The recent "first Household Photovoltaic Development and Innovation Forum" mentioned that the inverter supply pressure caused by chip shortage may become a potential bottleneck in the industry chain. Household photovoltaic more than expected stack chip shortage, inverter companies may increase the price means to transmit part of the cost pressure.
Since the end of 2020, the global chip shortage has affected the production of many industries. The chip is also the core component of the inverter, of which semiconductor devices dominated by IGBT account for about 10% of the inverter cost. as raw materials account for more than 90% of the inverter cost, the price of upstream raw materials has risen sharply since the second half of last year with the gradual recovery of the global economy.
The rising price tide of the photovoltaic industry chain has been extended to the inverter side recently. It is reported that domestic photovoltaic inverter head enterprises Gu Dewei and Guriwatt have issued price adjustment instructions-- the prices of inverter products of the two companies have increased by 10%, 15%, and the adjustment dates are April 12 and 13, respectively. Jinlang Technology and Shangneng Electric have not been adjusted yet.
Last year, domestic inverter manufacturers went out to sea to accelerate, according to customs data, overseas inverter export data in the first two months of this year are still exuberant. The cumulative export value of RMB-denominated inverters was 4.503 billion yuan, an increase of 83.9% over the same period last year in 2020. According to expert opinion, the demand for inverter in 2021 is still optimistic, and it is optimistic that the rapid development of household photovoltaic and energy storage will lead to a high growth of inverter demand in the future.
Jiang Xinhao and Zhang Yuqi, researchers of China International Capital Corporation, said that domestic and overseas photovoltaic installations are expected to reach 60 and 110GW in 2021, with a total demand growth of 35% compared with the same period last year. In the long term, the rapid development of distributed household photovoltaic and energy storage systems is also expected to accelerate the rapid growth of inverter demand. The global market share of domestic head inverter enterprises is expected to continue to increase.
Specific to the investment target, Zhang Lei, an analyst at Shenwan Hongyuan, said that the technical tuyere of all kinds of inverters has arrived, and the integration of optical storage and intelligence are the two major technological trends in the industry in the future. Recommended to pay attention to the inverter link of the leading companies Sunshine Power supply, Jinlang Technology, Gu Dewei, it is recommended to pay attention to Shangneng Electric, Costa. Among them, Gu Dewei ranked among the top 10 inverter shipments in the world last year, the global shipments of three-phase / single-phase series inverters ranked sixth and fifth respectively, and the market share of household energy storage inverters was 15%, ranking first in the world.
