6 FAQs about [Photovoltaic inverter chips are controlled by foreign countries]

What is the global solar PV inverter market like in 2023?

Global solar PV inverter* shipments grew by 56% in 2023 to 536 GWac, with China accounting for half of all shipments as the country’s solar demand doubled in 2023, according to the latest analysis by Wood Mackenzie. The top 10 PV inverter vendors, led by Chinese giants Huawei and Sungrow, controlled 81% of the global market.

Which countries install the most PV inverter in the world?

At a country level, China, the United States and India were the top countries, collectively accounting for approximately 70% of global PV inverter installations in 2018.

Will a global PV supply chain expand outside of China?

The high level of geographical concentration in the global PV supply chain has led the European Union, India and the United States to introduce policy incentives to support domestic PV production. This could result in an unprecedented expansion of PV manufacturing outside of China in the next five years.

How has global solar PV manufacturing capacity changed over the last decade?

Global solar PV manufacturing capacity has increasingly moved from Europe, Japan and the United States to China over the last decade. China has invested over USD 50 billion in new PV supply capacity – ten times more than Europe − and created more than 300 000 manufacturing jobs across the solar PV value chain since 2011.

Who owns the global PV inverter market?

The top 10 PV inverter vendors, led by Chinese giants Huawei and Sungrow, controlled 81% of the global market. Huawei and Sungrow alone captured over 50% of the global share, thanks largely to their popular utility-scale inverters, reports the market analyst.

Which countries have the lowest solar PV module manufacturing costs?

Today, China and ASEAN countries (Viet Nam, Thailand and Malaysia) have the lowest solar PV module manufacturing costs for all segments of the supply chain. Economies of scale, supply chain integration, relatively low energy costs and labour productivity make China the most competitive solar module manufacturer worldwide.
