The solar eclipse 2015 provided an acid test for a continent that has placed a big bet on renewable energy—but whose aging electricity grids could buckle under the strain of a sudden drop in solar power.
This is the effect measured on my own solar panels during the eclipse. While (due to clouds) barely visible to the naked eye, the production during the eclipse dropped dramatically.
During the eclipse on it’s max (10h30 till 10h40) the generated power dropped to 8 watt.
