On April 25, 2023, the "2023 Distributed Photovoltaic Innovation Summit" sponsored by Polaris Solar Photovoltaic Network and jointly sponsored by Sunrise Oriental Holdings Co., Ltd. was officially held in Lianyungang, Jiangsu. At the meeting, Chen Tiejun, General Manager of Systems Engineering Research Institute of Yidao New Energy Technology (Quzhou) Co., Ltd., gave a keynote speech on "Green with one hand and safe with one hand, BIPV Photovoltaic Roof with one hand".

According to Chen Tiejun, there are currently three major pain points in the county's distributed photovoltaic and distributed photovoltaic markets: one is fire safety, and fire accidents frequently occur in distributed photovoltaics; the other is product life. Color steel tile roofs need to be replaced every 5-8 years. However, the service life of the photovoltaic module is 25 years, and the two do not match; the third is that it is difficult to clean, the inclination angle of the photovoltaic module is small, and after the water evaporates, the dust settles into stubborn stains, which makes cleaning difficult. Aiming at the above pain points, Yiyi Xinneng overcomes them one by one through the three major innovations of photovoltaic module-level rapid shutdown system, lightweight shingled photovoltaic modules, and self-draining steel frame modules. It is worth mentioning that Yidao Xinneng's photovoltaic module rapid shutdown system has independent intellectual property rights, breaking the foreign monopoly.

At the forum, Chen Tiejun introduced a new material BIPV roof. The roof realizes the integrated photovoltaic integration of customized color steel tiles and lightweight components, which greatly reduces the cost and improves the life of the roof; for the later installation of photovoltaics on the existing roof, a new energy adopts self-draining steel frame components and quick-installation fixtures to make rainwater It can be drained automatically and has an auxiliary cleaning device. Not only that, from the perspective of the EPC project general contracting business model, Yiyi is the first to propose a standard version of quick shutdown, which means that when doing roof projects, quick shutdown can be added to improve safety.

Finally, Chen Tiejun gave a detailed introduction on the overall business sector of Yidao Xinneng. As one of the earliest photovoltaic companies in the industry to deploy N-type technology, Yidao Xinneng continues to lead the development of N-type technology by virtue of its dedicated research and deep cultivation of N-type technology. N-type leader represents Song Dengyuan, Chief Technology Officer of Dao Xinneng.

Yiyi Research Institute mainly promotes photovoltaic system solutions for all scenarios and processes, which are divided into three sections: ecological photovoltaics, urban photovoltaics and offshore photovoltaics, with 18 specific application scenarios. About ecological photovoltaics, including mid-span dimming-type flexible support photovoltaic sand control scheme, medium-span large-angle flexible support mountain photovoltaic scheme, medium-span flexible high-stent river photovoltaic scheme, medium-span flexible high-stent animal husbandry complementary scheme, large Complementary solutions for agriculture and photovoltaics with flexible high-span support; for the urban photovoltaic sector, including light-weight module direct-attached photovoltaic roof solutions, mobile charging piles shared by zero-carbon service areas and urban parking lots, and integrated solar-storage-charge parking lots in zero-carbon service areas Scheme, wind-storage storage smart micro-grid zero-carbon factory scheme, etc.; Regarding the offshore photovoltaic sector, it includes offshore photovoltaic schemes for offshore photovoltaic pile-based anti-table flexible support offshore photovoltaic schemes, and offshore amphibious/inner lake floating photovoltaic schemes.
