China's photovoltaic in rapid growth, since the implementation of PV "leader" program，there are more than 60 cities planned PV "leader" program, approved in 2017 "leader" project total size of more than 800GW, installed capacity is still rising , how to be the “leader” till the end in the PV long-distance running? The experts discussed the above issues in the October 24 at the "lead + long-distance running" photovoltaic hotspot seminar.

Early this year, the Green Card was introduced. When talking about the development prospects of the Green Card, the national response to climate change strategy research and international cooperation center, the original director of Li Junfeng said, "before 2020, China's PV to subsidize the main, green card supplement, 2020-2025 gradually transition to green Evidence and subsidies both, after 2025, with the increase of people’s awareness on the photovoltaic and environment, slowly transit to the green card-based. PV is the policy-driven industry, subsidies should be an orderly exit, rather than cliff-type exit, no matter “Leader”, or Long Run, no policy support is no way to do a good job.

The goal of parity Internet access is closely related to the service life of the power plant for 25 years. The longer the service life of the power station, the lower the cost of electricity.

China pv industry association secretary-general Wang Bohua points out, "if the present results is a" lead ", then improve the level of photovoltaic products and the quality of the photovoltaic power station, to ensure the long-term effective running of the photovoltaic power station is a real running process, this process is the main points of the photovoltaic products must attach great importance to the quality and reliability issues. How to guarantee the safe and effective operation of the project in different environments for 25 years is a common task facing manufacturers, design units and developers of pv products.

We should pay more attention to how to realize the photovoltaic power station whole life period of 25 years operation, high efficiency and reliable and longer service life and less efficiency attenuation, finally realizes the KWH cost reduce." China's renewable energy association principle matter feldspar atlas also feel the same way, only more pay attention to the quality and reliability of pv products, can help system capacity increasing, final photovoltaic parity on the Internet, maximize investment returns.

Dupont photovoltaic solutions for global Wang Wei, general manager of the truth, "in addition to the focus on system efficiency and system cost, more need to pay attention to the whole life of the power generation, this is 25 years reliability of pv systems. If you don't have 25 years of effective service life, then the value of the affordable Internet access may not be real or even misleading.

This year, China's photovoltaic industry has developed rapidly, and the "frontrunner" program has played an important role in guiding the direction of technological innovation of enterprises. This year, the third batch of pv "leaders" project, barriers to entry are greatly improved, the technology is "leading" base adopts silicon battery components and single crystal silicon cell component of photoelectric conversion efficiency, clear should be above 18% and 18.9% respectively.Shi Dinghuan pointed out: "to the development of photovoltaic technology innovation, model innovation and market innovation, including product whole life cycle of the impact of the environment, especially the deal with the problem of battery, from now on, to form the correct technical route, put recycling mechanism in the long-term development planning."

"Now called 'leading + long distance, is actually the technical innovation and quality assurance system, especially in the photovoltaic power station system design industry, technological innovation is actually a system integration concept, rather than simple packing of the products." "Said hu bing, vice President of Sungrow.
