Half of the solar expansion goal for 2030
With an installed output of more than 107 gigawatts, half of the way is done – but the solar boom loses swing.
Half of the expansion of solar energy in Germany until 2030. According to the Federal Association of Solar Economics (BSW-Solar), around 107.5 gigawatts of performance are now installed. It should be 215 gigawatts by 2030. The now almost 5.3 million plants on roofs, balconies, open spaces over parking spaces and sometimes even on waters covered around 15 percent of German electricity requirements.
“Over the past 25 years, photovoltaics have developed from an expensive satellite technology for the cheapest form of electricity generation on earth,” says managing director Carsten Körnig. But despite the current success report, he is concerned: recently the expansion of solar power generation slowed down. Therefore, his association now sees the goal for 2030 and warns against reducing the pace.
“The electricity requirement grows and the solarization of roofs, facades and open spaces must not let up. Half of the path is done, but the next stage is not a sure -fire success,” says Körnig. In his eyes, a stronger expansion of photovoltaics leads and do not save any way. “The current heat wave and increasing climate damage make it painful.”
For the association, the expansion of savings is in particular in the foreground “in order to systematically develop the full photovoltaic potential”. Around two million battery stores with a total capacity of around 20 gigawatt hours are currently in operation in Germany. By 2030, however, a storage capacity of around 100 to 150 gigawatt hours. In order to advance here, the building law privilege of battery stores provided for in the coalition agreement must be implemented promptly.
Plants on and on houses make up most of the performance
According to the market master data register of the Federal Network Agency, the majority of the systems and the installed performance in the area of construction systems on or on roofs also fall buildings and facades. Here, 4.2 million plants with around 71 gigawatts are registered as in operation. This is followed by – measured after performance – open space systems. There are almost 20,000 of them, but they come to almost 33 gigawatts. Balcony power plants are much more common with a good million, but because they are much weaker, they only come up with a performance of almost a gigawatts.
