The analysis of excess supply is pretty detailed and robust.
Germany is actually making efforts to cut back their subsidy, not increase it.
It costs a fortune at the moment, which was OK whilst it was a tiny proportion of the grid, but is getting expensive.
On top of that, PV power which is tied in to the grid is a truly daft source of energy in Germany.
Just when you most need it, in the winter, it generates very little power, so the grid has to run more to make up, or would do if it produced any worthwhile power anyway.
In the summer when demand is slack then the grid is tied in to pay fantastic rates for electricity it doesn't need, as base load copes fine.
Solar PV power makes sense in hot climates where load peaks during the day in hot weather, in Germany it makes as much sense as ethanol from corn.
Japan may take some more, but has not got an unlimited budget.
China and other relatively poor countries are big on residential solar thermal, but not high cost PV, and won't go to the subsidies needed.
All is not lost though, as if they slash prices then it will actually start getting installed where it does make sense, where a/c needs are high.
California is the prime example, as it consumes most energy when it is sunniest.
So I would suggest that the second wave will have very different characteristics to the first, subsidised wave, with it actually being economic in some areas where transmission lines would otherwise need to be built and solar resources are good.
There should still be considerable cost pressure on suppliers though.

A side benefit is that as long as solar doesn't get any more expensive, it will get "cheaper" by default in that it will cost less in comparison to traditional power as it gets more expensive.

People don't buy $25,000 cars with cash, they finance them. People are finally waking up to the fact that they can do the same thing with a solar electric system. You can continue buying dirty centralized electricity from the utilities, or you can start producing your own decentralized renewable electricity.
