1. The main technical routes of solar modules include PERC, n-type TOPCon, HJT heterojunction and other technical genres, among which n-type TOPCon accounted for about 90% of last year's shipments;
2. The module is being larger. The current commercialized large modules are 660-670W, based on 72 pieces of 210 cells;
3. As far as cells are concerned, 166, 182, and 210 are the main models, of which 182 series is the mainstream of current applications. Generally, 560W is based on 144 half-cut (72 pieces) of 182 cells, and 460W is generally based on 72 cells of 166 cells, or 60 pcs of 182 cells;
4. The high-voltage PV system is transitioning from 1500V to 2000V ultra-high system voltage level;
5. New applications:
1) In recent years, the demand for offshore floating photovoltaic systems has been increasing. Sungrow has been deeply involved in the application of this field for many years. At present, it has a professional cross-border combination team and more than 200 large and small project cases;
2) BIPV seems to be still a hot spot in the industry, and is currently in the process of continuous improvement of industry standards.
