A look at the countries that have strongly invested in solar for many years indicates the solar trend is hot for awhile and then trickles out as the value of over supplied intermittent falls.
Germany installed solar as fast as 7 GW/yr in 2010, averaged 3 GW/yr for several years. Now they are down to 1.4 GW/yr, with 0.2 GW/yr required for replacement. Spain similarly slowed. California leads the US in new solar installation, but because of the growing daytime solar spike must now ramp up 13 GW of conventional power in three hours as solar fades in the evening, a scenario which is not practical to scale.
Germany still obtains over half generation from fossil fuel and 60% from all combustion. France by contrast pushed fossil fuels from 100% of non-hydro generation to single digit share in a dozen years via nuclear.
