Deindustrialisation is mostly a consequence of high energy costs which is due to carbon taxes. They are fighting a problem which they have caused .
It has the obvious problem that it doesn't work at night and in winter. That's a big problem. I don't know how to fix that.
In other words, they count on non-solar backup... which not only makes solar more expensive, but basically redundant.
Until Solar+storage is the cheapest form of energy while delivering its promised output at 4AM after a cloudy day in freezing temperatures, the "solar is cheap" stuff is simply dishonest.
