The eclipse due to bring most of Europe into deep shadows on Friday morning will put an unprecedented strain on the region's electricity grid, turning off thousands of solar panels essential to power supply and rocking electricity markets. The moon will cross in front of the sun, blocking about 80 per cent of its light across Europe from 8 am to 11 am London time. In Germany, the eclipse will briefly turn off thousands of panels, which provide about 40 per cent of the nation's power on the most sunny days.
