On the chance that the solar price cuts somewhat mirror those in wind, some portion of the cuts are only to retain market share, and do not reflect actual production cost drop. This is dangerous to the margins of many companies, as we see with Vestas.

In wind Siemens and GE (and Alstom and Areva) are large enough and spread in all manner of other industries to absorb the margin cuts for some time, but the second tier companies and/or those only in wind are not. Nordex and REpower for example are also in tough times, as are the Spanish companies.

To the degree the cuts reflect economies of scale or technology efficiencies, such a program works. it's reasonable to suspect that even in solar that is not fully the case.
