Last November SolarWorld confirmed plans to buy Bosch’s solar factories in Arnstadt, eastern Germany, comprising 700MW of cell and 200MW of module capacity.

SolarWorld did not disclose the terms of the deal at the time, but said that the plant transfer would not reduce its own financial resources.

But Bosch’s willingness to pay SolarWorld to take its factories and workers off its hands adds a new wrinkle to the drama.
