Is sustainable market development possible?

Module manufacturers have once again adjusted their prices upwards. This is already the third or fourth price increase in the last six months, and there is no end in sight, writes Martin Schachinger of pvXchange. But why is it so hard to achieve long-term, sustainable development in the global solar market, at least on the part of manufacturers? Few other industries are so turbulent, with constant swings between excess supply and bottlenecks, between price collapses and price rises – and always to the breaking point of the market. Yet again, planning security is out the window.
