Installed capacity for solar and wind is a parameter that seems pretty meaningless. For example (according to Wikipedia) the Agua Caliente solar project in Arizona (an ideal location), has an effective output of less than 30% of its installed capacity. A PV plant more comparable with France's conditions, the Lauingen Energy Park in Bavaria, has an output of 12% of its installed capacity.

Grandparent claimed that the bulk of renewable energy produced in France is hydro (and called me disingenuous). I just cited some statistics -- installed capacity as well as current effective output! -- to put his claim into context. Here are some more[1]: Energy production by source in France, 2019, Hydro 55.5 TWh, Wind 34.1 TWh, Solar 11.6 TWh. Obviously anybody is free to assign whatever value one wishes to terms like "bulk of", but those are the numbers.

Comparing installed capacity without discussing average load factor is also utterly meaningless.
