Module price competition intensifies as capacity ramps continue
Polysilicon Polysilicon prices for mono-Si wafer stayed flat this week. The trading price of some producers increased marginally by less than RMB 1/kg, sitting at around RMB 58-60/kg and RMB 59/kg for average. Overall, polysilicon manufacturers are attempting to raise price for July orders, but they are biding their time as mono-Si wafer prices are expected to decline and some manufacturers are still filling June orders. At present, some downstream manufacturers are conservative about price increase. Moreover, inventories overall are maintained at a certain level and supply will become stable as polysilicon producers that are under maintenance program are gradually [...]
210mm high power modules bring down LCOE further
Following Trina Solar’s launch of modules featuring 500Wp+, several Chinese manufacturers also unveiled high-power modules based on different wafer sizes, accelerating the transition to grid parity. With cell efficiency hitting bottleneck, utilizing larger wafers to drive LCOE down and efficiency up has become a trending topic. While solar costs continue to drop, global end-user demand has room for growth. Capacities in the wafer, cell, and module segments are sufficient to fulfil demand for products based on 180-210mm format. In response to the shift of wafer sizes, manufacturers are gearing up for adopting 210mm format in their new capacities, and this [...]
Identification and prevention of mirco-cracks in PV modules
Photovoltaic modules micro-crack, hot spot, PID effect are three important factors affecting the performance of photovoltaic modules. Today, we will take you to understand the cause of the photovoltaic modules micro-crack, how to identify and prevention methods. I. Formation and classification of cracks in photovoltaic modules Micro-cracking is a common defect of photovoltaic modules, namely, some invisible micro-cracks.Due to its own crystal structure, crystalline silicon solar modules are prone to fracture.In the production process of crystal silicon module, many links may cause the cell sheet to crack.The root causes of fissure: External force: The solar cells will be subjected to external force [...]
Why the wafer is getting more bigger and bigger?
With the development of technology, the size of monocrystalline silicon wafer is increasing. Before 2012, the size of monocrystalline silicon wafers was mainly divided into two types: 156mm margin and 125mm margin. At the end of 2013, longi, Zhonghuan and other five major manufacturers took the lead in unifying the silicon wafer size with a standard of 156.75mm At the beginning of 2020, Longi, Zhonghuan introduced large silicon wafers with the sizes of 166mm ,182mm and 210mm respectively. The reason is that the increasing size of silicon wafers can bring many aspects of cost reduction and efficiency increase for all downstream links. The [...]
