The higher the efficiency, the lower the cost is the main direction of research and development of photovoltaic modules. Some superposition technologies that can be used to increase the power of the components are emerging: In the new battery technology, there are mainly PERC, N-type double-sided, double-sided passivation, etc.; , Including MBB multi-gate, half-chip, shingle and double-glazed glass, etc. PERC technology is considered by the industry as the mainstream photovoltaic cell technology in the next three to five years.
Data show that in 2017, PERC batteries accounted for more than 30 GW of the world's 125 GW of photovoltaic cell capacity, and the year-over-year growth rate doubled. More optimistic people predict that by the end of this year, global PERC battery capacity will exceed 60 GW.
In the past two years, Longji has also launched new PERC products and continued to increase component power and power generation. The company’s 'Hi-MO3' launched this year has a positive power of 320W.
Another domestic leading component of the Group has also released 4 MBB 'super-efficient 300W+' series of new products, divided into single, double glass two series, and both contain multiple single crystal module products.
From the product name, it is not difficult to find that although the new products released by GCL are integrated with Longi’s 'Hi-MO3', different component packaging technologies are used, but the purpose is to increase the power of the components.
Oriental Sunrise (300118.SH) and Jinko Energy (JKS.N) unveiled the launch of new products with higher power. Like Longji, Oriental Sunrise launched the 'Half-chip' and 'PERC' as its core. 9 new products, including 60 laminated single-crystal PERC modules, half-chip polysilicon black silicon modules, half-sheet single-crystal PERC modules, and 72 double-sided single-crystal PERC modules. These products have a power of 335W, 360W, respectively. 390W and 420W.
The veteran component leader, JinkoSolar, debuted the 'Cheetah 410W ultra-high efficiency module' during the SNEC exhibition. The company’s well-known module manufacturer with 9.8 GW component shipments last year also boosted the mainstream power capacity of its components. To 400W or more.
