Photovoltaic module construction The conventional module consists of glass + EVA + photovoltaic cells + EVA + backplate.

The mainstream photovoltaic backsheet is a TPT material composed of two fluorine films and an intermediate PET film. Among them, the fluorine film is only produced by DuPont, the production capacity is limited, and the price is high, making the total cost of the photovoltaic backplane fall into a limited space.

We believe that two related technologies that are worth paying attention to at the moment are: plating anti-reflective film glass and double-glass photovoltaic modules, respectively replacing conventional glass and photovoltaic backsheets.

Using the mainstream 230W polysilicon photovoltaic module as an example, according to the current price of US$1/W PV module price and the coating film cost data obtained recently, it was found that the module coating can increase the gross profit margin of the PV module plant, and the gross profit margin remains basically unchanged.

It is expected that there will be limited space for falling prices of PV modules in the next 3-6 months, and the cost of coating will be lowered as the production capacity of major manufacturers expands, making the coating of modules more economical.

On behalf of the coating companies are: AMD, Xiuqiang shares, CSG A

Component companies adopt coating conditions: Suntech 100%, Hanwha majority, Tianhe and Yingli just started, Hairun, etc. have not yet been adopted. We expect domestic companies to have a coating capacity of less than 30%. In the future, as the coating economy becomes more pronounced, the market share of coated components is expected to converge to 80-100%.
