Freight costs, which represent around 4% of a solar module’s total costs, are increasing on trade lines between the Far East and the US West Coast, Northern Europe, and Mediterranean region.

Freight container shipping spot rates have increased to their highest level since 2022, according to data from Xeneta, a Norwegian ocean and freight rate benchmarking platform.

At the end of May, Xeneta said market average spot rates from the Far East to the US West Coast would reach $5,170 per forty-foot equivalent unit (FEU) on June 1. The figure is 57% higher than in May and the highest that spot rates have been for 640 days, surpassing the peak seen during the Red Sea crisis earlier this year. Spot rates are expected to peak at $6,250/FEU on the Far East to US West Coast line in June, just shy of the Red Sea crisis peak ($6,260).

On the Far East to North Europe trade line, spot rates are set to exceed the Red Sea crisis peak, reaching $5,280/FEU, compared to $4,839/FEU on Jan. 16. This will be the highest rate on this line for 596 days and an increase of 63% since 29 April.

Xeneta noted a similar story on the Far East to Mediterranean trade line, where spot rates are expected to edge past the Red Sea crisis peak of $5,985/FEU to reach $6,175/FEU. This would be an increase of 46% on May and the highest rates on the trade for 610 days.

With freight costs representing around 4% of a solar panel’s total costs, the spot rate increase is likely to have a knock-on effect on PV module prices.
