The higher efficiency and lower cost are the main directions for R&D of photovoltaic modules. Some superposition technologies that can be used to increase the power of components are emerging: in terms of new battery technology, there are mainly PERC, N-type double-sided, double-sided passivation, etc.; and component technology, including MBB multi-barrier, half-sheet, shingle, and double-sided Glass and so on. The PERC technology is considered by the industry as the mainstream photovoltaic cell technology in the next three to five years.

The data shows that in 2017, PERC batteries accounted for more than 30 GW of the world's 125 GW of photovoltaic cell capacity, which was a doubling increase over the same period of last year. 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 continuously launched new PERC products and continued to increase the power of components and power generation. The company's "Hi-MO3" launched this year has a positive power of 320W.

Another domestic leading component of the GCL integration has also released four 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 the “Hi-MO3” of Longji Group, they use different component packaging technologies, but their purpose is precisely to increase the power of the components.

Oriental Sunrise (300118.SH) and Jinko Energy (JKS.N) unwillingly introduced new products with higher power components. Like the Longji Group, East Risen launched nine new products with "half-chip" and "PERC" as the core, including 60 laminated single-crystal PERC modules, half-chip polycrystalline silicon modules, half-chip single-crystal PERC modules, and 72 chips. Double-sided single-crystal PERC components and other products, the power of these products reached 335W, 360W, 390W and 420W.

Kyocera, a veteran component leading company, debuted the Cheetah 410W ultra-high-efficiency component during the SNEC exhibition. This well-known component manufacturer with module shipments of 9.8 GW last year also pulled the mainstream power supply of the components up to 400W.
