Recently, BYD said in an institutional survey that BYD has a professional solar energy technology research and development team, increasing investment in research and development, and establishing a photovoltaic technology research Institute to achieve the goal of reducing costs and increasing efficiency. After repeated experiments in the laboratory, BYD's solar energy technology research and development team strives to break through the previous test records in terms of cell efficiency and module efficiency, and further enhance the cost advantage of integration through the thinning of silicon wafers, the updating of silver paste technology and the iteration of film technology. With the continuous iteration and updating of crystalline silicon photovoltaic technology, the transformation from PERC battery technology to N-type TOPCon and HJT battery technology has been realized, and perovskite battery technology has been positively laid out to promote the conversion efficiency of batteries and stimulate the vitality of technological innovation.
BYD began to lay out photovoltaic in 2008, and the semi-annual report of 2023 shows that photovoltaic business, as one of the important layouts of BYD Group in the field of clean energy, has the whole industrial chain layout of silicon wafers, batteries, photovoltaic modules and photovoltaic system applications, and opens up all links of energy from absorption, storage to application. The Group will actively lay out new technologies and promote the continuous upgrading of products.
Data show that BYD began to lay out photovoltaic in 2008, and the semi-annual report of 2023 shows that as one of the important layouts of BYD Group in the field of clean energy, photovoltaic business has the whole industrial chain layout of silicon wafers, batteries, photovoltaic modules and photovoltaic system applications, which opens up all links of energy from absorption, storage to application. The Group will actively lay out new technologies and promote the continuous upgrading of products. The layout of
new energy vehicles in the photovoltaic industry is not uncommon. BYD is the leader in this field, and since then, General Motors, Tesla, Geely and others have extended their business to the photovoltaic field. In July
2011, GM announced a $7.5 million investment in Sunlogics PLC, a supplier specializing in the development and installation of solar equipment. A year later, the company announced that it would cooperate with China Building Materials International Engineering Group to jointly develop building photovoltaic integration projects.
In 2016, Tesla acquired SolarCity, hoping to provide users with their own solar solutions. Subsequently, Tesla has been increasing its investment in rooftop photovoltaics. In addition, Tesla has introduced solar inverters to make up for its shortcomings in the field of solar energy. On February 5,
2021, Geely Automobile established Zhejiang Haohan Energy Technology Co., Ltd. with a registered capital of RMB 30 million. According to the public information of Tian Eye Check, its business scope includes sales of photovoltaic equipment and components, solar power generation technology services, etc.
In addition, Geely Group is also actively planning the photovoltaic polysilicon track. In December
2021, Geely Silicon Valley (Gucheng) Technology Co., Ltd. was established to specialize in the research, development, production and sales of 6N solar grade polysilicon. On May 21, 2022, Geely Silicon Valley Polysilicon Project was officially put into operation in Gucheng County, Xiangyang City, marking that Geely Silicon Valley solar-grade polysilicon has entered the stage of mass production. With a total investment of 22.8 billion yuan, the project plans to "promote the upstream and downstream layout of the industrial chain of silicon ore, industrial silicon, polycrystalline silicon, single crystal pulling, slicing, cells, components and photovoltaic power generation ". Geely Technology Group plans to produce 200,000 tons of polysilicon annually in 2025 and 500,000 tons in 2030, becoming one of the leading enterprises in the industry.
This year, in order to enter the photovoltaic industry, Ideal Automobile set up a company crazily, and set up 87 photovoltaic enterprises in less than one year and two months. These 87 enterprises cover 22 provinces and cities, and their business scope includes sales of photovoltaic equipment and components, manufacturing of photovoltaic equipment and components, and technical services for solar power generation. This "feat" shocked the industry for a long time. On August 30,
2023, Weilai Automobile joined hands with Goodway to invest in Hefei Baobi New Energy, a photovoltaic enterprise, and extended its business to the photovoltaic field with a low profile.
In addition, on October 20, BYD Solar launched a household photovoltaic solution to enter the household photovoltaic market.
