installation scale and methods, but in fact, the design and location of the modules are also very different.

      Most of the centralized photovoltaic power generation equipment is located in areas with sufficient light (such as the northwestern region), and there are independent large-scale centralized inverters. The module structure is usually divided into five layers, namely photovoltaic glass, adhesive film, solar cell, adhesive film and back sheet. After years of application, mature products and solutions have been developed.

      But in distributed photovoltaic, this kind of scheme is not suitable, must consider indoor lighting, especially BIPV, opaque solar cell backplane is not suitable.

      This requires the use of more efficient double-sided double-glazed modules that have been favored by the industry in recent years. These modules are generally regarded by the industry as a useful means to reduce costs and improve efficiency, and will explode in the short term. . However, in centralized photovoltaics, the development of double-sided double-glazed modules did not meet expectations.

      Distributed photovoltaics require double-sided double-layer glass components, and the use of photovoltaic glass instead of solar cell backplanes not only improves weather resistance, but also solves the problem of indoor lighting. Of course, this will also increase the demand for photovoltaic glass, which is beneficial to photovoltaic glass companies. This is one of the reasons why many companies have recently entered photovoltaic glass.
