Don’t blame all of that loss on solar. Bosch derives over 50% of its revenue from producing auto parts, both OEM and aftermarket. When GM and Chrysler declared bankruptcy in the winter of 2008-09, Bosch lost about $400 million in accounts receivable.
Even so, solar panels have been a losing proposition for any company that isn’t Chinese.
Can you name the unsubsidized Chinese businesses that are profiting from solar?
