Foreign exchange is factor as I mentioned. One has to look at the performance of of companies which sell heavy to Japan to look for indication: SPWR and Motech. While we do not have clearly effects of the currency trading or foreign exchange with those companies on their income statements, GM which is isolated from those effects has improved for both. Both sell modules and clearly Motech sells cells. YEN depreciated against all currencies including TWD and RMB.
Effects will be different if payment terms are in USD, or RMB or YEN, amount of down payment and when payment is transferred and who pays for exchange fees. People read about companies in China affected by YEN, but they forget that solar markets operate on fix currency EURO and US. This is why prices went down in Japan in those to stabilize the market. Evidently the only group gained from it, yes hint : the Chinese. High margin and flexibility of selling everywhere else for less.
Those who bought data can see distribution to Japan by major companies so understand that first when you correlate impacts.
I am able to explain coherently here what happened with TSL, but if I am mistaken "aftermath" resident critic will molest this to death. I chose hint this to paid members.
In case of JASO the loss max outs around 6.5M on FX, this has no impact on GM portion of income statement. JASO does not use derivatives to hedge currencies, they had $488 (yes) hedge exiting the Q4. However consider my statements as an educated guess not a fact. On contrary, while prediction of future is over with SOL info, everyone else provides new piece of the puzzle.
