The eclipse of June 10 will not be a very spectacular spectacle in Europe. The moon will cover no more than a quarter of the sun’s disk, which will not produce effects visible to the naked eye. But for photovoltaic systems, this decline will be clearly felt, and the production of panels will decline as measurably as possible, especially where there is a lot of photovoltaics.
Transmission operators operating in the northern part of Germany – TenneT and 50Hertz estimate that the power supplied by photovoltaics may decrease by a maximum of 4.2 GW, of which in the network they manage – by approx. 2.8 GW. The remaining 1.4 GW may be lost in smaller, non-centrally controlled systems.
TenneT and 50Hertz emphasize that these are theoretical and maximum values, assuming that at the time of an eclipse there will be cloudless weather and the photovoltaics will work at full power. If it is cloudy, the drops will be correspondingly lower.
The most important activity of the operators is to increase the regulatory reserve. In the event of weather-related variability, the operators have prepared additional reserves, allowing to provide 0.5 GW of power, or possibly to reduce generation by 0.5 GW.
Because eclipse will also be visible from Poland, the Polish operator PSE also took into account the decline in PV generation.
This was taken into account in the forecasts, and the work plans were also adjusted accordingly, mainly by increasing provisions, PSE informed PAP.
According to the latest data published by PSE, at the end of April 2021, the installed capacity in photovoltaics was 4,690 MW. Not all installations will experience the eclipse to the same degree. While in the maximum of Thursday’s eclipse, just before 13 in Gdańsk and Szczecin, the moon will cover almost 26 percent. the Sun’s disk, it is in Krakow – only 14 percent.
An annular eclipse begins in the western Canadian province of Ontario. As it moves north, the moon’s shadow will pass through Hudson Bay and western Greenland, the North Pole, the East Siberian Sea, and end in the Kolyma Mountains.
Partial phases of the eclipse will be visible in Northeast North America, North and Northwest Europe, Northeast Asia and the entire Arctic Ocean.
