Photovoltaic industry to advanced production capacity for upgrading
Photovoltaic industry continues to maintain high growth. The National Energy Board recently released data showing that in the first half of the year, the country's new PV grid-connected 78.42 million kilowatts, an increase of 154% year-on-year, of which centralized PV power generation 37.46 million kilowatts, an increase of 234% year-on-year, distributed photovoltaic power generation 40.96 million kilowatts, an increase of 108% year-on-year. Not only effectively play the role of stabilizing investment and promoting growth, but also inject momentum and vitality for high-quality economic and social development.
Rapid growth of photovoltaic installations
In the first half of the year, photovoltaic power generation new installations and last year's annual data is about the same, accounting for 56% of the total new power supply installed. As of the end of June, photovoltaic cumulative installed capacity of about 470 million kilowatts, is China's installed capacity of the second largest power supply, second only to coal power.
Behind the rapid growth of photovoltaic installed capacity, there is a strong manufacturing support. Ministry of Industry and Information Technology recently released data showing that in the first half of the year, China's photovoltaic industry in general maintains a stable and positive development trend, the main links in the industrial chain production have achieved high growth. According to the photovoltaic industry standardized announcement of enterprise information and industry associations, the national polycrystalline silicon, silicon wafers, batteries, components production reached a new high, year-on-year growth of more than 65%. The total export of PV products reached US$28.92 billion, up 11.6% year-on-year.
Accelerating technology upgrades
Against the background of overcapacity, high-efficiency advanced PV cells are in short supply.
The advent of the era of comprehensive grid parity requires PV power generation to continuously improve power generation efficiency and reduce power generation cost without relying on subsidy policies, which poses a challenge to the technological innovation of PV enterprises. The current photoelectric conversion efficiency of P-type batteries has gradually approached its theoretical upper limit, battery technology is facing a new inflection point, technology iteration needs strong. The next generation of battery technology is mainly focused on N-type battery technology represented by TOPCon, ABC and HJT.
From the PV industry's development history over the past 20 years, due to the rapid iteration of PV technology and products, the PV industry's built and planned production capacity under construction has long been in a state of excess far exceeding the market demand, but the advanced production capacity often appears to be insufficient. To focus on promoting the innovative development of PV industry, in-depth implementation of photovoltaic manufacturing industry norms and conditions and intelligent photovoltaic industry innovation and development action plan, to carry out a new batch of photovoltaic industry norms and announcements to declare and intelligent photovoltaic pilot demonstration activities, and to promote the photovoltaic industry technology to continuously accelerate the upgrade.
