On September 25, the official WeChat of Longji Green Energy announced the release of the world's first BIPV product with BC batteries, Longding 4.0 . In the article, Longji once again showed the market its firm determination to choose the BC route.
The original text is as follows:
On September 23, Longji Green Energy and Sent Co., Ltd. jointly released a new generation of building integrated photovoltaic (BIPV) product , Longding 4.0, in Beijing .
Longding 4.0 is the world's first BIPV product with BC batteries, and it is also a safer, more efficient and more reliable BIPV product jointly released by Longji Green Energy and Sent.
For a long time, buildings have been the "big consumer" of electricity in China, accounting for one third of the total electricity consumption in China, and their carbon emissions also account for more than one third of China's carbon emissions. "BIPV, as an effective way to reduce building energy consumption in China, vigorously develops low-carbon and zero-carbon buildings, which has important practical significance for energy conservation, emission reduction and environmental protection." "Longding 4.0 is the world's first BIPV product with BC batteries, and technological innovation has also brought about a significant improvement in product performance," said Chen Pengfei, president of Longji Green Energy China Government and Enterprise Regional Department.
BC batteries will gradually become the absolute mainstream of crystalline silicon batteries in the next 5 to 6 years. Gao Wei, vice president of Sent Co., Ltd., said: The Longding 4.0 product launched this time has been upgraded from PERC battery to HPBC battery. Compared with Longding 3.0 product, Longding 4.0 product cancels the grid line, which not only achieves high efficiency, but also takes into account the high face value, which is more in line with the application of architectural scenes. In the same roof, the comprehensive power generation of the roof-lifting 4.0 product is increased by more than 8%. Lv yuan, president
of Longji Green Energy Products and Solutions Center, said, BC battery technology is facing difficulties in research and development, mass production and cost reduction, but it also has the advantages of high conversion rate, high power generation rate, high weak light rate and high customer income. The reason why Longji Green Energy chose BC technology is that Longji Green Energy has always adhered to the first principle of long-term doctrine and has been trying to do difficult and correct things.
As a power generation equipment, BIPV should have the basic requirements of high efficiency, safety and reliability. The newly upgraded Longding 4.0 product, equipped with HPBC battery technology, can achieve a 30-year power generation efficiency of more than 86.9% of efficient power conversion capacity, far exceeding similar products; the conversion efficiency has reached a new high of 22.6%, and the output power has reached 580 W; Fully extend the power generation time, constantly break the efficiency limit, and provide customers with safe, stable and reliable income guarantee for 25 years.
In addition, the operation and maintenance team of Longji Green Energy and Sent Co., Ltd. has also developed and established the world's first intelligent roof and photovoltaic monitoring and operation and maintenance system with independent intellectual property rights, which integrates the two core systems of roof monitoring and photovoltaic operation and maintenance with the distribution of instructions, data analysis and data acquisition; Ensure the stability and reliability of the roof system, effectively detect and manage the operation of the power station, and ensure the stable operation of the building + photovoltaic "integrated system".
