JINERY Analyzed the Development of Distributed Photovoltaic: The Key is High-efficiency Photovoltaic Module
On April 18, 2018, the Second Distributed Photovoltaic Carnival jointly sponsored by China Photovoltaic Industry Association and PVMEN was held in Hangzhou, Zhejiang Province. QIAO Kai, deputy general manager of JINERY, the leading photovoltaic module manufacturer in Shanxi, was invited to deliver a keynote speech on Distributed Photovoltaic High-efficiency Module Solution.
In 2017, the accumulative capacity of photovoltaic power generation in China reached 130 GW. The photovoltaic capacity has ranked the first in the world for 3 consecutive years, accounting for 32.4% of the global photovoltaic capacity, among which the distributed photovoltaic capacity is more than 19GW, with a staggering year-on-year growth of 360%. And the recently formulated national policies are more promising to inject strong kinetic energy for the accelerated development of the distributed photovoltaic industry. According to relevant policies, the National Energy Administration will focus on choosing the municipal (county-level) regions and economic development zones, industrial parks and new urbanization areas with good development conditions including good distributed renewable energy resources and sites, great power demands, excellent grid access conditions and available nearby consumption as the pilot areas of distributed transactions, which will be officially launched before July 1, 2018.
QIAO Kai pointed out, “Over the past year, China’s distributed photovoltaic power generation has really entered the “fast track” of development. However, in the face of higher-than-expected growth of distributed photovoltaic in China, we need to think more about how to further promote the sustainable development of distributed photovoltaic and how to accelerate the realization of grid parity.” The high-efficiency module is the key to reducing the LCOE and finally achieving photovoltaic grid parity.”
Taking the 600m2 industrial and commercial roofs in east China as an example and setting polycrystalline 270W modules as the benchmark, the multi-crystal 280W and mono crystal PERC310W modules can be used to increase the power generation capacity of photovoltaic power station by 4% and 12% respectively in the whole life cycle (25 years); while HJT modules can extend the life cycle of a power station to 30 years andthe HJT 310W module can increase the life-cycle power generation of the power station by 46% and increase it to 59% by adding a reflective cloth.
At present, JINERY has conducted successful layout of three cutting-edge technologies including high-efficiency polycrystalline, high-efficiency mono crystal PERC and ultra-high efficiency heterojunction. According to QIAO Kai, under the conditions of 85℃ and 85% relative humidity, the PID of JINERY’s high-efficiency polycrystalline modules with gallium doped silicon is lower than 1%, which goes ahead of the industry average level.JINERY has achieved the mass production of 280W modules in the fourth quarter of 2017. Moreover, JINERY’s mono crystal PERC module adopts the leading electronic deposition technology, thus realizing the mass production of 310W modules.
QIAO Kai said, “In our view, grid parity can recently be realized in an accelerated manner. The ultra-high efficiency heterojunction technology is the most potential one because the efficiency of photovoltaic module has been improved obviously and this technology has realized mass production in China, thus creating great potential for cost reduction in recent 2 to 3 years.”
Compared with ultra-high efficiency technologies such as N-PERT and IBC, heterojunction technology (HJT) has many advantages including simple technological processes, no light degradation, no electric potential decay and low temperature coefficient, etc. At present, the average mass production efficiency of JINERY’s ultra-high efficiency heterojunction cell has reached 23.27% and the front side power output of HJT60 bifacial module has reached 332.6W.
Furthermore, the HJT mono crystal bifacial photovoltaic module innovatively developed by JINERY has successfully passed the IEC new standard test of TÜV Rheinland, thus becoming China’s first photovoltaic enterprise which has acquired the new standard certification.
QIAO Kai said, “Looking into the future, HJT with multiple advantages will not only be widely used in distributed, front-runner and other scenarios, but also will become one of the mainstream technologies for future development of photovoltaic industry and drive the industry to accelerate the realization of grid parity .”
