Longi says its hybrid passivated back contact (HPBC) 2.0 dual-glass modules have been installed for the first time in a distributed generation project. The 2.2 MW solar power plant in northeastern China is now commercially operational.
A 2.2 MW solar power plant with Long‘s HPBC 2.0 double-glazed PV modules are connected to the electricity grid in Yichun, Heilongjiang Province, China.
The array of Longis 630W HPBC 2.0 modulesis the first HPBC 2.0 distributed solar power plant to enter commercial operation.
The facility is located in the Longfei Wood Products Factory in Yichun, an area integral to China’s wood industry, and is expected to generate 3.2 million kWh per year for the factory. It was built as a ground-mounted installation, which Longi says will provide 25% more energy generation than a flat-roof installation.
The company said the use of its HPBC 2.0 modules will help the Longfei plant generate an additional 111,000 kWh annually compared to a year earlier. tunnel oxide passivated contact (TOPCon) PV installation with the same capacity, which represents a power gain of 3.56%. It added that the modules have an increased installed capacity of 5% compared to TOPCon modules over the same area, delivering an 8.56% gain in power generation.
The Chinese manufacturer launched the HPBC 2.0 range earlier this year, after unveiling the HPBC 1.0 technology in November 2022.
The company claims that HPBC 2.0 modules outperform TOPCon modules in resistance to UV, moist heat and thermal cycling. They also have a temperature coefficient of -0.26% per degree Celsius, an improvement of 0.03% per degree Celsius over TOPCon. These improvements ensure durability and reliable performance, even in Yichun, where winter temperatures can drop to -30 C.
“The establishment of the first HPBC 2.0 PV power plant not only supports Yichun’s transition from a wood-based economy to an ecological economy, but also signifies the nationwide potential for HPBC 2.0 distributed PV power plants to take root and flourish” , according to a statement from Longi. say.
In October, Longi’s HPBC 2.0 module set a new world record for crystalline silicon solar panel efficiency. 25.4%.
