The application advantages in the field of photoelectric energy storage are clear, and the permeability of silicon carbide devices is rapidly increasing.
Author:
Silicon devices have been widely used in photovoltaic, wind power and energy storage inverters. After more than 40 years of development, the conversion efficiency and power density are close to the theoretical limit. The cost of traditional inverters based on silicon-based devices accounts for about 10% of the system, but it is one of the main sources of system energy loss. Silicon carbide devices can be applied to wind power rectifiers, inverters and transformers, reducing energy loss and improving efficiency while reducing quality and cost by 25% and 50%, respectively. Energy storage industry chain development layout, silicon carbide market space further opened. With the gradual increase in the proportion of renewable resources with indirect and volatile characteristics such as photoelectric and wind power, the society has put forward higher requirements for energy stability. Energy storage has become the key to solve the problem of energy volatility and the matching of supply and demand of power system, and has great market potential. Silicon carbide energy storage inverter improves system efficiency by 3%, power density by 50%, and reduces the volume and cost of passive devices, it is widely used in the field of energy storage.

According to TrendForce forecasts, the new installed capacity of global energy storage will reach 29.6GWh in 2021 and 362GWh in 2025. According to IHS forecast, the global energy storage inverter will reach 12.7GWh in 2020, and the global energy storage inverter market size is expected to be 63GWh in 2018-2022. Demand Forecast: It is estimated that by 2025, the total new installed capacity of wind power, photovoltaic and energy storage in the world will increase to 687GWh, corresponding to the market size of power devices of about 25.5 billion yuan, the penetration rate of SiC power devices of 50%, and the demand for equivalent 6-inch wafers of 890000 chips. Assume that 6-inch silicon carbide wafer 5000 yuan/piece by 2025, corresponding to the silicon carbide wafer market space of 4.45 billion yuan.
