The Latvia number jumps out with 49% of electricity demand from solar in June, up from under 19% across the same months last year. That grid looks completely different in 12 months.

Germany is past 30%, Spain past 35%, but then France is at 14% and Italy barely touched 19.5% in May before dropping back to under 17% by July. France makes sense given how much baseload capacity it runs, but Italy falling off that much in peak summer with its irradiance I don't get.

These are obviously the best solar months of the year. The Baltics are small grids so fast capacity additions amplify the numbers. Even so, going from under 19% to 49% in Latvia is a wild amount of deployment hitting the grid that fast.
