电子发烧友网报道（文/李诚）据统计，截至2021年三季度，我国光伏发电机累计装机量达275GW，同比增长25%，累计新增装机量 22GW，同比增长 45%。并在十四五规划中明确指出，到2025年我国光伏发电系统装机量有望突破400GW大关。
从行业发展角度与能源利用率来看，碳化硅光伏逆变器有望替代传统的硅基光伏逆变器，并成为行业发展的重点。据了解，使用碳化硅功率器件的光伏逆变器在系统转换效率方面能够很好的保持在96%以上，甚至可以达到99%，在能量损耗以及设备使用寿命方面也得到了不同程度的优化。根据 CASA 预测，到2048年在光伏逆变器中，高效、低损耗的碳化硅功率器件占比有望达到85%以上。
According to statistics, by the third quarter of 2021, the cumulative installed capacity of photovoltaic generators in China reached 275GW, a year-on-year growth of 25%, and the cumulative new installed capacity of 22GW, a year-on-year growth of 45%. In the 14th Five-Year plan, it is clearly pointed out that the installation of photovoltaic power system in China is expected
to exceed 400GW by 2025.
Now the photovoltaic industry has entered a rapid growth stage, and has brought tens of billions of market size. Thanks
to the development of the photovoltaic industry, the photovoltaic inverter, whose construction cost is nearly 20% in the photovoltaic energy storage system, has also ushered in a new opportunity for development, attracting many players to enter the
fierce competition in the circuit of photovoltaic energy storage inverter.
From the perspective of industry development and energy utilization, silicon carbide photovoltaic inverter is expected to replace the traditional silicon based photovoltaic inverter, and become the focus of industry development. It is understood that the photovoltaic inverter using silicon carbide power devices in the system conversion efficiency can be
well maintained at more than 96%, and even can reach 99%, in terms of energy loss and equipment service life has also been optimized to different degrees. According
to CASA, the proportion of high efficiency and low loss silicon carbide power devices in PV inverters is expected to reach more than 85% by 2048.
So far, in the field of photovoltaic inverter Infineon, Fuji Electric, Mitsubishi Electric, Anson, Sun Power and other enterprises have carried out in-depth layout on the application of silicon carbide, and successfully developed mass production products.
