New figures provide clarity on solar module glut, ‘dumping’ prices


The statements made by some market participants about quantities of Chinese solar modules in EU warehouses, rock-bottom prices and suspected “dumping” practices are increasing and somehow diverging from each other.

A classification based on numbers may help us to understand the new reality of the rapidly growing global PV market, which is poised for further expansion this year.

Global production capacity in terms of GW, modules

2019: 118 GW or around 340 million modules
2023: 380 GW or about 844 million modules

EU market in GW, modules

2019: 16.7 GW, or around 48 million modules per year, 4 million modules per month
2023 (optimistic scenario): 80 GW or 178 million modules per year, 14.8 million modules per month

EU module inventory “normal” (two-month cycle)

2019: 2.8 GW, or around 8 million modules
2023: 13.3 GW, or around 30 million modules

Inventories in the double-digit gigawatt range in the European Union are the new “normal” in an ever-growing PV market. “Horror scenarios” of 120 GW in EU warehouses by the end of the year would mean 290 million modules in warehouses.

Inventory values of modules (base €0.15/W)

1 GW = €150 million ($161 million)
10 GW = €1.5 billion
120 GW = €18 billion

“Horror scenarios” of 120 GW in EU warehouses would therefore require almost €18 billion of “dead” capital. How will this be financed? The new “normal” requires capital.

Purchasing prices for large PV projects in Germany

2019/20: €0.16W to €0.19/W
September 2023: €0.15W to €0.17/W

Price reduction based on the PV learning curve

2019-23: €0.04/W to €0.06/W

After roughly looking at the photovoltaic learning curve, the expected price in 2023 would be between €0.10/W to €0.15/W.

Solar module costs according to a document published by the European Solar Manufacturing Council (ESMC) on Sept. 11

EU stock: €0.33/W
EU: €0.299/W
China: €0.254/W

Solar module costs (excluding margins) from an ESMC member (as of the end of 2022)

EU: €0.198/W
China: €0.169/W

Share of silicon produced in China from Xinjiang (estimates for 2023):

Around 30%

The 380 GW of new PV installations expected throughout the world in 2023 could be produced entirely without silicon from China's Xinjiang region.

Variable costs for polysilicon

Global average: $8.20/kg
Wacker (Germany): $18/kg

Success in climate protection

Modules in 2019-20 were mostly up to around 350 W and based on monocrystalline PERC technology. Currently, monofacial, monocrystalline PERC modules are slowly being phased out, with PV technologies such as TOPCon and heterojunction that are taking over the market for projects, with module outputs of up to 575 W.

Chinese module suppliers have grown rapidly since 2019 to supply this impressive global market. And the learning curve in production continued – the modules are much more efficient now and PERC products are destined to disappear from the market. What a success for global climate protection, which cannot be achieved with the current EU policy.
