With the continuous development of solar energy industry, photovoltaic modules have been widely used in photovoltaic power stations. Thanks to the rapid development of relevant technologies in the past decade, the affordable Internet access of photovoltaic power stations is also approaching. However, it is not a smooth journey for photovoltaic power station to connect to the Internet at a fair price. Some manufacturers even gain excess profits at the cost of product quality. As wang bohua, secretary-general of China photovoltaic association, hopes: "photovoltaic industry has become as beautiful as China's high-speed railway business card, let the world sit up and take notice, I hope the whole industry can cherish this hard-won industry, the photovoltaic industry will be able to develop well and healthily.

In photovoltaic modules, photovoltaic backboard is a kind of protective material, which mainly plays the role of supporting components, isolating water vapor and oxygen, and has to withstand the test of very complex and different outdoor environments around the world. Therefore, the reliability of its materials is crucial. MPPT charger controller
The thickness is directly related to the properties of the film and has a significant effect on the aging properties. When choosing thinner fluorine film protective layer, we should choose the fluorine film with reliable thickness as protective layer according to the environmental complexity of different areas. 12V 24V solar charge controller
In complex and different environments, the protective film used on the back of photovoltaic modules will have a tendency of thinning under the comprehensive effect. From the point of view of thinning speed and various performances, it is suggested to ensure the thickness of PVDF film on the back of photovoltaic modules at 25um or even more than 30um in severe environment, so as to ensure the long-term operation of photovoltaic modules more reliably.

With the development of the photovoltaic industry in recent years, the trend of localization of fluorine film for photovoltaic module backboard has become more and more obvious. Some leading domestic component manufacturers have started to input domestic PVDF film into qualified supplier BOM. Photovoltaic market changes rapidly, the only constant is the industry colleagues to reduce the cost of unremitting efforts. Maintaining and increasing the thickness of fluorine film is a favorable guarantee to ensure the long-term use of photovoltaic modules and give full play to their power generation efficiency. However, blindly reducing the thickness of fluorine film protection layer is bound to lead to unstable product performance, thus affecting the long-term operation of photovoltaic modules.
