According to data from the European Photovoltaic Association, in 2021, the newly installed photovoltaic capacity of the 27 EU member states will be 25.9GW, a year-on-year increase of 34%; Germany, Spain and the Netherlands will rank the top three. The market expects that the newly installed photovoltaic capacity in Europe will exceed 40GW this year, a year-on-year increase of more than 50%.

Previously, in order to reduce dependence on Russian energy and accelerate the transition to clean energy, the European Union released an energy plan called "RepowerEU", which plans to double the installed capacity of solar photovoltaic power generation by 2025, and install 600GW by 2030. The investment value is as high as 195 billion euros (about 1,342.8 billion yuan).

The plan proposes an increase of 15TWh of rooftop photovoltaic power generation in 2022, and requires that "by 2025, all new buildings, as well as existing buildings with energy consumption class D or above, should have rooftop photovoltaics installed".
