On the morning of March 20th, 2015, Europe had the opportunity to witness a rare total solar eclipse. The previous one occurred in August 1999, and between the two more than 85 GW of photovoltaic panels were installed in Europe, or the equivalent of around 80 nuclear reactors. There was thus a great possible impact of last month’s eclipse on the grid. All media announced that it would be a great strength test and a potential threat.
Clean Horizon studied the effect of eclipse on Germany and its almost 40 GW of installed PV capacity using the secondary reserve.
