The 6 major trends of PV modules in 2018:
1, Single crystal + PERC is already basic equipment: Benefit from continuous supply chain expansion, PERC prices continue to decline, and LID problems can be solved through new processes and other reasons, PERC is already the basic mix of single crystal production, When stacking other technologies, the 60-cell wattage is at least 300W.
2. The polysilicon is basically matched with black silicon. Whether superimposed PERC technology is different from each other: In terms of the number of wattages of polycrystalline components exhibited at PV EXPO 2018, most polycrystalline cells are matched with black silicon and PERC. However, whether or not the actual production line is on the PERC is considered. In addition, only one polycrystalline double-sided component was exhibited at the GCL-SI booth at this time. The wattage is 295W.
3, multiple technical routes: N-type, double-sided, MBB, half-sliced, lamination and other five technical routes in this year's show have a good shooting rate, some of which can be superimposed on each other (such as N-type + two-sided), part Mutual exclusion (such as half-cut and lamination). Compared with the other four categories, MBB is mainly a technical superposition role.
4. Half-cell battery becomes standard: There are more than 20 manufacturers exhibiting half-chips in this exhibition, including most of the first-line players. The highest wattage of single-poly 60-cell is 325W and 300W respectively, which is obviously high. In general single-crystal PERC; plus technical bottlenecks have been broken, this year will enter the mass production phase.
5, Double-sided battery technology, N and PERC each account for half of the country: Double-sided components are expected to be the next new technology to enter mass production. At present, the industry adopts the “buy-in-the-front-to-backside” method. In this exhibition, The battery with double-sided power generation is subdivided by single-crystal PERC and n-PERT/HJT, and each has its own support. Some have further superimposed the MBB or half-chip manufacturing process.
6, The lamination package has a higher sound volume, of which SunPower is the most amazing: The SunPower, which holds the laminated patent, first introduced the lamination assembly on the PV EXPO 2018 with a wattage of 390W. Overall, the visibility of laminated laminations at this year's show is even greater. High, and with the battery technology can be basically unlimited, the industry can consider technology research and development and reserves.
