Guided by local governments, which excessively pursued for local GDP growth, the polycrystalline silicon and solar PV cell manufacturers spared no efforts to expand production, while many enterprises in other industries also entered in this field. Then, serious overcapacity began.
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.
PV manufacturing capacity is projected to more than double by 2024, led by China, but oversupply is also anticipated, according to the International Energy Agency (IEA). Global solar PV manufacturing capacity is set to nearly double next year, reaching almost 1 TW, according to the IEA.
Global capacity for manufacturing wafers and cells, which are key solar PV elements, and for assembling them into solar panels (also known as modules), exceeded demand by at least 100% at the end of 2021. By contrast, production of polysilicon, the key material for solar PV, is currently a bottleneck in an otherwise oversupplied supply chain.
The overcapacity in China's PV industry here refers to overcapacity of PV products such as silicon, polycrystalline silicon, solar cells and PV modules. Impacted by the US Financial Crisis and the European Debt Crisis, the market demand for PV products has been shrinking, resulting in more serious overcapacity of the industry.
In 2022, global PV manufacturing capacity increased by more than 70% to nearly 450 GW, with China accounting for more than 95% of new additions across the supply chain. In 2023 and 2024, global PV manufacturing capacity is expected to double, with China again accounting for more than 90% of the increase.

Rather than curtail supply whenever power demand falls below that supplied from the renewable capacity, it becomes more practical to use any excess capacity to desalinate seawater (where potable water is not available) and use it to produce H 2. Similarly, it may also be the case that a particular PV plant is ideally located in terms of annual ...
Overcapacity in China''s photovoltaic industry refers to overcapacity of photovoltaic products such as silicon, polysilicon, solar cells, and photovoltaic modules (Wang et al., 2014).
This expansion has led to massive production capacities that now exceed current market demands. Falling Prices: The cost of solar panels has plummeted, making solar energy more accessible but also leading to an oversaturated market. The resulting surplus has made it increasingly challenging for manufacturers to maintain sustainable operations.
When production levels significantly exceeded installations in 2022 and the first half of 2023, inventories built up throughout the supply chain, leading to an inevitable price crash.
The fundamental philosophy of improved PV cells is light trapping, wherein the surface of the cell absorbs incoming light in a semiconductor, improving absorption over several passes due to the layered surface structure of silica-based PV cells, reflecting sunlight from the silicon layer to the cell surfaces [36].
