Chinese solar module manufacturers are ramping to more than 750 GW of modules in 2024. This will likely be over 50% annual development over the 499 GW they delivered in 2023, in line with the China Photovoltaic Trade Affiliation (CPIA). China photo voltaic manufacturing trade ought to produce 820 GW of photo voltaic cells, up from the 545 GW in 2023. Silicon wafer output can be anticipated to exceed 935 GW this 12 months contemplating the enlargement plans of main firms within the area. Final 12 months, the nation rolled out near 622 GW, having gone up 67.5% YoY (see China’s Photo voltaic PV Output In 2023 Exceeded RMB 1.7 Trillion).

After delivering 1.43 million tons of polysilicon final 12 months with a 67% annual enhance, China is over 2.1 million tons this 12 months, in line with the CPIA that makes this forecast in its not too long ago launched China Photovoltaic Trade Improvement Roadmap (2023-2024).

China’s photo voltaic trade employed 3.5 million individuals in 2022 and this may very well be 5-6 million by the top of 2025.

For 2024, the affiliation forecasts China to put in as much as 220 GW AC new PV additions with land constraints and grid capability as the main challenges, after rising to 216.30 GW AC in 2023.

The present funding price of operationalizing a ten,000-ton trichlorosilane polysilicon manufacturing line is RMB 90 million/thousand tons (USD12.4 million per thousand tons). Anticipating technological enhancements, the funding/thousand tons will drop to RMB 80 million by 2030 (USD11 million per thousand tons).

Even in the case of silicon wafer thickness, the thinner the higher. The typical thickness of polysilicon wafers in 2023 was 170 μm. Whereas the CPIA doesn’t see any change to this worth this 12 months, it believes it could possibly change within the later years.

Wafer Sizes

There are numerous wafer sizes for photo voltaic cells available in the market at this time. The the share of 182 mm sq. wafers is 47.7%, whereas that of rectangular derivates of M10 format resembling 182mm x 183.75mm, 182mm x 185.3 mm, that are termed as micro-rectangular by CPIA (utilizing machine language translation), is 20.3%, however these might part out of the market in 2028.

The market share of 210 mm sq. wafers and rectangular wafers in 2023 was 20% and 10%, respectively. The latter most certainly refers back to the half lower wafers which are thus far used solely in HJT processing. Going ahead, these might develop into the longer term mainstream measurement, however these will nonetheless want steady verification by the market.

The TOPCon n-type silicon wafer merchandise for photo voltaic cells and heterojunction (HJT) cells have robust motivation to cut back thickness. The typical thickness of n-type silicon wafers utilized in TOPCon cells is 125 μm, and the thickness of silicon wafers utilized in heterojunction cells is about 120μm, which is a lower of 15μm and 5μm respectively in contrast with 2022.

Effectivity

In 2023, the common mass manufacturing photo voltaic cell effectivity of PERC cells reached 23.4%, 25% for TOPCon and 25.2% for HJT. By 2025, the CPIA forecasts the identical to extend to 23.7%, 25.7% and 26.2%, respectively. It doesn’t see any main breakthroughs going ahead since its steering for 2028 for these cell applied sciences is a most of 24%, 26.5% and 26.8%, respectively. For HJT effectivity, it elements in half cells of 182 mm and 210 mm codecs, which has developed because the cutting-edge for HJT.

Inverters

Amongst inverters, string inverters accounted for 80% market share final 12 months whereas central inverters claimed the remaining share. The affiliation foresees nice uncertainty available in the market shares of several types of inverters as adjustments happen in utility eventualities and expertise evolves.
