Domestic PVDF film for Photovoltaic grid parity

Abstract:

Photovoltaic (PV) grid parity is the dream of every PV practitioner and its PV generation cost is most important. In order to promote the decreasing of the PV cost, the choice of backsheet is critical, in which the choice of the outer film of Backsheet is particularly critical.

 

The premise of PV grid parity is the realization of the expectancy life of PV station and Using fluorine film for backsheet outer layer guarantee more than 25 years lifetime of PV station, no matter PVF and PVDF film, no matter imported or domestic film. Besides, the price of photovoltaic modules and auxiliary materials continues to decline, the high cost of some imported fluorine film has been unable to meet the cost requirements of PV station. From these two aspects, to meet the fluorine film cost-effective requirements the PV station, we must use domestic PVDF film as the a 25-year protection film for PV station.

Till now, PV station holders, especially large power investment companies still do not approve domestic fluorine film, but only permit two imported fluorine film, including PVF and PVDF. In response to this situation, the fluorine film, especially the domestic PVDF film, has been studied detailed from the development of global fluorine film industry, fluorine film processing technology and fluorine film weathering principle.

 

In this paper, the fluorine film industry for PV and the behind story of various views about fluorine film were interpreted. And the domestic PVDF film development status and trends were also described for perspectives of the development of the industry and fluorine film technology, thus explain the doubt of PV power plant practitioners and promote the domestic PVDF film to make a contribution to the PV grid parity.

报告摘要：

 

       光伏发电平价上网是我们每个光伏从业者的梦想，要实现光伏平价上网，光伏发电的度电成本是关键。为保障光伏发电度电成本的降低，光伏背板的选择非常关键，其中背板外层膜的选择尤为关键。

 

       光伏发电平价上网的前提是光伏组件寿命达到预期，即保障光伏组件至少25年寿命，因此外层必须要用氟膜，无论是PVF还是PVDF薄膜，无论是进口还是国产。另一方面，光伏组件以及配套辅材的价格在持续下降，某些进口膜的高成本已经无法满足光伏发电对成本的要求。从这两个角度考虑，要满足光伏电站对氟膜的高性价比要求，必须要选用国产氟膜作为光伏组件25年寿命保护用膜。

       本文从全球氟膜产业发展、氟膜加工工艺以及氟膜耐候原理等多个方面对氟膜，尤其是国产PVDF薄膜进行了详细研究。本文第一次全方位为光伏行业解读了氟膜行业，以及关于氟膜的各种观点背后的故事；从行业发展与氟膜技术的视角阐释了国产PVDF薄膜的发展现状与趋势，从而推动国产PVDF薄膜为平价上网做出贡献。
