Are there any effects of the eclipse to Green Power generation?

The solar eclipse of March 20, 2015, was the first eclipse for which a significant impact on the power system occurred. The continental Europe and Great Britain generated about 90 Gigawatts of solar power and production was estimated to have decreased  by up to 34 GW compared to a clear sky day.  Also for wind farms there is a potentially smaller effect because as temperatures decrease during the eclipse, winds also slacken a bit, and this could cause wind turbines to rotate less vigorously.
