At the end of 2023, global PV manufacturing capacity was between 650 and 750 GW. 30%-40% of polysilicon, cell, and module manufacturing capacity came online in 2023. In 2023, global PV production was between 400 and 500 GW. While non-Chinese manufacturing has grown, most new capacity continues to come from China.

Based on new information, annual and cumulative solar values now assume that China’s National Energy Administration (NEA) reports distributed PV in direct current terms and utility -scale PV in alternating current terms. Sources: China NEA (1/18/23); IEA, National Survey Report of PV Power Applications in China, 2021.

The country that establishes the international standards for PV inverters will have a first-mover advantage, providing a window of opportunity to restore U.S. competitiveness in PV inverter design and manufacturing. The United States would benefit from being the first to commercialize perovskite PV technology. However, it would be unprecedented .

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.

Specific to the solar industry, the DOE’s Solar Energy Technologies Office (SETO) aims to increase new U.S. photovoltaic (PV) manufacturing capacity by 1 GW per year and installed solar hardware to contain at least 40 percent domestic value. The United States has lost roughly 80 percent of its global market share in the production of .

6 FAQs about [New policy for photovoltaic inverters]

What are India's favourable solar PV manufacturing policies?

Favourable solar PV manufacturing policies in India and the United States have spurred multiple new project announcements. In the first phase of India’s PLI programme, almost 9 GW of integrated manufacturing capacity were contracted, and in the second phase the government is expecting to subsidise another 65 GW.

Why are solar PV modules and inverters falling in price?

Despite the unprecedented demand growth in recent years, solar PV modules and inverters have fallen in price, benefiting project developers and disadvantaging manufacturers, who have struggled to sustain margins.

Are control strategies for photovoltaic (PV) Grid-Connected inverters accurate?

However, these methods may require accurate modelling and may have higher implementation complexity. Emerging and future trends in control strategies for photovoltaic (PV) grid-connected inverters are driven by the need for increased efficiency, grid integration, flexibility, and sustainability.

How is the solar PV industry changing?

The solar PV industry is changing rapidly, with innovations occurring along the entire value chain. In recent years, a major driver for innovation has been the push for higher efficiency (Green, 2019).

Can grid-connected PV inverters improve utility grid stability?

Grid-connected PV inverters have traditionally been thought as active power sources with an emphasis on maximizing power extraction from the PV modules. While maximizing power transfer remains a top priority, utility grid stability is now widely acknowledged to benefit from several auxiliary services that grid-connected PV inverters may offer.

How efficient are PV inverters with sic devices?

In the literature, efficiencies of 99 % for PV inverters with SiC devices are reported, even if the higher cost is actually a limit for practical industrial use . In Table 2 a comparison of selected topologies, each one representing each described families is carried out.
